Termites Combine methods such as modifying habitats, excluding termites from the building, and using mechanical and chemical methods to destroy existing colonies. Physical Control Reduce the moisture level of the wood. Eliminate direct contact between wood and soil. Install termite shields to prevent termite entry through masonry walls. Remove tree stumps and wood debris.
Plant trees away from the building.
Install a sand barrier to exclude subterranean termite attacks. Seal and screen holes, cracks and crevices to prevent termite entry. Install sand barriers in the crawl spaces near perimeter foundations and under new slab foundations during construction. Treat vulnerable wood with borate-based products. Spot-treat wood with termiticides such as fenvalerate and methoprene.
