How do carpenter ants typically enter a building?

Carpenter ants are known for their ability to find access points into structures, and one significant way they do this is from adjacent trees. These ants often nest in decayed wood, and if a tree or shrub is sufficiently close to a building, it can serve as a bridge for them to travel into the structure. The branches can come into contact with the building, allowing carpenter ants to move easily from their nests in the trees to make their way into the home.

This behavior emphasizes the importance of maintaining a clear distance between trees and structures since it can significantly reduce the chance of an infestation. Trees that are pruned and kept at a distance from buildings can help limit access points for carpenter ants, thus preventing potential problems.

The other access points that might be considered include doors and windows, plumbing and electrical openings, and cracks in the foundation. While these are indeed potential entryways for many pests, carpenter ants primarily utilize their natural habitat and proximity to trees to gain entry, making these access points less common for them specifically.
