Common Name: Paper wasp
Scientific Name: Polistes sp.
Order: Hymenoptera


Paper wasps should not be confused with yellowjackets (Vespula squamosa Drury) and baldfaced hornets (Dolichovespa maculata (Linnaeus)). Paper wasp nests are open and cells are not covered with a cap (in an envelope).

Life Cycle: Paper wasps are semi-social insects and colonies contain three castes: workers, queens and males. Fertilized queens, which appear similar to workers, overwinter in protected habitats such as cracks and crevices in structures or under tree bark. In the spring they select a nesting site and begin to build a nest. Eggs are laid singly in cells and hatch into legless grub-like larvae that develop through several stages (instars) before pupating. Cells remain open until developing larvae pupate. Sterile worker wasps assist in building the nest, feeding young and defending the nest. A mature paper wasp nest may have 20 to 30 adults. In late summer, queens stop laying eggs and the colony soon begins to decline. In the fall, mated female offspring of the queen seek overwintering sites. The remainder of the colony does not survive the winter.

Wasps can be found on flowers, particularly from goldenrod in late fall. Paper wasp nests can be dislodged from eaves using sprays of high pressure water from a good distance, taking precautions not to allow wasps to attack nearby people or pets. Wasps will eventually abandon the nest.

Pest Status: Nests commonly occur around the home underneath eaves, in or on structures and plants; wasps attack when the nest is disturbed and each can sting repeatedly; stings typically cause localized pain and swelling, but in sensitive individuals or when many stings occur (as with most arthropod stings) whole body (systemic) effects can occur including allergic reactions that may result in death; males are incapable of stinging because the stinger on the females is a modified egg-laying structure (ovipositor) and it is not present in males; wasps feed on insects, including caterpillar pests, and thus are considered to be beneficial insects by many gardeners.
