What is one common symptom of a home affected by termites?

Swelling or buckling of wood is a common symptom of a home affected by termites because these insects feed on the cellulose found in wood. As termites tunnel through the wood, they can compromise its structural integrity, which may lead to visible deformation. The moisture they introduce can also cause the wood to warp, swell, or buckle. This physical change in the wood can serve as a significant indicator of a termite infestation, allowing homeowners to recognize that there may be an issue that requires immediate attention.

In contrast, while visible mold presence, staining on walls, and the presence of beetles may indicate other types of damage or infestation, they are not direct symptoms of termite activity. Mold is typically associated with moisture problems, wall stains may be caused by water leaks or other issues, and beetles are often a separate pest problem that does not indicate a current termite infestation.
