What type of wood do Carpenter Ants generally prefer for nesting?

Carpenter ants typically prefer moist, soft wood for nesting because this type of wood is easier for them to excavate. They seek out wood that is already decayed or has high moisture content, which not only facilitates their nest-building activities but also provides a suitable environment for the colony. The preference for moist, soft wood often leads them to infest areas of a structure that are prone to water damage or deterioration, such as locations near leaks or areas with high humidity. This behavior highlights the importance of addressing water issues in structures to prevent carpenter ant infestations, as they are less likely to nest in dry, hard woods where they would face more difficulty in creating their tunnels. In contrast, while dry hardwood and seasoned pine may be used for other purposes or by other species, they are not the primary nesting materials for carpenter ants, making the choice of moist, soft wood the correct answer in this context.
