Exterior perimeter termite treatment may be an option if your home is at risk of a subterranean termite infestation. The treatment focuses on treating areas adjacent to the exterior foundation wall with chemical repellents. The goal is to repel termites before they have a chance to make direct contact with the home.
Many homeowners prefer this type of treatment over a conventional chemical barrier because it requires less drilling into their slabs or foundation walls. It may also require less overall repellent depending on the specific home. Exterior perimeter treatments may be used in conjunction with localized interior treatments if subterranean termites are discovered inside the home.
