Shape and size:
Carpenter ants are approximately 10mm in body length and are typically dark brown or black in color. Unlike some ant species with uneven thoraxes (upper body area), when viewed from the side, a carpenter ant’s thorax looks evenly rounded.
Signs of a Carpenter Ant infestation:
Carpenter ants are capable of causing structural damage to homes. They reside both indoors and outdoors in moist, decaying or hollow wood. They carve “galleries” into the wood grain to provide passageways for movement within the nest, leaving behind what looks like sawdust.
