Ants are social insects living in large communities where they depend upon each other for the survival of the entire colony. Ant colonies generally form nests where they store food, lay eggs, and maintain nurseries. There can be tens of thousands of ants in a single colony and several colonies inhabiting any part of your home, cottage or business. The main ants to invade homes and buildings are: Carpenter Ants, Odorous House Ants and Pavement Ants. Carpenter ants are particularly destructive as the chew wood and other materials to make nesting materials.
