The 4th of July I was at my best friend's house where she is just learning to become a gardener. She told me to come look at her rose bushes which were "filled with ladybugs." My first thought was, oh no she must have aphids but when I looked they were covered with Japanese beetles! As I'm trying to Google what would be safe to use on them she grabbed her spray bottle of water and peppermint essential oil and sprayed the plants. Not only did they disappear but several hours later they were still gone. Just a thought.
Every time I do a research into my garden issues, I end up finding the answer and the solution to the problem on this channel. Jason, thank you so much for sharing your expertise for free ))
This is great! This is more detailed in solutions than I've seen in rose books. I have a container garden of roses, geraniums, hydrangeas and more, so when they find me, they party.
Not as bad as the rose sawfly maggots, surprisingly. Probably because of the short time frame and being slowed up by my plants being mostly up off the ground. But your video also brought up grass damage, and we have very spotty grass around here, which is something I hadn't thought of before.
Hello Jason; for sure so many of us are grateful for your extensive information. I keep all your videos not only because they are of great help should I have problems, but because they are all so interesting and I enjoyed them. As you know I just have a small garden which is more than plenty for me, and I adore my roses 🌹. Thank you 🌹🌺🌸
What an amazing job you’ve done in explaining and describing this pest and things we need to know to fight the fight for our garden! Thank you, so much…👍❣️
This year was the 1st time I experienced those beetles and they ate my Easter Lily down to the stem and I used some dish washing liquid mixed with water. This mixture did an excellent job.
@@irwu8860 I'm not sure. I have a new spray bottle for hair and I just put a couple of squirts and filled 1/2 bottle with water. Try 2 tablespoons, use cold water to keep from sudding
I have a problem with lily beetles on my lilies. They look like smaller rectangular ladybeetles, with no black spots on them. I’ve never seen Japanese beetles on them.
Thank u sooo much for this. Last year we had a bad invasion and have been looking everywhere on the internet how to deal with the problem. Finally, after your video, Feel armed and ready to get 'em!!!!!
Thank you for this video. This is the FIRST year I have ever noticed these beetles, but they came in by the thousands and shredded my cherry tree, my roses, and my grapes. I learned early on to catch them and put them in water. (no video needed for me to figure this out) but how to reduce them without affexcting much else is VERY GOOD to know. Thanks again.
Yes, it has been a tough season for JB (and other Scarab Beetle) infestations in NE, SE and MW. Denver Metro as well. fyi: Over years of use of beetleGONE! by Farmers/Growers (on crops ie berries, grapes, stone fruit, nuts, etc) they are finding that spraying at first sight of infestation reduces the population tremendously the rest of the season: not only is the product directly controlling the beetles but there is speculation that it may be disrupting the early beetles from depositing pheromones; thereby, lessening the attraction for more beetles to swarm in. As explained in the video, the primary use pattern of beetleGONE! is to protect your flowers, foliage, fruits & veggies from damage by adult beetles by spraying every 7-10 days during peak infestation of the beetles. It can be sprayed for highly effective organic control of adult beetles, weevils and borers without harming bees, butterflies nor ladybugs. It's certified for organic gardening and production. Simply mix in water and can be sprayed on edible garden plants, ornamental plants, trees or turf where JB (adults/grubs) feed. Product is also registered with a zero-day pre-havest interval; therefore, you can treat for beetles and harvest your food the same day. And there are no label restrictions for use around bees or flowering plants; therefore, beetleGONE! can be safely used while pollinators are active. This is the only non-chemical spray product on the market that performs at a high level like the leading chemicals (acelepryn, permethrin, imidacloprid, etc) but is safe for homeowners and pollinators alike. beetleGONE! tlc is a very versatile product: it can also be sprayed on your garden soil if you see grubs/grub damage or you can till/mix the dry product into garden or potting soil to control large and small grubs. It can also be used to control grubs in your lawn by mixing in water and spraying. Recommend spraying is at a rate of 3-4 ounces of product per Gallon per 1000 sf. Hope this helps!
Great advice!! Got to get after those grubs. But if you're on the losing end of a battle with adults, hand picking is tedious. Put a little sand in the bottom of your shop vac, and give the plants a once over. Japanese beetles would attack my climbing hydrangea and pole beans. We'd vacuum twice a day, alternating between plants to let them settle back down. Would loose a few leaves, but very efficient collection method to limit damage and decimate the population.
Thanks!!! new viewer. Very much to the point of subjects!!! Many other garden youtubers talk too much unessential to the subjects. I click off less than a minute viewing them. Thanks for the all educational points you put out. and I love your garden background too. looks so pristine!!
Thanks for that. We know that all that beetle trap stuff we didn't work for us and finally quit that mess. Tulle netting does protect as they can't get through it, but you have to figure out how to get your plants covered with it. Of course knocking them into buckets of water is fun, but who wants to stand there all day. Last summer I finally found the Neem oil that someone here purchased but we lost and never used. It seemed to do the trick, but this year I am going to treat the grubs and use your tips from this video with the BTg. Can't wait to see if it works!
This is first year that I’ve had a bad batch of these beetles. They only like my fragrant white roses. I followed old advice at first with the bait bags, I feel it just brought more to my yard! My husband layes down grub-ex, I then took down the bag, sprinkled dameous earth around roses. Next morning pulled off about 30-40 beetles by hand, then last evening, I followed your advice and deflowered all the white roses. I only found one beetle on my roses this morning! And found two others on my fern, but that’s it! We’ve learned our lesson, definitely treating yard for grubs and I will just debud my white shrub roses from June/July. They don’t seem to bother my red non-fragrant landscape roses.
Nothing much bothers Knockout landscape roses, the "plant and forget shrubs". But for Hybrid Tea roses you really have to spray every week to 10 days for fungus and insect pests. I use Bio- Advanced 3 in 1 spray.
