Controlling Termites

Subterranean termites are the most widespread and destructive termite group in North America. They are so-named because they excavate through the soil to reach wood in contact with the ground. To reach material above ground, they either move through connecting wood, or through earthen “shelter tubes” that they build over concrete, masonry, or other materials. Given the choice, subterranean termites will usually access aboveground wood through protected cracks and cavities, such as in concrete slabs and foundations. Subterranean termites normally return to the soil periodically for moisture. However, if the moisture content of wood above ground level is high enough, they can survive and multiply indefinitely with no ground contact. Eliminating conditions favorable to termites is an essential first step
