The most commonly known wasps, such as yellowjackets and hornets, are eusocial, living together in a nest with an egg-laying queen and non-reproducing workers. Many wasps attack and sting prey items that they use as food for their larvae. Most predatory wasps paralyze their prey and lay eggs directly upon the bodies, and the wasp larvae consume them. Wasps are considered pests when they become excessively common, or nest close to buildings. People are most often stung in late summer.