Another excellent video Jason! We have thousands upon thousands of these beetles every year😢 they destroy our grapes/roses/plums/peaches every year!! We bought some pellets to distribute all over the ground to hopefully get a head up in the game.. I’ll also be purchasing this grub b gone💐
I think the Japanese beetles prefer my grapes vines even more than my roses. I have used BT on brassicas to kill the caterpillars but was not aware of BTg so thanks for the tip. I usually knock them into a bucket of water (without soap) then toss them into the pond to be eaten by the frogs. The frogs make short work of them.
I finally had to destroy my beautiful grape arbors. Disgusting. I was hoping some miracle would make them disappear. Whatever you do, do not put out the traps. They will draw in beetles from miles around and the nightmare gets worse.
Thank you this was so informative because I see now the damage going on with my plants. My hibiscus plant is like a skeleton when I checked yesterday. I will be on it, now I know what's attacking my plants. Thank you again, first time finding this channel.
They ate my grape vines last year and did so within a day or so. Amazing how fast they stripped the leaves and then moved on to a small cherry tree. This year having a lot of luck with Bag a Bug trap but will also try the suggestions from this terrific video. Best of luck!!!
I live in Tennesee and they emerge on my flowers in May and are still active through August. I have a huge yard in a rural community and they devour everything in my yard. I used the small pellets all over over my yards several times during the season. They are in my flower beds for more than 40 days and you are more than welcome to see this. I have been fighting these insects for over 25 years. It is impossible for me to put insecticide over my area and no one else seems to plant flower gardens as I do. I am alone in this area trying to fight this. I also have pastures and a creek. These beetles are very prolific and even eat the native vine called Virgin Creeper and also marigolds. They really started when aerial dusting was outlawed in this vicinity.
@@FraserValleyRoseFarm Thank you. I have huge flower gardens with lots of roses and about 40 azaleas plus all the others. The beetles are a nightmare in my yard and seven dust is about the only thing I can use and I have to use it almost daily to have a bloom. I have put down granules by the huge bag. It does not seem to deter any insects in my gardens. I fight all summer to have a pretty garden. I live in a rural area and I love the countryside. Thanks and good luck with your garden.
Very helpful. I've been picking off Japanese Beatles off my Virginia Creeper (VC) every day when they come out for about 3 yrs. I put a few drops of dishwasher soap in water in a small jar. I get about 20-40 daily. I tried liquid hand soap too, no they just swam around in that. I have a rose bush touching my VC but they absolutely prefer the VC. They also seem to like the location, hot. I finally bought spray for Japanese Beetles, after reading instructions, it says not to use on VC, whah! I will try the turf granules, other you mentioned when they go back into the ground. The battle goes on!
The two products you mentioned for the lawn to kill the grubs, would that hurt any deer or groundhogs that eat my lawn? I always keep my lawn pesticide free because I have puppies and lots of wildlife. But I hate these stupid beetles that kill my roses! Thank you for the great video! Appreciate any help you can give!
Jason - I thought that I had used your ideas this year - but in fact I failed to follow the main advice. 1) Here in central NY I killed my first Japanese Beetle on July 1. I killed a little less than a dozen today on August 29th. Although the individual beetles live for 40 days, the infestation will last 40 days from the last grub morphing to beetle = 2 months. 2) I planted the zonal geraniums all over the garden - they were completely unscathed. I didn't witness a paralyzed beetle - its possible that this happened. 3) SHOOT I did NOT use the BTG on the plants. Not sure why I didn't do this - didn't get on the list for some reason. (Also didn't use the NEEM which has a few drawbacks). 3) I disbudded all of my roses in July. That seemed to limit the damage - but as August wore on, I stopped disbudding because I wanted to have rose blooms (sadness). 4) I hesitated in the past using the Milky Spore Paenibacillus popillae on the lawn - but by the gods I will now! I just bought 20lb and may buy another 20. I was very effective with my big bucket of soapy water toward the middle of the summer I got really good at getting 10 at one Whamp! or softly sliding them off the cane into the bucket. It really did save my plants from a lot of damage- but they kept a-comin! Warmest regards Jennie
Thanks for the updates Jennie. I've heard back from gardeners in the worst hit areas where the JB has more than one generation per year, so the 40+ days becomes nearly all of summer and fall. Ugh. I've hear mixed things about the geranium trick. The research supports it, but it seems to be hit or miss in the real world, with some people posting pics of a JB graveyard at the bottom of their planter, and others saying the beetles had little interest. It's discouraging for sure!
Personally I haven’t had a big issue with the Japanese beetles, hopefully it stays that way, but WOW the view behind you. Beautiful the mountains low clouds, all the very green landscape, beautiful scenery. Thanks for sharing your information and specially your vista. 👍❤️😊
Thanks. As always your information is clear and scientifically based. I used to have only once blooming heirloom roses that finish before JB season, but decided that they weren’t going to win and have added others during the past few years. They also LOVE cuphea and a few others. You have provided new tools in my armament. Kathleen, 5b
Once again, Jason you come though with the info we need. I get these but not in huge numbers. I would like to keep it that way so I'm going to follow your advice.
I’m pretty sure this is what attacked my mature laurel/viburnum hedge last year. It was such a sight and basically still is, except new leaves are coming through green and shiny. I will be on my toes this year - thanks for the tips.
Thank you! Most comprehensive explanation I've found. Going to fight those buggers preemptively this year! I made the mistake last year of using the pheromone bag traps and all that did was attract bazillions of them into the yard. They ate my flowers, pole beans, grapes..... I appreciate that you've done your research and not just reporting anecdotal evidence.
Interesting video. Japanese beetles infest my garden every year, and can be especially deadly to my bean plants and many others. But I've never yet seen them on hydrangeas or geraniums, which you mention. Their tastes seem to differ from place to place and from season to season. For example, the first time I got them was on evening primroses. But I have the same plant growing now, and the beetles snub it in favor of the nearby raspberry bushes.
They've completely destroyed my roses and now starting to devour my Rose of Sharon's that are beginning to bloom. I've tried a few organic methods, traps, picked them off and fed them to my chickens where they've eaten so many, their sick of them! 😄 I didn't know about the grubs??!! I'll give that a try.
Jason is a wonderful teacher! This is the first time I've learned something about those troublesome beetles. I think they are more attracted to roses with more fragrance but red roses they seem to avoid - at least in my garden. I will try the Bonide spray this year.
