BIOLOGY
Termites are social insects with a caste system and division of labor, care of young and overlapping generations. Colonies may contain hundreds of individuals. Reproductive males and females (alates) are initially winged. They swarm to locate new colony sites, mate and lay eggs. Swarming mostly occurs in the late afternoon. Pseudergates (false workers) feed, build living space and care for the young. Soldiers defend the colony and have larger, defensive mandibles.
Food
Wood with little water content. Wood may be in use by humans or in nature.
Habitat
Drywood Termites prefer the warmer regions of the Bay Area and are found far less often in areas where there is morning fog.
Active Period
Active year-round. Swarming occurs from late September through November.
Nesting
They live in wood that has little water content, including wood that is warmed and in direct sunlight. They infest dry wood in structures or dry parts of trees, including living trees.
Importance
Drywood Termites do not seek water, but produce water through their own metabolism.
Distribution
California, Washington, Utah and Arizona. However, infestations have occurerd in many other states and Canada and China. The species is well-established in Japan.

HABITAT
