I am a bee keeper and was looking for a way to get rid of the yellow jackets that stalk my backyard hives. I did not order this because tucked in some reviews was the fact that people used this to kill honey bees! Why you would do that I don't know, very sad, but I thought it was important to point this out loudly. If you want to protect pollinators find another way to kill wasp. Mason bees and honey bees are our friends!!