Never had them until I planted a rose bush. Cut down the rose after collecting hundreds in a jug of soapy water. This year they have shown up in my lemon balm, albeit in much fewer numbers. Jug is ready!
Thank you for the finite explanation of who the Japanese Beetle is and how they make their way onto our plants, and now armed with new information, we can redirect them. =)
Thank you so much for this information. I usually go into my garden around 6 am with a bowl of soap water and drown over 100 beetles. They love my roses and okra leaves.
Plant your roses in front of your house under street lights. It always worked for me. We had a blackout for several hours one night and the leaves were eaten. I never spayed anything. If you have roses in a dark area as I do in my backyard (total darkness), try facing a solar light at the roses. They still have their leaves, uneaten.
Thanks. Funny, I had the exact opposite observation from one viewer: their roses under streetlights were badly eaten by JB while the ones elsewhere in the yard were left alone. I wonder if there's any science to clear it up?
@@FraserValleyRoseFarm I'm not sure what type of bug(s) attacked the roses in the dark. I'm from Hawaii. Bug control is all year round. Spider mites are the pain in my . . . 🙁 Happy bug hunting. 😉
Jason, I got in to your video during the Covid-19 pandemic and I wanted to say thank you for inspiring me to grow roses for the first time. Like a lot of people, I have been working from home; And because of the lockdown my garden has been my salvation. I purchased a number of roses (bareroot) and planted them at the same time (March 3rd 21). All of the roses have produced lovely leaves, however one of my roses has no leaves at all, I can tell it is not dead so is this normal please? Thanks!
Relaying my experience here in the Denver, CO area. Numerous stores (Home Depot, Lowe's, Ace etc) have recommended Neem oil to me. That appears to do nothing in my yard. Cutting off the rose buds and submerging them in a bucket of soapy water not only killed the existing beetles, but seems to have dramatically reduced the return of beetles to my roses. Also, putting grub killer in my yard in the spring/early summer appears to have dramatically slowed the onslaught from Japanese beetles. I haven't been able to eliminate them completely, but I have far less beetles on my roses this year than last and those two tools I've listed are the difference. Like I said, Neem oil seems to do just about nothing. I will be more aggressive on the grub killer when they return to the ground but I worry about killing grubs that the robins like in my yard in the spring. I hope I'm not killing robins inadvertently as well! Update: I've been spraying the beetles on my roses with dish soap and water the past couple days and just found that it is killing them! I'm using Dawn Ultra antibacterial liquid dish soap. I fill the spray bottle with water first, then squeeze in some dish soap so it doesn't create foam. I read that this will stick their wings together so they can't fly and expose them more to predators. I don't think I have any of their predators around because there are now a bunch of dead ones on the ground below my roses and nothing is eating them.
Thank you so much for sharing this - hearing your experience helps me craft my own pest control plan (when its so hard to find real info about these products amongst all the marketing-speak)!
@@judywelbaum4867 Yeah, I think any dish soap will work. I happen to use Dawn Anti-bacterial but I think any will work. The soap sticks to their wings so they can't fly, then it seems to burn them maybe? They fall off and die in a few minutes.
Woweeeeeee! Jason, this is - of course - the best advice that I've gotten. Last year I was an unwilling slave to and one by one executioner of the dreaded iridescent beetle. I had just put up a question on a rose FB on this and got the usual replies- with one exception. A writer had vacuumed up the critters in one season and was not bothered again. I'll still probably put that into my armory - but- as usual - your mastery of the matter shines out like a beacon of righteous gardening. Your friend Jennie ( I realize that this is my other identity that I've used for my phone TH-cam - but still the same Jennie)
The nematodes have really helped in my yard. I read that these grub killers actually get better each year after application and don't need to be reapplied every year. The love my plum trees, grapes and especially Virginia Creepers. My chickens also help a bunch! They go after the grubs in the mulched areas of my yard. I still have to pick them off everything first thing in the morning and in the evening. I do use neem oil on the top of my high grape trellis. Soapy water works the best. My lawn is another story....grubs or chickens which is worse? At least the chickens notice me and interact.
Thanks Margitt. I heard mixed results about Milky Spores, but that's another one that they say will get better established in the natural soil over the years of application.
I treated my yard with nematodes in the previous two years and I have seen a significant reduction in the number of Japanese beetles in my yard this year. BTW, thank you for your great video.
Great video Jason. Living in Vermont with sunny sandy soil, the battle will be starting soon with rose chafer. I see the BTG is supposed to be effective against them as well. After chafers come the J. Beetles so it’s usually a stressful summer as I do not use pesticides And in Vermont J.B. can linger almost til frost. I am cautiously optimistic about the BTG, I have ordered some (it is expensive) but so is vodka. LOL
So glad I came across your video It’s gonna be so helpful because I’m starting to see a lot of them and they are wreaking havoc on my zinnias 🤨 Thank you 👍🏻
This info is so helpful, thank you kindly. I have been very disheartened, so good to know about these methods. Btw, I like the fact that you are wearing your frayed sleeve jacket. A true gardener in his working garb! 😁
These buggers even go through my wisteria along with anything else in my garden. Since I learned about them releasing their pheromones when squashed, I’ve been keeping a container or can with soap water so that after I pick them off the plants, I drop them in there to die. I take extra pleasure doing it as they mate! 😄
Thank you for this wonderful Info, you are a delightful recourse! I really battled those jerks last year and I’m determined this year- they won’t eat my roses! I saw the comment about milky spore and was planning to try that this year...have you tried milky spore yourself? I’m guessing the best time to put it down is now? Thanks so much! Lauren
Jason, you are my new hero!!!! Knowledgeable and great with organic solutions. As a MG in CT- if you don’t mind- I plan on sharing this with clients. Question- do you have a science based reference? I would like to cite that as well. Thank you so much for sharing. You are a gem!
