By extending concrete foundations at least 5-inches above the ground, subterranean termites will be unable to reach the wood or the interior of your home. When building, use termite-resistant woods like cedar, juniper, and redwood. Termites must live in a high humidity environment. By eliminating moisture, you'll prevent future problems. Remove moist soil near the foundation of your home, clean up standing water, fix plumbing leaks, and place polyethylene in crawl spaces and cracks to add a moisture barrier between the soil and your home's foundation.
Termites thrive on moldy wood.
You can prevent wood from molding by pruning back plants, bushes, and shrubbery close to your home's foundation. Seal woods which will be exposed to moisture. Using an all-weather wood sealer on patios, window frames, door frames, and at wall edges will deter termites. Cracks, crevices, broken seals, split wood and similar items should be repaired immediately. By placing a series of alarm systems around the perimeter of your property, alarms are able to monitor activity, and report any termite colonies.
