Most ant infestations that appear inside a home have their colony outside or underneath it — often in the crawlspace.
Carpenter ants, the most common structural pest in the Pacific Northwest, don't eat wood. They excavate it to build nesting galleries. A mature carpenter ant colony can hold 3,000 workers, and satellite colonies split off to establish new nests nearby. They target wood softened by moisture first: crawlspace beams, sill plates, and floor joists.
By the time you see carpenter ants inside, a colony is already close enough to be sending workers in regularly. Sound Pest Management's crawlspace inspection finds where they're nesting, how they're getting in, and what stops them at the source.
