Like termites, New York City and New Jersey carpenter ants swarm in the late spring to expand their colonies. When carpenter ant colonies reach maturity, specialized winged reproductives are produced. Flying off in mating pairs, carpenter ants bite off their wings when they land and crawl off to establish new colonies. Carpenter ants are such poor fliers, reproductives don’t go far, often landing on the same commercial property. Multiple carpenter ant colonies may be located in close proximity, multiplying the amount of damage these wood-destroying insects can do to commercial structures.
Unlike termites, carpenter ants do not ingest wood, they hollow out large galleries in foundation timbers, building trim and wooden structures to house their massive nests and nurseries. Frass, the sawdust-like by-product of their excavation activity, is sometimes found where carpenter ants are active. More often the ants themselves are spotted as they forage for food.
The largest ant species in New York and New Jersey, carpenter ants are typically black and grow to 5/8 inch long. Due to the prodigious numbers, a colony of carpenter ants can cause considerable structural damage to commercial buildings over time. In fact, carpenter ants can be expected to attack 1 in 4 New York and New Jersey buildings. If you notice large black ants in or around your property, you have carpenter ants.
