Alpine Yellowjacket Bait Stations are designed and labeled for use with Onslaught microencapsulated insecticide. When used together, they are the perfect combination for controlling scavenger yellowjackets (also commonly called meat bees) around residences, restaurants, resorts, campgrounds, zoos and other areas where humans or animals are harassed by yellowjackets. Onlsaught insecticide has an EPA approved label for yellowjacket baiting. Baiting instructions for Onslaught insecticide are included with our bait stations. A 12 oz. can of pet food or other suitable bait should be mixed with about 1.5 ml of insecticide (approximately 1/4 teaspoon). Please keep in mind that the liquid in the can is counted in the weight of the product, therefore, if you pour off the liquid you should reduce the amount of insecticide. In my experience though, the extra moisture helps keep the bait fresh. Many pest management professionals have successfully controlled yellowjackets using this method. If you find that yellowjackets are attracted to the bait alone, but won’t take the bait/insecticide mix, you may be experiencing repellency from the insecticide. This is usually a result of using too much insecticide for the amount of bait. Decreasing the amount of insecticide will usually correct this problem.
