General Information About Wood Destroying Insects: Termites - Termites are tough, determined, and highly efficient. And chances are you'll see no evidence of their work until structural damage has been done. Subterranean termites, the most common kind, live in colonies in the soil, from just below the surface to as much as 12 feet down. Each colony is built around a King and a Queen,whose sole job is reproduction. Worker Termites " commute " in what appears to be a mud tunnel between the colony and sources of food, including wood fibers and other forms of cellulose. These Workers rarely break through the surface of wood instead they hollow it out from the inside making it difficult to detect. Carpenter Ants - Are chiefly a cosmetic nuisance. They nest in wood already softened by decay and emerge to forage for food. These Ants must emerge from their nest to forage, making them selves very visible. They are among the largest ants in the United States, worker ants varying in size between 1/4 to 1/2 inch long. They are black or black with a reddish brown midsection.
