Where do carpenter ants prefer to nest?

Carpenter ants prefer to nest in moist wood because it is easier for them to excavate and form their colonies. Moist wood typically shows signs of decay and is softer, which allows the ants to tunnel through it more easily than dry wood. This preference for damp environments is often linked to their need for water; they are typically found in areas where there is moisture present, such as near leaky roofs, water pipes, or rotting tree stumps. This nesting behavior also makes them an indicator of potential moisture issues in structures, which can lead to further wood damage or pest problems. Other options do not align with their nesting habits; for instance, while they can occasionally be found in soil or dry wood, these do not provide the conducive environment that moist wood does for their nesting needs. Empty containers lack the structural integrity and moisture content that carpenter ants seek for their colonies.
