What is the active ingredient that kills the yellow jackets? Will Onslaught harm honey bees?
Onslaught contains the active ingredient Esfenvalerate. Like most other insecticides Onslaught will kill honey bees if they come in contact with the product. If you use protein based food baits such as chicken, cat food or tuna you will greatly reduce the chance that honey bees will be attracted to the bait stations and contact the Onslaught.