@@FraserValleyRoseFarm i also live in ct. spent most of the morning speaking 2 nurseries on the hunt for beetle gone & grub gone & it was like i was speaking a different language. with the exception of 1 garden nursery in plantsville ct. they shared with me the exact name of the supplier you have mentioned. nice guys ! they are sending me a 1lb. bag of beetlegone, can't wait to receive it.
I had to look this up again. Last year, I used the granules in May. It worked! I went from a major infestation in previous years to only running into 2 of the evil invaders last year! Thank you!
Thank you. They damaged my Dahlias and I have hand picked into a cup of soap water several times a day. I even use nettings for berries plants since they love blueberries too. Such annoying pest. What about Milky Spores? Would they work or they’re not affective as those you’ve suggested?
Hi Linda - Milky Spores are another bacterial solution to apply to the soil. I've heard they take a long time and consistently warm soil temperatures to build up to an effective population.
Thank you! Last year was the first year I've EVER seen the Japanese Beetle here in Colorado and they were nasty! I was regular with Neem oil but will also add to the arsenal the GrubGone!
We have 1 geranium (house plant) that goes out for the summer. Beetles never seem to find it but infest our garden, cana's, and sunflowers anyway. Wish I could find a way to lure them over to our chicken yard; might be good pest control but we would not be able to spray them there.
I have used peppermint essential oil with water and spray or leave a cup of it in the flower pot for the scent that repels them, it has been working so far, I have tried many things and do not want to use toxic products on my basil and food that these beetles love to eat!
I was out with my dogs around 2 am and saw the Japanese Beetles on the grass so quickly got my bug jar and collected them and this definitely cut back on my infestation this year.
Great video Jason! I was wondering if you ever tried to put a net over your roses or vines to protect them from the japanese beetles? Heard it was effective, but not so sure...
Thanks very informative ! For beetles I have heard to spray the leaves with detergent and hot pepper , do you have any organic solutions for Japanese beetles ? Also can you mention if the products you mention are organic or not ?since I use the pedals of one species I have to make jam , it is a very old and proven Armenian recipe I use.
The JB's devastated our rosa rugosa two years ago. I was picking them off twice a day, it was disgusting. We have had good results with (non-insecticide) Milky Spore, to kill the grubs. Granular, spread on the ground. Takes care of the "native" population, but not those who may fly in from the neighbor's. Certainly going to try the BTg this year for those miscreants. Those nasty beetles also like plum trees.
@@FraserValleyRoseFarm We have found one must be diligent with the applications (three times a year for two years), and ensure full coverage, meaning "no gaps."
In MN they stripped the peach trees bare 3 years ago, then i put nets around the peaches and they went after the raspberries, this year they seemed to prefer the beans. this was a very strange year for them tho, i am still seeing them in the garden a week after our average first frost date and the birds seem to finally want to eat them.
I try to time the first trim on roses and other ornamentals so that there is not as much stress on plants and there is less for the beetles to eat . And I use Diatomaceous earth on them and it's fairly effective . Diatomaceous earth has many uses and it kills many bugs . Anyway my plants put on their foliage when beetles are leaving. The timing is crucial.
Discovered by accident that they love the smell of my homemade cleaner. Has tea tree, cedar, and lemongrass so I guess it's the lemongrass; also contains dawn dish soap. Kills fleas on surfaces. Wish beetles would drown in a dish of it.
I used to work for the Oregon Department of Agriculture as an insect survey technician. My detection survey traps caught the first Japanese beetles in July and August 2016 west of the Portland city limits (most are found near shipping hubs and trapped before escaping, but this was an established population!) They are still trying to eradicate them, 8 years later! As is British Columbia. We do NOT want them to become established on the west coast! They cannot cross the Rockies without human assistance, so this is a valuable goal. The Oregonian nursery industry alone is a 1 billion dollar a year industry! Japanese beetle would make everyone’s costs increase and production decrease. I know eradication efforts were going well, but with biology, they need to get it completely down to zero or else the population will be able to reestablish and regain its foothold. But our State legislature did not fund it for next year, so hopefully shareholders (nurseries, vineyards, orchards, etc) will be able to prioritize and fund this strategic ecological defense endeavor while it is still a possibility.
Terrible infestation with several kinds of oriental beetles last year. If I use the granular btg on my lawn, it would be nice if I could add water to use as a spray on the plants. Is that a possiblity? To buy both products would be very expensive. I recently purchased the granular to start.
Hi Vanessa - I'm not a microbe expert at all, but since it's just a bacteria, I assume it could be infused into water and applied that way too. Is that a naïve assumption? Anyone?
Hi Carole. I've heard that it takes a fairly long season of warm soil for the milky spores to establish and become effective. The plus side is that once established, the protection seems to persist over many years.
They're a pain, but also have a lot of predators - so in a diverse garden, the populations can usually be managed without much intervention. If you do need to step in, I'd stay stick to the least toxic alternatives: th-cam.com/video/gAhfA0vlPik/w-d-xo.html
They love basil too. Bonus staying off my roses and attacking basil. Using BT & neem is helping. But if you want your roses left alone plant tons of basil
The 4th of July I was at my best friend's house where she is just learning to become a gardener. She told me to come look at her rose bushes which were "filled with ladybugs." My first thought was, oh no she must have aphids but when I looked they were covered with Japanese beetles! As I'm trying to Google what would be safe to use on them she grabbed her spray bottle of water and peppermint essential oil and sprayed the plants. Not only did they disappear but several hours later they were still gone. Just a thought.
Thanks Rose
Great!
great

Best of luck with them Allie!
I’m so glad to have found this video. I have been battling Japanese beetles for two years on my roses. I now know what to do. 🙏🏽
This is great! This is more detailed in solutions than I've seen in rose books. I have a container garden of roses, geraniums, hydrangeas and more, so when they find me, they party.
Oh boy - I hope your damage hasn't been too severe!
Not as bad as the rose sawfly maggots, surprisingly. Probably because of the short time frame and being slowed up by my plants being mostly up off the ground. But your video also brought up grass damage, and we have very spotty grass around here, which is something I hadn't thought of before.
Hello Jason; for sure so many of us are grateful for your extensive information.

How much dish washing liquid did you mixed with water please?
