Is it a pest in the house?

Paper wasps are not very defensive but can become a nuisance when they build nests over doorways or near fruit trees.

Does it bite or sting?

Males cannot sting; workers and queens can sting, which usually hurts briefly but may cause severe allergic reactions in some people.

How to get rid of it

Knocking down new nests early in the season forces the founding female to relocate, and insecticide sprays labeled for wasps can be used carefully.

How this page works

This is one bug's fact sheet. The colored box at the top says whether it is dangerous. Sections below cover how to recognize it, whether it is a pest, and how to deal with it. The US map shows which states have records; tap a state to see other bugs there.

Every fact on Bug FAQ comes from a named source (university extension sites, government agencies, GBIF, iNaturalist, Wikipedia). The source is linked next to each section. If we have no source for something, we leave it out.
