Paper wasp nest with paper wasps

Sheltered, elevated sites such as building eaves, window frames, porches, and vegetation, especially in warm regions.

Adults eat nectar and other sugary liquids; they capture and chew caterpillars and other insects to feed larvae.

Colonies build open-comb nests from wood fibers mixed with saliva. Adults defend the nest and may sting repeatedly when disturbed; colonies are usually seasonal.

Stings can be painful and occasionally trigger severe allergic reactions. They benefit gardens by pollinating plants and controlling caterpillars and other insects.
