Carpenter Ants (genus Camponotus) are large ants and are so named because of their habit of excavating, tunneling and living in wood, both indoors and outdoors. Wet or rotting wood is particularly inviting and enables easy tunneling. Always check firewood for these ants before bringing it indoors. In Maine we have the red carpenter and the black carpenter ant. Their habits and sizes are similar, but the black carpenter ant is by far the more common of the two. Carpenter ants are one of the larger ants in Maine.
The forest is the carpenter ant’s natural habitat. Any wet, rotten wood attracts a new queen. Carpenter ants infest live, dead or fallen trees wherever there is some rot and moisture. In nature, they play an important role in recycling wood, but when they attack buildings they are destructive. The closer a forest with rotten logs is to homes or buildings, the more likely is a carpenter ant infestation.
