Termites are social insects that live in colonies. Each termite colony divides its members into three castes — workers, soldiers, and reproductives. Worker termites are the largest caste; they help build and maintain the nest, care for the young, and forage for food. Soldiers protect the nest and help with nest maintenance.
Reproductive termites produce more colony members. When a termite colony has matured, winged reproductive (termite swarmers) emerge from the nest to find a mate and a suitable location to build a new nest.
Here in our region of California, we need to guard our homes against two kinds of termites; subterranean termites and drywood termites.
Subterranean termites have high moisture needs and like to feed on wet or decaying wood. These termites nest in areas of damp soil and travel to their found food sources daily. Subterranean termite colonies are large and contain hundreds of thousands of members, and they are the most common species living across the United States.
On the other hand, drywood termites live together in smaller colonies with numbers in the hundreds or thousands. Drywood termites are very efficient feeders and nest within the wood they feed on. These termites have low moisture needs and invade dry, sound pieces of wood.
