This is one of two major drywood termites in the United States, and its range is from South Carolina to Florida and west to Texas. There is no true worker caste, as the nymphs perform the labor and all eventually grow to either soldiers or alates. Winged adults will not be produced until the colony is at least 4 years old, and mature colonies usually have less than 3000 members. Swarming may be during the evening or at mid-day, varying with location, and often only a dozen or so alates will swarm. Further evidence of infestation is the presence of fecal pellets on surfaces, having been pushed out of the galleries by the workers. Colonies may be over 2 years old before this evidence is seen.
Control is by either fumigation of structures or infested objects, or by injection of a residual insecticide into the galleries in the wood. Consideration must be given to the small colony size, and the possibility that multiple colonies may exist within a single structure. Alternative treatments methods other than fumigants are becoming more widely used.
