Carpenter ants are large ants (1/4 in–1 in) indigenous to many parts of the world. They prefer dead, damp wood in which to build nests. Sometimes carpenter ants will hollow out sections of trees. The most likely species to be infesting a house is the Black carpenter ant, Camponotus pennsylvanicus. However, there are over a thousand other species in the genus Camponotus.

Carpenter ants reside both outdoors and indoors in moist, decaying or hollow wood. They cut "galleries" into the wood grain to provide passageways for movement from section to section of the nest. They can leave "sawdust" behind that provides clues to nesting location. If this wooden complex happens to be a wall frame within your home, structural damage may result. Moisture is the key component to look for, when managing this species.
