Which statement best describes signs of a carpenter ant problem?

• A. Only moisture sources
• B. Only nests locations
• C. Neither
• D. Both moisture sources and nests

Answer: (D)

Carpenter ants need damp, decayed wood to establish nests, so signs often come from two related clues: moisture problems and actual nest locations. Moisture sources point you to where wood has become soft or damaged, which is where ants are likely to dig galleries. Nest sites reveal where colonies are living—inside hollowed wood, behind walls, in voids, or within structural components. Seeing both a moisture issue and a nest location strongly indicates a carpenter ant problem, more so than either clue alone. You might also notice frass (wood shavings with insect bits) and, in certain seasons, winged reproductives, which further support the presence of an active colony.
