Here in Michigan we been invaded by the nasty european paper wasp. They have the same body and shape of the brown wasp. However those little suckers are vicious to say the least. They also have 2x the venom of regular wasp. Bees absolutely do not like pine oil. Pinesol original formula is the best. The contents are 10% pine oil and detergents and water. It not only will kill the wasp within seconds but it repeals them from coming back. Wasp, hornets, yellow jackets, bumble bees (the friendly ones that circle you) all are susceptible to this product. If you want a non pesticide solution try this: mix in a sprayer at least 90% or full strength original Pinesol ( no imitations ) with water. Spray the nest and BANG dead in seconds the stragglers will also vacate. Also for prevention a 80% mix sprayed on problem areas will detract nests from being constructed. I've used this method for years with flawless results. PLEASE PLEASE don't kill the honey bees though they are responsible for pollinating and giving us all the honey, wax, and fruit we eat. I think it was Dan Rather the reporter that said "if the honey bees disappear so will humans" be safe and respect nature.
