What is a common sign of a termite infestation?

A common sign of a termite infestation is the presence of mud tubes, wood damage, or discarded wings. Termites are known for creating mud tubes as a protective pathway from their colony to sources of food, usually wood. These tubes safeguard them from open air and predators.

Wood damage is another significant indicator, as termites feed on wood and can cause substantial structural damage over time. The presence of discarded wings suggests that a swarm of termites has occurred, usually indicating reproduction and the potential establishment of new colonies. This combination of signs is critical for pest control professionals in identifying and confirming a termite infestation, making it a key aspect of termite detection and management.

In contrast, other options present symptoms that do not specifically point to termite infestations. Pencil-sized holes may be indicative of other pests, unusual noises could relate to various sources within a home, and foul smells may arise from numerous causes including mold or decaying organic matter, none of which are uniquely associated with termites.
