Dampwood termites constitute a small and rather primitive family Termopsidae (Latin) of termites (Isoptera). They contain four or five extant genera with 13–20 living species, but can be divided into several subfamilies. They may be a nuisance, but compared to the drywood termites (Kalotermitidae), usually do not cause extensive damage to buildings or other man-made structures. As their name implies, they eat wood that is not dried out, perhaps even rotting, and consequently of little use to humans.
To avoid dampwood termites, homeowners should eliminate sources of moisture by diverting water away from the home's foundation. It's important to repair leaking faucets, water pipes and AC units on the outside of the home as dampwood termites are often drawn to these areas. Firewood should be stored at least 20 feet away from the house. To prevent dampwood termites indoors, reduce humidity by properly ventilating crawl spaces, attics and basements.
