Arizona Termite Licensing Practice Exam: Free Practice Test & Study Guide

Drywood termite colonies have the ability to establish themselves above ground, which is a defining characteristic that differentiates them from other types of termites, such as subterranean termites. Unlike subterranean species that typically build their colonies deep in the soil, drywood termites infest and live within the wood they consume, making it possible for them to create colonies in wooden structures, furniture, and even trees.

This adaptability is significant because it allows drywood termite colonies to thrive in environments where they have access to their food source without requiring contact with the soil. By residing in the wood itself, they can remain undetected until significant damage occurs, complicating detection and treatment.

The other statements do not accurately describe the behavior of drywood termites. They do not primarily live underground; in fact, they are commonly found in dry, sound wood rather than in old wood exclusively, and while they do have a caste system, the worker caste is not present in the same way as in subterranean termite species. Instead, drywood termites may have a reproductive caste and soldiers, but they lack the distinct worker caste seen in other termite types.
