Carpenter Ants are larger than other species of ants, but cannot be distinguished by size alone. Carpenter Ants have 6 legs, a “waist” and 3 separate body regions.
Carpenter Ants can also be identified by where they choose to nest. They like decayed wood, as it offers the right temperature and humidity. They often build colonies under the cloche of a smooth surface or even a pile of wood. Their colonies can go unnoticed and cause serious structural damage. Although, Carpenter Ants do not eat wood; they excavate it to create tunnels.
