What is a common sign of termite activity in a home?

A common sign of termite activity in a home is hollow-sounding wood. This phenomenon occurs because termites feed on the cellulose within the wood, effectively hollowing it out from the inside. When you tap on a piece of wood that has been infested, it may produce a hollow sound as there is less solid material inside due to the feeding habits of the termites. This sound is often an indicator that there is significant damage occurring within the structure of the wood, which can lead to more severe structural issues if left unaddressed.

In contrast, while bubbling paint can indicate moisture issues, it doesn't specifically signify termite activity. Water stains are typically associated with leaks or humidity problems, which also do not directly relate to termites. Drafts are indicative of gaps or a lack of insulation, signaling potential air leakage, rather than insect infestation. Thus, hollow-sounding wood is a more direct and specific symptom of termite presence in a property.
