Carpenter ants (Camponotus spp.), also known as sugar ants, are large (0.3 to 1.0 in or 0.76 to 2.54 cm) ants indigenous to many forested parts of the world.They build nests inside wood consisting of galleries chewed out with their mandibles, preferably in dead, damp wood. They do not consume the wood, however, unlike termites. Sometimes, carpenter ants hollow out sections of trees.
