Drywood termites can be more difficult to detect (as compared to subterranean termites) and aren't typically noticeable until small piles of pellets (their feces) collect. Drywood termites make their nests within the wood they consume and oftentimes infest walls and furniture. They require no soil contact and get their moisture from the wood. They also attack floors, furniture and books. When a colony has matured, winged, swarming termites can be seen around windows and doors. Winged termites are highly attracted to sources of light and are most active in springtime. After mating, these termites locate a new breeding site and create another colony, spreading infestations throughout multiple locations. If a Drywood termite infestation is suspected in your house, a pest control operator should conduct a thorough examination of the entire structure.
