|Size||1/8 – 3/8 in (workers and soldiers); 1 in (swarmers)|
|Color||Workers are a pale white hue; soldiers have a similarly-colored body but with a brown head; swarmers often are dark brown or black with white/clear wings.|
|Body Structure||Workers and soldiers feature an elongated oval body with six legs and antennae. The soldier is characterized by a larger, brown head with prominent mandibles. Swarmers, also known as “primary reproductives,” feature similar bodies as workers only with wings. Unlike ants, they do not have segmented bodies.|
|Characteristics||Subterranean termites are organized by a caste system with workers, soldiers, primary reproductives/swarmers, secondary reproductives, and finally kings and queens. Termites begin the life cycle by swarming. After winged males and females mate, they shed their wings and begin a new colony, becoming the “king” and “queen.” As king and queen, they are the sole reproducers. After the queen’s eggs hatch, the offspring assume the various roles of the caste. Primary reproductives eventually leave the colony to swarm, mate and form new colonies. Wingless secondary reproductives, however, never leave the colony and are present to support the queen. Workers are sexually underdeveloped and do not mate; instead, they are in charge of building tunnels as well as feeding other castes. Soldiers handle defense of the colony, using their large mouthparts to fight off predators. Queens may live up to 50 years under ideal conditions and produce tens of thousands of eggs in her lifetime. Workers and soldiers, on the other hand, live about 1-2 years.|
|Commonly Active||Spring / Summer / Fall|
|Prevention & Treatment||If mud tubes are noted around a foundation or swarmers are spotted near your home, contact a pest control professional immediately. A trained professional will be equipped to locate the colony and tunnels and then administer proper treatment. Find out more about subterranean termite treatment and prevention options.|
Subterranean termites live in underground colonies or in moist secluded areas above ground that can contain up to 2 million members. They build distinctive “mud tubes” to gain access to food sources and to protect themselves from open air. With proper termite control, you can avoid termites finding their way into your home. Termite colonies are organized into castes depending on tasks — workers, soldiers, and reproductives.
