I've been using this method for several years and I find it to be very effective. I use other methods as well but I like this method for new packages or older hives in the spring. . I also like formic pro strips but you can't use them and feed sugar syrup or pollen patties while the strips are on. I always feed new packages and most of the older hives in the spring before a nectar flow. This method is only effective if little to no capped brood is present. I treat in the spring and fall always and will treat in the summer if my mite counts are high.
I notice you are not wearing the eye protection nor the respirator when you have your bee suit on and applying the acid to the hive. So is the protection not really necessary?
Hi this is a helpful video thank you! Questions: -Is the max total of OA solution per hive is 50ml, even if you have two deeps or more on the hive? If you only dribble on one of the deeps, which one should you apply the treatment to? -are you doing regular mite monitoring and treating only if the Varroa counts are above threshold to prevent resistance/exposing bees unnecessarily, or you treat regardless? If treating without counting mites, is that done in Spring and late Summer? -do you treat with OA both in the spring and in the late fall? If so, what months in each season? thanks so much
It's max x50 ml per Hive* (that being a x10 Frame Box !!!) , she said so.... Do it on the Brood Box only.... 👀 Eg x5mls dribbled onto per Seam of Bees.... The Bees BETWEEN the Frames. 😎 Same applies to Nucs... it's "x5ml per Seam of Bees" ! * x5 Frame Nuc needs 1/2 the quantity of made up O/A Solution !!! 👍
I do discard them. I usually purchase a box of them. They are pretty inexpensive and are disposable. I use the glass because it's convenient. It is designated for use only with OA. I discard the extra from the jar when I'm done and wash, dry and store it. Great question!
Questions: Is OA something found naturally in beehive? Also, should this dribble always be used in weather under 50 degrees? And as for the measurements, you made out the amount for 5 hive but almost used all of it. How does that work? Confused.
Good questions. Yes, OA is found naturally in small quantities but not high enough to treat mites. I would not use it in lower temps. The recipe is for 5 hives. If you are treating less, than I would discard the rest. I had treated other hives prior to the one in the video. I would definitely not recommend administering more than the recommended amount of OA.
I love your videos! I have a question that has puzzled me for a while about OA treatment. If its recommended to label containers and not mixing them up with every day cooking dishes inside the house, etc., and having to use proper PPE, is this something that can contaminate the honey that will be consumed? No offense, but it would be an honor to have a good looking beekeeper like you as a friend :)
Thank you! OA is a naturally occurring compound in honey. There are some beekeepers I have met that do consume the honey produced during OA treatment. Personally, I do not treat with OA with supers on. Also, it's really effective in a broodless hive. You are going to have capped brood in the hive during nectar flow, so the treatment would not be effective at that time anyway.
The recipe we have and what our agri department recommends is to used oxalic acid 97.0% and one that pure for use in treating bees . Our recipes calls for 1/4 tspn for a liter of sugar syrup. The amount y’all mixed there seems a tad bit strong unless the oxalic acid is much less than 97.0% pure .
This recipe will yield a 3.2% strength OA mixture and is medium strength that will work for most hives. It's a widely used recipe. I'm not familiar with the specific recipe you are using. One of the great things about beekeeping is there is so many different ways to do it.
@@sweetbeefarms did I read correctly on your website that you use 97% oxalic acid, and 8.75g for the 5-hive amount? I'm in NZ and the oxalic acid I just purchased (which I assumed was standard but doesn't seem to be) says it is 99.9% purity. Do I need to adjust any quantities? I can't find ANY information online and I've looked at so many different recipes that I'm highly confused and don't know what to do.
Some Years later. . . Here in Scotland 🏴 we can use Oxalic Acid as either a Vapour or via a 1: 1 Trickle. (Dribble US terminology !) Our UK Agri / Vet Med Laws mean we have to use "Api-Bioxal" (OA) 98% pure as it has Glucose/Silica in it too. Oxalic Acid Crystal's (Wood Bleach) are 99 % I think. . . But (in UK) is illegal to do Varroa Mite Treatments with "O.A" via the Wood Product route. 🙄 Recipe : Up or Down Quantities to suit Hive Size & Numbers. 100g Tap Water (Tepid) 100g White Sugar 7.5g Oxalic Acid V.M Meds* Or as : x1 Level Teaspoons worth. [Keep spoon for O/A use only, in your Beek Tool Box !] *Your Laws might say OK to do 'Wood Bleach'. 😉 While at a Vet or (Chemist, Pharmacy Store,) purchase some "60ml Drench / Oral" Syringes." For use with Liquid Medications etc etc. Both are around £2/$1.50 I guess. . . Excellent for Dosing the Hive with O/A at the Correct Amount each time ! . . . And can be used time and time again. ✔️ Once Oxalic Acid Solution (Syrup) is made up : Draw up eg x 60ml into the Syringe, making sure Air is expelled thru the Tip or end Nozzle. Like setting it to "Zero " before doing a Dose. Every "Seam of Bees" gets Trickled with "x 5mls ONlY." What's a Seam you Ask ??? A Seam : Is the 'Packed' or Busy amount of Bees in between each Bee Frame. So a x10 Frame Brood Box in eg a Langstroth Hive, will be " x9 Seams of Bees." If its a Nuc do above, but you will have less 'Seams'. So do x 5ml over x4 Seams if it's a x5 Frame Nuc. A less busy (populated) Hive, you can Dose say x 3ml per Seam. You can't really overdose, but with less Bees x 5mls might make them a bit Wet or Soggy. You want them to "Groom" each other. Not Drown in a Sticky syrupy downpour. . . 🤭 Oxalic Acid 1:1 Solution is : 3.2 % Strength Medication per x 5mls Dose. Above Ingredients will equal to " x167 mls" Total : So enough to do say x3 or x4 Brood Boxes (Colonies.) Do the Math(s) xxx x 5mls ! Double or Triple up the quantity for more Hives. Best to make more batches, as needed, rather than have loads left over. . . It will just spoil and needs to be disposed of, not put through down your Sink, or Drainage etc. But in some waste Ground like in the Earth of your Garden (Dirt in Yard.) Bees won't want to Forage off it, say in an open Syrup Feeder. "O/A Syrup" is NOT a Food, its a Treatment ! So do Dispose of any of that left over 'syrup' Safely ! It's only a pence, or cents worth... Hope this helps. 😎 🐝🐝🐝🐝🐝🐝🐝🐝🐝🐝 Happy Beekeeping 2023 🐝🐝🐝🐝🐝🐝🐝🐝🐝🐝 Oxalic Acid when handled via a Trickle / Dribble is quite harmless to handle. Wear latex Gloves if you want, but a Teaspoon's worth of O/A Crystal's into warm water isn't a 'stirring' hazardous operation. 🤭 (OK don't splash it about !) But you don't need a Filtered / Respiratory Mask like this Video showed !? ! That's for when O/A is Vapourised into a 'Toxic' Gas. Then you need Mask, Goggles, Gloves of the Heavy Industrial kind. 👍

