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!!
I had bees entering between the roof and soffit. I used the Tempo 1% Dust product applying it with the B&G Bulb Duster 1150. I applied a good dusting by inserting the appliance it into the opening were the bees were getting in. Did this 2x a day for 2 days; but, had no luck getting rid of the bees. Basically, after I dusted, the bees would swarm out, and in about 15 minutes, they were back to their routine; flying back in-and-out of the opening.
