Most Common Termites in Tennessee
Subterranean termites occur trough out Tennessee and are kind that most commonly infest a structure. These termites have strict moisture needs and therefore nest in the soil and forage underground. They can attack any untreated woods in contact with the soil. These organisms create mud tubes within the cracks of foundation or over the outside of the concrete. They travel through these tubes and can reach wood several feet above the ground.
Formosan termites are more aggressive feeder than native subterranean termites. They originated from the far east, probably hitchhiking to the US in carted material following WWII. Unlike the other subterranean termites that eat along the grain of the wood, the Formosan termite is less discriminating and will often hollow out a tree trunk or wooden beam. It is estimated that a Formosan termite colony can consume wood about SIX TIMES as fast as an eastern subterranean termite colony.
Drywood termites can rarely be found in Tennessee. And when we do, usually their origin can be traced from furniture or other wood moved into Tennessee from tropical countries or southern regions of the US. Drywood Termites attack wood directly. They require very little moisture, so they live within the wood and have no connection to the soil. As they feed, they cut across the grain of wood, excavating large galleries connected by small tunnels.
