Which termite type is noted for having an average colony size of over 1000?

Subterranean termites are noted for having an average colony size of over 1000, which distinguishes them from other types of termites. These termites typically establish large colonies within their underground nests, where they can grow significantly in numbers, often exceeding thousands of individuals. This large colony size gives them a robust social structure and enhances their ability to find food and spread, making them particularly concerning for property damage.

In contrast, dampwood and drywood termites typically have smaller colony sizes. Dampwood termites thrive in moist wood and do not form large colonies since they often reside in isolated pieces of wood with sufficient moisture. Drywood termites also tend to occupy smaller colonies, usually only a few hundred to a few thousand individuals, as they live inside the wood they infest rather than creating extensive tunnel systems like subterranean termites. Therefore, while all termite types are important in their own right, the size of the subterranean termite colonies sets them apart significantly.
