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. These termites create a series of chambers in wood, which are connected by tunnels with smooth walls, as if sandpapered.
Dampwood termites are usually found in logs, stumps, dead trees, fence posts and utility poles.
Dampwood termites do not usually infest structures because of their need for excessive moisture. However, care must be taken to avoid attracting dampwood termites to a structure, as they can cause serious property damage. In fact, dampwood termites and other termite species cause a collective $5 billion in property damage each year.
