Subterranean termites are native to every state except Alaska. A colony may include up to several million individuals, living as deep as 20 feet underground. Feeding on cellulose-based material, such as wood, termites find human dwellings offer the ideal combination of warmth, moisture and food. The Queen occupies a "royal cell" with the King. She may live up to 30 years, laying many thousands of eggs annually. Supplementary Reproductives act as replacements for the Queen if she should die. They may also produce eggs even if the Queen is healthy to help increase colony size. Soldiers with armored heads and strong jaws, protect the colony from enemies, most commonly ants. Winged Reproductives are the termites you may see when they "swarm", usually in the spring signaling a well-developed colony. After shedding their wings, reproductives pair off, burrow into the soil and begin a new colony. Workers represent most of the termites in a colony. Blind and sterile, they forage for the colony's food. Most damage is caused by worker termites.
