Sometimes called “powderpost” termites or “furniture” termites, due to their small fecal droppings and the fact that they commonly attack timber furniture, Cryptotermes drywood termites are typically found in the humid coastal areas; of the southern United States. Incidents involving this species of termites, have been reported from Virginia to Florida, through the desert southwest, and along the Pacific coast. Cryptotermes drywood termites are sometimes discovered in other states, after being transported in wooden furniture, or other such timbers.
Interestingly, the average moisture content of seasoned timbers commonly used in the United States is 8-12 percent, and this species of termites prefer to infest the structural timbers of buildings, furniture (or other dry timbers); that have less than 12 percent timber moisture content. In this ideal environment, Cryptotermes drywood termites will eat across the wood grain, constructing elaborate chambers or galleries; connected by endless tunnels.
Because these termite colonies are located in the wood they eat and are often small in size, perhaps containing a few thousand termites, it is commonplace to have multiple colonies; causing a pest control problem in the same building. Furthermore, this termite species colony requires no contact with the ground, and can obtain their required moisture intake; from the timber they infest.
