What is a common sign of termite infestation in a structure?

A common sign of termite infestation in a structure is hollow-sounding wood. This occurs because termites feed on the cellulose material within wood, creating hollow channels and chambers as they consume it. As the wood becomes more compromised, tapping or knocking on infested wood can produce a distinct sound that indicates the presence of termites.

Identifying hollow-sounding wood is crucial for pest control technicians because it helps them determine areas that may require further inspection or treatment. It indicates not only the presence of termites but also the level of damage that has been done, which is essential for deciding the best remediation approach.

Other signs such as excessive mold growth, bubbling paint, or increased indoor humidity are not definitive indicators of a termite infestation. While these could suggest other issues in a building, they do not specifically signal the presence of termites and can result from various environmental factors or different types of pests. Understanding these distinctions is important for effective pest identification and control strategies.
