For Pre-Construction: Residual Chemical is applied at the soil layer before the building or structure is built on it.The soil treatment process involves applying a liquid insecticide to the soil around the perimeter of the structure or at strategic points around the foundation. The insecticide will then soak into the soil and form a chemical barrier that will kill any subterranean pests that come into contact with it. The chemicals used in soil treatments are designed to be long-lasting, providing protection for several years.
