Which common household pest is known to cause structural damage?

Termites are well-known for causing significant structural damage to buildings and other wooden structures. This is primarily due to their diet, which consists of cellulose found in wood, paper, and other plant materials. When termites infest a property, they can tunnel through wood, compromising the structural integrity of floors, walls, and support beams over time.

In contrast, while roaches, ants, and bed bugs can be nuisances and affect hygiene, they do not typically cause structural damage. Roaches may contaminate food and spread disease, ants can invade homes in search of food but do not damage structures, and bed bugs are primarily a concern for infestations affecting sleep and comfort rather than structural integrity. Thus, termites are distinctly recognized by their destructive feeding habits, making them the correct choice for a pest known to cause structural damage.