What amount of each ingredient do you use? Do we apply the solution on frames that contain fall feed such as bee bread and honey?
I know this is old but baking soda neutralizes it for discard..also taking lemon juice keeps oxalate out of bloodstream and you whiz it out instead of kidney stones, more valid for vaporizer but just sharing,good video!
Can we use a spray?
I will be trying it this year thank you for showing us how it’s done ✅
How long have you been using this method.... and how effective is it.... how oftern do you treat?

How often do you do this?
Thank you..please explain how much oxalic acid and water and suger mixing?

The Bees BETWEEN the Frames. 😎

How often do you apply this? Is it like vaporizing. Every 7 days x3 or
If there is brood in the hive, I do it every 6 days x 3.
Do you discard the syringe after use? Is there a reason you use a glass mason jar to prepare OA versus a plastic container?
I do discard them. I usually purchase a box of them. They are pretty inexpensive and are disposable. I use the glass because it's convenient. It is designated for use only with OA. I discard the extra from the jar when I'm done and wash, dry and store it. Great question!

@@sweetbeefarms understood. I will follow the five hive measurement and only put 10grams of OA
How soon can you put the super back on/ will the honey be safe to consume?
OA can be used when supers are on the hive. There is oxalic acid in honey in small quantities naturally.
Paper bowls are disposable and safe for mixing. Place plastic wrap over your scale.
Could you use mineral oil with the OA instead??
Could you put up the measurements you used. Thanks
Found it, thank you
I'm glad you found them!
Jackie Eid Hi, Jackie! Where did you find it? I'm looking for these measurements as I want to try this method. Thank you!

Why not? Water has weight.
