Drywood termites house their colonies within the wood on which they feed. As they consume wood, they burrow mazes of tunnels and chambers within walls and furniture. Drywood termites leave small piles of feces that resemble pellets where they have eaten or nested. Drywood termites also cause sagging floors, walls and ceilings and may leave behind areas which appear to be water damaged. After winged drywood termites swarm, their wings shed and can be found in small piles throughout an infested home. These wings resemble fish scales.
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.
