One of the largest ant species in the country, carpenter ants can be up to 13 mm in length. These ants are dark red or reddish black in color with wings, narrow waists, and bent antennae.
Colonies of carpenter ants often reside in moist or damaged wood; in fact, many homeowners can mistake swarms of carpenter ants for termite colonies. These colonies damage wood by excavating and creating tunnels for their nests and creating "satellite" colonies, with worker ants traveling back and forth.
Carpenter ants do not eat wood, but they will feed on sweets and meats that people leave behind. They will also feed on other insects.
Colonies of carpenter ants are usually around 15,000 workers when mature, but potentially could be over 100,000 workers.
