What kind of wood do carpenter ants prefer?

Carpenter ants have a preference for moist wood and areas that offer poor ventilation, such as attics that may be prone to dampness. This preference stems from their need for an environment conducive to the establishment of a colony. Moist wood is easier for them to excavate, and the humidity can help maintain the necessary conditions for their larvae and adults.

Moreover, damp conditions are often a sign of structural issues or decay, making such areas more appealing to carpenter ants as they can burrow into the softer, weakened wood. In contrast, dry and treated wood is less conducive to their nesting practices, as it is harder and may lack the moisture they need to thrive. Burned wood and wood devoid of cellulose do not provide suitable habitats for carpenter ants, as they are specifically adapted to consume wood with cellulose, which is essential for their diet and for the sustenance of their colonies.
