A nesting of carpenter ants inside a building typically suggests what type of problem?

Temperature
Moisture
Structural
Ventilation

The correct answer is: Moisture

When carpenter ants nest inside a building, it is an indication of a moisture problem. Carpenter ants are attracted to wood that has been compromised by water damage, as they are primarily seeking out a suitable environment for nesting. They do not actually consume the wood as termites do but rather excavate it to create their nests. This behavior often indicates that there is a source of moisture present, either due to leaks, high humidity, or other water issues. Moisture both promotes the decay of wood, making it easier for carpenter ants to tunnel and nest within it, and attracts them due to the favorable conditions it creates for their survival and reproduction. Addressing the moisture issues is crucial not only for resolving the immediate concern of carpenter ant infestations but also for preventing future wood damage and structural integrity concerns.
