So there are many ideas and theories for yellow jacket and wasp traps out there but i found an idea that i have tested this late summer/early fall that works. Most traps only trap the foragers and maybe if you are lucky a queen but they keep coming. There have been at least a few universities that have experimented with different baits and inecticides to kill the entire nest of wasps, not just the foragers. They all came up with similar results: By taking a can of minced chicken meat or chicken flavor wet cat food and mixing 5% Fipronil into it, the wasps will come into contact with the fipronil, carry it back to the nest and over the course of a couple weeks will have infected the entire nest and by then the fipronil will attck their nervous systems and kill all of them. Larva and all. I used to have such a bad issue with wasps but after a couple weeks they were nearly non existent in my area. Since its meat that the insecticide is mixed with the honey bees will not be attracted to it. Ill set these out with their own stands and covers next spring to prevent any larger animals from getting into them.
