Drywood termites are usually found in warm, southern climates, while subterranean termites are found throughout the continental United States. Subterranean termites build their colonies underground and can travel above ground to access sources of food. They enter homes through cracked or unsealed foundations, as well as through tunnels constructed from mud, their feces and saliva. These tunnels are brown, dry and cylindrical in appearance. The presence of these tunnels near the foundation of your home is a sure sign of subterranean termite infestation. Just like drywood termites, subterranean termites produce winged swarmers which indicate an active termite colony.

Homes constructed primarily of wood are not the only structures threatened by termite activity. Homes made from other materials may also host termite infestations, as these insects are capable of traversing through plaster, metal siding and more. Termites then feed on cabinets, floors, ceilings and wooden furniture within these homes.