@@irwu8860 I'm not sure. I have a new spray bottle for hair and I just put a couple of squirts and filled 1/2 bottle with water. Try 2 tablespoons, use cold water to keep from sudding

Thanks - if I can keep people looking up at the mountains, they won't notice the weeds!
Thanks for that. We know that all that beetle trap stuff we didn't work for us and finally quit that mess. Tulle netting does protect as they can't get through it, but you have to figure out how to get your plants covered with it. Of course knocking them into buckets of water is fun, but who wants to stand there all day. Last summer I finally found the Neem oil that someone here purchased but we lost and never used. It seemed to do the trick, but this year I am going to treat the grubs and use your tips from this video with the BTg. Can't wait to see if it works!
Sounds like quite a struggle in your area!
Thank you Jason. I will be ready this rose season. Very appreciated to get clear information.
Thank you for sharing so much of your knowledge with us. You explain everything so well and I appreciate you very much.💚👍🐝
Thanks for the encouragement Peggy
They do a number on my yellow roses each and every year. Thank you for the advice.
Thanks Viki
This is first year that I’ve had a bad batch of these beetles. They only like my fragrant white roses. I followed old advice at first with the bait bags, I feel it just brought more to my yard! My husband layes down grub-ex, I then took down the bag, sprinkled dameous earth around roses. Next morning pulled off about 30-40 beetles by hand, then last evening, I followed your advice and deflowered all the white roses. I only found one beetle on my roses this morning! And found two others on my fern, but that’s it! We’ve learned our lesson, definitely treating yard for grubs and I will just debud my white shrub roses from June/July. They don’t seem to bother my red non-fragrant landscape roses.
Nothing much bothers Knockout landscape roses, the "plant and forget shrubs". But for Hybrid Tea roses you really have to spray every week to 10 days for fungus and insect pests. I use Bio- Advanced 3 in 1 spray.
Another excellent video Jason! We have thousands upon thousands of these beetles every year😢 they destroy our grapes/roses/plums/peaches every year!! We bought some pellets to distribute all over the ground to hopefully get a head up in the game.. I’ll also be purchasing this grub b gone💐
I think the Japanese beetles prefer my grapes vines even more than my roses. I have used BT on brassicas to kill the caterpillars but was not aware of BTg so thanks for the tip. I usually knock them into a bucket of water (without soap) then toss them into the pond to be eaten by the frogs. The frogs make short work of them.
Thanks Steve - I love that you're hand-feeding them to your frogs
I finally had to destroy my beautiful grape arbors. Disgusting. I was hoping some miracle would make them disappear. Whatever you do, do not put out the traps. They will draw in beetles from miles around and the nightmare gets worse.
@@winniegib31 I have never used traps but I heard if you do use them, to put them far away from what you trying to protect.
Is bt for worms and caterpillars the same as btg?

I used milky spore on the lawn. Worked well abt 10 yrs. Yesterday saw them on my ferns. Will use your idea on my 'Oh So Easy' roses. Thanks!
Thank you this was so informative because I see now the damage going on with my plants. My hibiscus plant is like a skeleton when I checked yesterday. I will be on it, now I know what's attacking my plants. Thank you again, first time finding this channel.
Thank you. Last year they ate my grape vine. First time I've had them. So I'm definitely getting what you recommend...
They ate my grape vines last year and did so within a day or so. Amazing how fast they stripped the leaves and then moved on to a small cherry tree. This year having a lot of luck with Bag a Bug trap but will also try the suggestions from this terrific video. Best of luck!!!
I live in Tennesee and they emerge on my flowers in May and are still active through August. I have a huge yard in a rural community and they devour everything in my yard. I used the small pellets all over over my yards several times during the season. They are in my flower beds for more than 40 days and you are more than welcome to see this. I have been fighting these insects for over 25 years. It is impossible for me to put insecticide over my area and no one else seems to plant flower gardens as I do. I am alone in this area trying to fight this. I also have pastures and a creek. These beetles are very prolific and even eat the native vine called Virgin Creeper and also marigolds. They really started when aerial dusting was outlawed in this vicinity.
Thanks for clearing that up Wynona. I'd heard that they can have overlapping generations in some climates
@@FraserValleyRoseFarm Thank you. I have huge flower gardens with lots of roses and about 40 azaleas plus all the others. The beetles are a nightmare in my yard and seven dust is about the only thing I can use and I have to use it almost daily to have a bloom. I have put down granules by the huge bag. It does not seem to deter any insects in my gardens. I fight all summer to have a pretty garden. I live in a rural area and I love the countryside. Thanks and good luck with your garden.
Very helpful. I've been picking off Japanese Beatles off my Virginia Creeper (VC) every day when they come out for about 3 yrs. I put a few drops of dishwasher soap in water in a small jar. I get about 20-40 daily. I tried liquid hand soap too, no they just swam around in that. I have a rose bush touching my VC but they absolutely prefer the VC. They also seem to like the location, hot. I finally bought spray for Japanese Beetles, after reading instructions, it says not to use on VC, whah! I will try the turf granules, other you mentioned when they go back into the ground. The battle goes on!
Hi. From Minnesota. Yes Japanese beetles I have great amount of them in my back yard. Thank you for sharing your great knowledge
The two products you mentioned for the lawn to kill the grubs, would that hurt any deer or groundhogs that eat my lawn? I always keep my lawn pesticide free because I have puppies and lots of wildlife. But I hate these stupid beetles that kill my roses! Thank you for the great video! Appreciate any help you can give!
No, these products won't hurt anything except beetles
Jason - I thought that I had used your ideas this year - but in fact I failed to follow the main advice. 1) Here in central NY I killed my first Japanese Beetle on July 1. I killed a little less than a dozen today on August 29th. Although the individual beetles live for 40 days, the infestation will last 40 days from the last grub morphing to beetle = 2 months. 2) I planted the zonal geraniums all over the garden - they were completely unscathed. I didn't witness a paralyzed beetle - its possible that this happened. 3) SHOOT I did NOT use the BTG on the plants. Not sure why I didn't do this - didn't get on the list for some reason. (Also didn't use the NEEM which has a few drawbacks). 3) I disbudded all of my roses in July. That seemed to limit the damage - but as August wore on, I stopped disbudding because I wanted to have rose blooms (sadness). 4) I hesitated in the past using the Milky Spore Paenibacillus popillae on the lawn - but by the gods I will now! I just bought 20lb and may buy another 20.
