When inspecting for signs of subterranean termites, what area should be a focus?

Focusing on basements and crawl spaces is essential when inspecting for signs of subterranean termites because these areas are typically close to the ground where termites live and thrive. Subterranean termites require moisture and are often found in the soil next to the foundation of buildings, making basements and crawl spaces prime locations for their activity.

In these areas, inspectors should look for mud tubes, which are used by termites to travel from the ground to their food sources, as well as signs of wood damage and frass (termite droppings). Given that subterranean termites typically nest underground, their activity is also generally first noticed in places that are in direct contact with or near the soil.

While exterior walls may show signs of infestation, the likelihood of being able to trace the source back to subterranean activity is reduced compared to inspecting below ground. Upper floors and attics are located far from the ground where termites are active and are less likely to be where initial infestations start. Thus, basements and crawl spaces are critical areas to examine for detecting subterranean termite presence and preventing further damage.
