Drywood termites are social insects. They infest dry wood, like that found in attic framing. Unlike most termite species, drywood termites do not require contact with the soil. Swarming drywood termites fly into structures and infest wood directly.
Drywood termites form colonies of up to 2,500 members. Unlike subterranean termites, drywood termite colonies do not have a worker caste. The work is done by immature termites before they reach adulthood.
Drywood termites can infest structures and cause significant structural damage. They can chew through support beams, floors and walls, causing expensive repairs.
