Subterranean termite colonies live underground. They typically enter homes at ground level or below, but they can build mud tubes to enter spots several feet above ground level.
One of the most common ways termites get in your home is through wood-to-ground contact, including doorframes, deck posts, and porch steps or supports. Subterranean termites also enter homes through cracks in the foundation and cracks in brick mortar. Sometimes, they even use the holes in concrete blocks to travel through foundation walls.
Subterranean termite prevention focuses on addressing trouble spots, such as water that pools around the foundation, and monitoring for signs of activity. Your pest control expert also may recommend monitoring stations, liquid soil treatments or direct wood treatment.