I was very effective with my big bucket of soapy water toward the middle of the summer I got really good at getting 10 at one Whamp! or softly sliding them off the cane into the bucket. It really did save my plants from a lot of damage- but they kept a-comin!
Warmest regards Jennie
Thanks for the updates Jennie. I've heard back from gardeners in the worst hit areas where the JB has more than one generation per year, so the 40+ days becomes nearly all of summer and fall. Ugh. I've hear mixed things about the geranium trick. The research supports it, but it seems to be hit or miss in the real world, with some people posting pics of a JB graveyard at the bottom of their planter, and others saying the beetles had little interest. It's discouraging for sure!
Personally I haven’t had a big issue with the Japanese beetles, hopefully it stays that way, but WOW the view behind you. Beautiful the mountains low clouds, all the very green landscape, beautiful scenery. Thanks for sharing your information and specially your vista. 👍❤️😊
Thanks Carmen. The cloudy mountains keep the yes up and away from the weeds
Thanks. As always your information is clear and scientifically based. I used to have only once blooming heirloom roses that finish before JB season, but decided that they weren’t going to win and have added others during the past few years. They also LOVE cuphea and a few others. You have provided new tools in my armament. Kathleen, 5b
Thanks Kathleen
Once again, Jason you come though with the info we need. I get these but not in huge numbers. I would like to keep it that way so I'm going to follow your advice.
Thanks Dennis
I’m pretty sure this is what attacked my mature laurel/viburnum hedge last year. It was such a sight and basically still is, except new leaves are coming through green and shiny. I will be on my toes this year - thanks for the tips.
I had this problem last year. Search Viburnum Leaf Beetle. Good luck.
@@dennistaft7868 I ended up having to have it sprayed at the beginning of June this year.
Thank you! Most comprehensive explanation I've found. Going to fight those buggers preemptively this year! I made the mistake last year of using the pheromone bag traps and all that did was attract bazillions of them into the yard. They ate my flowers, pole beans, grapes..... I appreciate that you've done your research and not just reporting anecdotal evidence.
Those traps are the worst, we quickly learned and threw them out.
Interesting video. Japanese beetles infest my garden every year, and can be especially deadly to my bean plants and many others. But I've never yet seen them on hydrangeas or geraniums, which you mention. Their tastes seem to differ from place to place and from season to season. For example, the first time I got them was on evening primroses. But I have the same plant growing now, and the beetles snub it in favor of the nearby raspberry bushes.
That's what I'm hearing from other commenters as well - that they can be a bit unpredictable
I think they like pole beans more than hydrangeas, but they will eat the hydrangeas if none of their favorites like roses and beans are available.
They've completely destroyed my roses and now starting to devour my Rose of Sharon's that are beginning to bloom. I've tried a few organic methods, traps, picked them off and fed them to my chickens where they've eaten so many, their sick of them! 😄 I didn't know about the grubs??!! I'll give that a try.
Jason is a wonderful teacher! This is the first time I've learned something about those troublesome beetles. I think they are more attracted to roses with more fragrance but red roses they seem to avoid - at least in my garden. I will try the Bonide spray this year.
Never had them until I planted a rose bush. Cut down the rose after collecting hundreds in a jug of soapy water. This year they have shown up in my lemon balm, albeit in much fewer numbers. Jug is ready!
Thank you for the finite explanation of who the Japanese Beetle is and how they make their way onto our plants, and now armed with new information, we can redirect them. =)
Thank you so much for this information. I usually go into my garden around 6 am with a bowl of soap water and drown over 100 beetles. They love my roses and okra leaves.
Very informative video. Very knowledgeable about the Japanese beetle and it’s lifecycle. Thank you for sharing your knowledge.
I saw damaged roses a few days ago. It is a good review. Thank you!
Plant your roses in front of your house under street lights. It always worked for me. We had a blackout for several hours one night and the leaves were eaten. I never spayed anything. If you have roses in a dark area as I do in my backyard (total darkness), try facing a solar light at the roses. They still have their leaves, uneaten.
Thanks. Funny, I had the exact opposite observation from one viewer: their roses under streetlights were badly eaten by JB while the ones elsewhere in the yard were left alone. I wonder if there's any science to clear it up?
@@FraserValleyRoseFarm I'm not sure what type of bug(s) attacked the roses in the dark. I'm from Hawaii. Bug control is all year round. Spider mites are the pain in my . . . 🙁 Happy bug hunting. 😉
Jason, I got in to your video during the Covid-19 pandemic and I wanted to say thank you for inspiring me to grow roses for the first time. Like a lot of people, I have been working from home; And because of the lockdown my garden has been my salvation. I purchased a number of roses (bareroot) and planted them at the same time (March 3rd 21). All of the roses have produced lovely leaves, however one of my roses has no leaves at all, I can tell it is not dead so is this normal please? Thanks!
I can only advise patience. The bare-root harvest and storage process can leave some varieties very slow to resprout.
The damage looks serious.
Nice info!! Nice view!! 👍
Thank you!
Relaying my experience here in the Denver, CO area. Numerous stores (Home Depot, Lowe's, Ace etc) have recommended Neem oil to me. That appears to do nothing in my yard. Cutting off the rose buds and submerging them in a bucket of soapy water not only killed the existing beetles, but seems to have dramatically reduced the return of beetles to my roses. Also, putting grub killer in my yard in the spring/early summer appears to have dramatically slowed the onslaught from Japanese beetles. I haven't been able to eliminate them completely, but I have far less beetles on my roses this year than last and those two tools I've listed are the difference. Like I said, Neem oil seems to do just about nothing. I will be more aggressive on the grub killer when they return to the ground but I worry about killing grubs that the robins like in my yard in the spring. I hope I'm not killing robins inadvertently as well! Update: I've been spraying the beetles on my roses with dish soap and water the past couple days and just found that it is killing them! I'm using Dawn Ultra antibacterial liquid dish soap. I fill the spray bottle with water first, then squeeze in some dish soap so it doesn't create foam. I read that this will stick their wings together so they can't fly and expose them more to predators. I don't think I have any of their predators around because there are now a bunch of dead ones on the ground below my roses and nothing is eating them.
