What is a common symptom of termite infestation?

A common symptom of termite infestation is the presence of mud tubes along foundation walls. These tubes are constructed by subterranean termites as they travel between their underground nests and their food sources, which often include wooden structures of a home. The mud tubes serve to protect the termites from predators and dehydration as they move above ground. They are typically found in areas that are conducive to moisture, which is essential for the survival of these pests.

Identifying mud tubes is crucial for early detection of a termite problem. Once termites have created these tubes, it indicates an established colony nearby that may be damaging the structural integrity of the building. Recognizing such signs can help homeowners take appropriate preventative actions or seek professional pest control assistance.

The other symptoms listed may not necessarily indicate a termite infestation specifically. For example, visible insects flying indoors can indicate various pest issues, including carpenter ants or other types of insects. Odd smells in the basement typically suggest moisture-related problems or mold, rather than directly indicating termites. Piles of dust around furniture are more suggestive of other insects like carpenter ants or powderpost beetles rather than termites. Thus, mud tubes are a clear and specific sign of termite activity.
