Yellowjackets

Yellowjackets are the most likely dangerous stinging insect in the United States. Their name is based on the distinctive black and yellow color pattern of their body. Nests are often located underground, and they become extremely aggressive when their nests are disturbed. If the nest can be located, elimination of the colonies should be done only at night when most of the yellowjackets are in the nest and less active. Aerosols and dust formulations of pesticides usually work best.
