The Damage that can be created by carpenter ants can be expensive when not caught in time. Carpenter ants love wet and moldy types of wood and usually do their damage after you have noticed them.
They have a waist with one node (petiole) and a thorax (area behind the head) that is evenly rounded when viewed from the side.
Workers are black or red and black.
Workers range in size from 3/8 to 1/2 inch long; one type of carpenter ant is only 3/16 inch. Even carpenter ant workers from the same nest vary in size. Queens and males are larger than workers and have wings. Queens will lose their wings when starting a new nest. Queens have been known to grow as large as one inch in width.
