Which type of termites make nests by boring into wood?

The correct answer, Drywood Termites, are known for their unique nesting behavior, which involves boring into and living inside the wood they infest. Unlike other types of termites, Drywood Termites do not require contact with the soil and can establish colonies directly within the wooden structures they consume. This capability allows them to thrive in dry, solid wood, making them somewhat less dependent on moisture compared to other termite species. Their presence is often identified by the frass or droppings they produce, which can accumulate at entry points in the timber.

Subterranean Termites, on the other hand, typically build their nests in the soil and may create mud tubes to access wood above ground. Dampwood Termites are associated with decaying wood that contains a higher moisture content and do not usually bore into dry wood. Powderpost Beetles, while wood-boring pests, are not termites but beetles that produce small holes in wood as they emerge, rather than establishing nests within the wood itself. Thus, Drywood Termites are distinguished by their inherent ability to form colonies inside the wood they infest, leading to their classification as the correct answer to this question.
