What is a common sign of termite presence in a building?

A common sign of termite presence in a building is the presence of sawdust or wood shavings. Termites, particularly the Drywood variety, consume wood and produce frass, which is essentially their excrement and resembles sawdust. This frass is typically found near wood structures that have been infested. When termites eat through wood, they leave behind these small wood particles, indicating their presence and activity. Recognizing this sign is crucial for early detection and treatment of termite infestations, which can cause significant structural damage if not addressed promptly.

Other signs of termite activity may include mud tubes on exterior walls or visible damage to wood, but sawdust or wood shavings are often one of the more visible and direct indicators that an infestation is occurring.
