What is yellow jacket bait made out of?

Yellow jacket bait typically consists of a protein or sugar-based attractant combined with an insecticide. Common ingredients include sugars like corn syrup or fruit juice to lure the yellow jackets, along with active ingredients such as pyrethroids or carbamates to eliminate them. The bait is designed to attract the wasps to consume it, leading to their demise while minimizing hazards to non-target species.