Thank you so much for sharing this - hearing your experience helps me craft my own pest control plan (when its so hard to find real info about these products amongst all the marketing-speak)!
Please do not use antibacterial soap. They can be killed just as easily with regular Dawn dish soap.
Can you use any dish soap????
@@judywelbaum4867 Yeah, I think any dish soap will work. I happen to use Dawn Anti-bacterial but I think any will work. The soap sticks to their wings so they can't fly, then it seems to burn them maybe? They fall off and die in a few minutes.
Woweeeeeee! Jason, this is - of course - the best advice that I've gotten. Last year I was an unwilling slave to and one by one executioner of the dreaded iridescent beetle. I had just put up a question on a rose FB on this and got the usual replies- with one exception. A writer had vacuumed up the critters in one season and was not bothered again. I'll still probably put that into my armory - but- as usual - your mastery of the matter shines out like a beacon of righteous gardening.
Your friend
Jennie ( I realize that this is my other identity that I've used for my phone TH-cam - but still the same Jennie)
I'm definitely glad there's a new tool for the fight!
even mylocal garden centers couldn't give this good quality advice. Thanks !!
The nematodes have really helped in my yard. I read that these grub killers actually get better each year after application and don't need to be reapplied every year. The love my plum trees, grapes and especially Virginia Creepers. My chickens also help a bunch! They go after the grubs in the mulched areas of my yard. I still have to pick them off everything first thing in the morning and in the evening. I do use neem oil on the top of my high grape trellis. Soapy water works the best. My lawn is another story....grubs or chickens which is worse? At least the chickens notice me and interact.
Thanks Margitt. I heard mixed results about Milky Spores, but that's another one that they say will get better established in the natural soil over the years of application.
I treated my yard with nematodes in the previous two years and I have seen a significant reduction in the number of Japanese beetles in my yard this year. BTW, thank you for your great video.
Thank you so much. I think this explains both the brown patches in my lawn and the holes in my grape leaves! Thank you!
Great video Jason. Living in Vermont with sunny sandy soil, the battle will be starting soon with rose chafer. I see the BTG is supposed to be effective against them as well. After chafers come the J. Beetles so it’s usually a stressful summer as I do not use pesticides And in Vermont J.B. can linger almost til frost. I am cautiously optimistic about the BTG, I have ordered some (it is expensive) but so is vodka. LOL
Thanks Robin. I think I'll use that line with my wife next time I'm buying an expensive plant
👌😄
we had a bit on trees...but thanks for the notes, I will be looking for it in the stores.
So glad I came across your video
It’s gonna be so helpful because I’m starting to see a lot of them and they are wreaking havoc on my zinnias 🤨
Thank you 👍🏻
This info is so helpful, thank you kindly. I have been very disheartened, so good to know about these methods. Btw, I like the fact that you are wearing your frayed sleeve jacket. A true gardener in his working garb! 😁
These buggers even go through my wisteria along with anything else in my garden. Since I learned about them releasing their pheromones when squashed, I’ve been keeping a container or can with soap water so that after I pick them off the plants, I drop them in there to die. I take extra pleasure doing it as they mate! 😄
I wasn't aware that squishing them will release pheromones. I'll start soapy water baths for them too. Thanks
Jason! The beetles have attack our Blackberries. Should we address them in the same way as you described for the roses? Thank you!
Yes, or maybe look at milky spore as an option
@@FraserValleyRoseFarm
Thank you!
Thank you for this wonderful Info, you are a delightful recourse! I really battled those jerks last year and I’m determined this year- they won’t eat my roses! I saw the comment about milky spore and was planning to try that this year...have you tried milky spore yourself? I’m guessing the best time to put it down is now? Thanks so much!
Lauren
Hi Joe. I haven't tried Milky Spore - I heard both positive and negative about it, and it takes a few years to establish in the soil.
I enjoy your channel so very much. We are in Maine and I have a few small rose gardens. Your videos have helped me cultivate beautiful gardens!
Jason, you are my new hero!!!!
Knowledgeable and great with organic solutions. As a MG in CT- if you don’t mind- I plan on sharing this with clients. Question- do you have a science based reference? I would like to cite that as well. Thank you so much for sharing. You are a gem!
Hi Marie. Here's a s presentation from one of the suppliers of BTg: greenearthagandturf.com/btg-grubgone-beetlegone-cnla-presentation.pdf
Thanks so much Jason. Be well.
@@FraserValleyRoseFarm i also live in ct. spent most of the morning speaking 2 nurseries on the hunt for beetle gone & grub gone & it was like i was speaking a different language. with the exception of 1 garden nursery in plantsville ct. they shared with me the exact name of the supplier you have mentioned. nice guys ! they are sending me a 1lb. bag of beetlegone, can't wait to receive it.
Beautiful! I hate Japanese beetles!!
Thanks for your fine presentation. Very helpful.
As always, incredibly succinct and helpful! Thank you!
My pleasure. Thanks for watching
I had to look this up again. Last year, I used the granules in May. It worked! I went from a major infestation in previous years to only running into 2 of the evil invaders last year! Thank you!
Glad to hear it!
Thank you. They damaged my Dahlias and I have hand picked into a cup of soap water several times a day. I even use nettings for berries plants since they love blueberries too. Such annoying pest. What about Milky Spores? Would they work or they’re not affective as those you’ve suggested?
Hi Linda - Milky Spores are another bacterial solution to apply to the soil. I've heard they take a long time and consistently warm soil temperatures to build up to an effective population.
