Facts:

Subterranean termites build distinctive tunnels, often referred to as "mud tubes," to reach food sources and protect themselves from open air. They use their scissor-like jaws to eat wood 24 hours a day, seven days a week. Like other termite species, subterranean termites also feed on products containing cellulose. Subterranean termites swarm in the spring when groups of reproductive termites go off to start new colonies. Termites may be tiny, but they can cause huge damage to your house should you experience an infestation. According to the National Pest Management Association (NPMA), these pesky critters cost U.S. homeowners an estimated $5 billion a year to control and repair damage.
