you can't they are all fake, they just emit a noise the Animals can hear, but eventually they get used to the noise, the same way birds in cities get used to the noise from cars and people etc. I mean if a blinking light and a noise scared Foxes and birds There would be no such thing as an urban fox, or an urban pigeon. Your dog or cat would not come into the house if the TV was on or if someone was playing loud music. It's not like cities are pitch black Or silent, every single one of these so-called sonic Animal repellers is fake in the fact that they don't repel anything.
Where do you let us hear yhe noise?
How do they repel animals including dog yet be petdog friendly???
