| Drywood termites are social insects that live in colonies. The colonies are composed of kings, queens and soldiers. There is no worker caste as in subterranean colonies. The work is performed by immature termites before they become adults. King and queen termites perform the reproductive functions of the colony. They are light to dark brown and 1/3- to 3/8-inch in length. Soldiers guard the colony against invaders such as ants. They are pale, cream colored and wingless with large brownish heads and jaws. The nymphs (immatures), which are the most numerous caste, are pale, cream colored and wingless. The soldiers and immatures remain inside the wood at all times. |