Oh yes hi Jason . For anyone reading this I trust Jason imperacly for help . He is one of the smartest. Thank you
Thank you! Last year was the first year I've EVER seen the Japanese Beetle here in Colorado and they were nasty! I was regular with Neem oil but will also add to the arsenal the GrubGone!
I noticed them on my okra today in GA on 4th of July thanks for the info!!
We have 1 geranium (house plant) that goes out for the summer. Beetles never seem to find it but infest our garden, cana's, and sunflowers anyway. Wish I could find a way to lure them over to our chicken yard; might be good pest control but we would not be able to spray them there.
I have used peppermint essential oil with water and spray or leave a cup of it in the flower pot for the scent that repels them, it has been working so far, I have tried many things and do not want to use toxic products on my basil and food that these beetles love to eat!
VERY good info Thank YOU! I have them very bad here in the middle of neb.
Great information! Thanks for all the tips.
Glad it was helpful!
Are Milky Spores the same thing you are using? Thanks
If you really want to see them, you can carry a electric torch/flashlight and check out the garden in the evening or night.
Great information! Thank you so much.
JB shred my raspberries and sunflowers. I wanted to plant a climbing rose over an arbor but know I reconsider.
I was out with my dogs around 2 am and saw the Japanese Beetles on the grass so quickly got my bug jar and collected them and this definitely cut back on my infestation this year.
Great video Jason! I was wondering if you ever tried to put a net over your roses or vines to protect them from the japanese beetles? Heard it was effective, but not so sure...
Sounds difficult to manage with larger roses
Thanks very informative !
For beetles I have heard to spray the leaves with detergent and hot pepper , do you have any organic solutions for Japanese beetles ? Also can you mention if the products you mention are organic or not ?since I use the pedals of one species I have to make jam , it is a very old and proven Armenian recipe I use.
Thanks Maria. Both the nematodes and the bacteria a mention here are biological controls, and so they're organic.
The JB's devastated our rosa rugosa two years ago. I was picking them off twice a day, it was disgusting. We have had good results with (non-insecticide) Milky Spore, to kill the grubs. Granular, spread on the ground. Takes care of the "native" population, but not those who may fly in from the neighbor's. Certainly going to try the BTg this year for those miscreants.
Those nasty beetles also like plum trees.
Thanks. Glad to hear about your success with Milky Spores. I'd seen mixed reviews.
@@FraserValleyRoseFarm We have found one must be diligent with the applications (three times a year for two years), and ensure full coverage, meaning "no gaps."
Would these measures also be helpful for the Hoplia Beetle? In California we don’t get Japanese beetles but this is very similar damage etc.
So long as the BTg is applied to something they'll consume, it should be effective.
In MN they stripped the peach trees bare 3 years ago, then i put nets around the peaches and they went after the raspberries, this year they seemed to prefer the beans. this was a very strange year for them tho, i am still seeing them in the garden a week after our average first frost date and the birds seem to finally want to eat them.
Thank you. Will certainly give these items a try
The most informative video ever
I try to time the first trim on roses and other ornamentals so that there is not as much stress on plants and there is less for the beetles to eat . And I use Diatomaceous earth on them and it's fairly effective . Diatomaceous earth has many uses and it kills many bugs . Anyway my plants put on their foliage when beetles are leaving. The timing is crucial.
Thank you for making this video. It is going to save our grapes.
My pleasure
Extremely helpful and informative. Thank you so much.
I just noticed your video and I'd like to say thank you I didn't know how to take care of them but no I do
Discovered by accident that they love the smell of my homemade cleaner. Has tea tree, cedar, and lemongrass so I guess it's the lemongrass; also contains dawn dish soap. Kills fleas on surfaces. Wish beetles would drown in a dish of it.
Thank you so much for the informative tips. Super helpful. Will start with the grub control method now. Really appreciate it!!🌹🌹🌹
I used to work for the Oregon Department of Agriculture as an insect survey technician. My detection survey traps caught the first Japanese beetles in July and August 2016 west of the Portland city limits (most are found near shipping hubs and trapped before escaping, but this was an established population!)
They are still trying to eradicate them, 8 years later! As is British Columbia. We do NOT want them to become established on the west coast! They cannot cross the Rockies without human assistance, so this is a valuable goal. The Oregonian nursery industry alone is a 1 billion dollar a year industry! Japanese beetle would make everyone’s costs increase and production decrease.
I know eradication efforts were going well, but with biology, they need to get it completely down to zero or else the population will be able to reestablish and regain its foothold. But our State legislature did not fund it for next year, so hopefully shareholders (nurseries, vineyards, orchards, etc) will be able to prioritize and fund this strategic ecological defense endeavor while it is still a possibility.
Thanks so much! Your videos are always so informative.
Excellent information
Thanks Fern
Terrible infestation with several kinds of oriental beetles last year. If I use the granular btg on my lawn, it would be nice if I could add water to use as a spray on the plants. Is that a possiblity? To buy both products would be very expensive. I recently purchased the granular to start.
Hi Vanessa - I'm not a microbe expert at all, but since it's just a bacteria, I assume it could be infused into water and applied that way too. Is that a naïve assumption? Anyone?
Great video! Does this work for chafer beetles as well? They love my dahlias. I am in Zone 6b. Thanks!
Is a fly trap the same as a Japanese beetle trap? Same pheromones to attract them?
Thank you for the clear information! What are your thoughts on milky spore?
Hi Carole. I've heard that it takes a fairly long season of warm soil for the milky spores to establish and become effective. The plus side is that once established, the protection seems to persist over many years.
They tried but didn't like my Blueberry and roses but adored my Cherry tree!
Another useful video! Thank you Jason
This was actually really helpful, thank you so much ❤
Hello Jason, aphids is the other garden pests that I have with roses. How can I protect my young roses buds? This video was very helpful, thank you.
They're a pain, but also have a lot of predators - so in a diverse garden, the populations can usually be managed without much intervention. If you do need to step in, I'd stay stick to the least toxic alternatives: th-cam.com/video/gAhfA0vlPik/w-d-xo.html
They love basil too. Bonus staying off my roses and attacking basil. Using BT & neem is helping. But if you want your roses left alone plant tons of basil
Thanks!
