Carpenter ants get their name from their habit of building nests in wood. Unlike termites, they do not feed upon wood but merely use it as a place to nest. They will build their nests in human structures and may cause significant structural damage. Five species of carpenter ants occur in Missouri: Camponotus pennsylvanicus, Camponotus castaneus, Camponotus ferrugineus, Camponotus nearcticus and Camponotus sayi. Carpenter ants are recognized by their characteristic evenly rounded thorax when viewed from the side.
