Where do carpenter ants typically nest?

Carpenter ants are known for their nesting habits, which primarily involve creating colonies in wood that is either decayed or has some level of moisture. One common location for these nests is in tree stumps where the wood is often softer and easier for the ants to excavate. Additionally, carpenter ants may also establish their nests within hollow doors, particularly those made of wood, as they can easily access the core material.

This choice highlights the affinity of carpenter ants for nesting in materials that allow them to tunnel and create their extensive colonies. Their preference for decayed wood indicates that they often seek out sites where the wood is already compromised, making the process of tunneling much easier. This behavior is a key characteristic that distinguishes them from other types of ants that may nest in more typical underground locations or soil.
