As the name suggests, dampwood termites infest wood with a high moisture content. Dampwood termites are normally larger than other termite species. Bodies of king and queen dampwood termites range in size from ½ inch to ⁵⁄₈ inch long and have two pairs of wings that are equal in size and shape, extending beyond their abdomen. Nymphs can be as long as ⁵⁄₈ inch and worker dampwood termites are up to ¾ inch in size.
Dampwood termite colonies, like drywood termites, have no worker caste. The nymph dampwood termites take care of the kings and queens of the colony and feed the soldier caste. Drywood termites are usually found in logs, stumps, dead trees, fence posts and utility poles.
Because of their need for excessive moisture, dampwood termites are not often found in structures. However, these termites will infest sound wood if moisture is maintained, especially where wood is in contact with the ground or there is a moisture supply such as a leaky pipe. Care must be taken to avoid attracting dampwood termites to a structure as they can cause serious property damage.
