Subterranean termite infestations can occur on the inside or exterior of the home. There are several telltale signs of a termite infestation. One sign is the presence of mud tubes on the exterior of the home. Mud tubes look like long tunnels made of wood and soil, which the termites construct to protect them from drying out as they travel. Other signs of a subterranean termite infestation include soft wood in the home that sounds hollow when tapped, darkening or blistering of wood structures, uneven or bubbling paint, and small piles of feces that resemble sawdust near a termite nest. Discarded wings near doors or on windowsills also indicate that swarmers have entered and infested the home.
