When subterranean termites are found in a home, what issue is typically suspected?

When subterranean termites are found in a home, the primary issue that is typically suspected is a moisture problem. Subterranean termites are attracted to areas with high moisture levels because they require water for survival and to aid in the digesting of cellulose from wood. The presence of these termites often indicates that there is an underlying issue related to excess moisture, such as leaky pipes, improper drainage, or other sources of moisture that can lead to wood deterioration.

Identifying a moisture problem is crucial because it not only contributes to termite activity but can also lead to significant damage to the home's structure if not addressed. A home that has an environment conducive to moisture will likely see an increase in termite populations, as they thrive in such conditions.

In contrast, while a pest infestation and structural problems can be consequences of termite presence, they are not typically the primary reason for their occurrence. Ventilation issues can contribute to a moisture problem but do not directly relate to the attraction of subterranean termites. Therefore, focusing on addressing moisture problems is essential when dealing with subterranean termite infestations.
