Of all the species of termite in America, subterranean termites are typically the most destructive. In nature, subterranean termites are beneficial, as they break down dead trees and other woody materials that would otherwise accumulate.
These termites live in colonies composed of workers, soldiers and reproductives. The workers, which are about 1/8 inch long, are the most common in the colony. Soldiers defend the colony against other insects, such as ants. Winged reproductives are responsible for mating, and pairs of these termites form new colonies.
