Yellowjackets forage for meat, ripe fruit, sweets (including soda), and garbage. Even when they are not near their nests, they can be numerous in picnic areas, around garbage containers, and in orchards. Yellowjacket traps can offer some relief. Sealing garbage well helps, also. Individual yellowjackets—in a car, or on the lip of a soda can—can be gently nudged away with a piece of paper. Never swat a yellowjacket on your body—it could prompt a sting.
