Some species of carpenter ants are the largest ants in the North Central States. They are black or red and black. The workers range in size from 3/16 to 1/2 inch long. Colonies consist of major and minor workers. They feed on other insects, both living and dead. They also feed on meats or sweets including honeydew, syrup, honey, sugar and jelly. Carpenter ants DO NOT eat wood; they chew wood into sawdust during the process of creating galleries and tunnels. Carpenter ants nest in all types of moist or rotting wood including trees or tree stumps. They can be found indoors behind bathroom tiles and around tubs, sinks, showers and dishwashers. Carpenter ants may also be found under roofing, in attic beams, under subfloor insulation, in hollow spaces such as doors, curtain rods and wall voids and in soft polystyrene or other forms of insulation.
