Termites, wood-destroying insects, can be a major problem in garages. Subterranean termites nest in the soil and build mud tubes to reach wood, while drywood termites infest wood directly and dampwood termites prefer moist wood. Termites damage wood by consuming its cellulose, weakening structures and causing costly repairs. Effective termite control involves both prevention (moisture control, inspections) and treatment (chemical treatments, baiting systems). Prompt action is crucial to minimize damage and protect property value.
