Some insecticides used to kill termites include soil-applied barrier treatments, such as fipronil, imidacloprid and bifenthrin, and bait systems with insecticides such as hexaflumuron and lufenuron. Fumigation by a licensed applicator with an insecticide such as sulfuryl fluoride eliminates termite infestations.
Soil-applied barrier insecticide treatments are the most common means of termite control. A properly trained and licensed pesticide applicator must apply the pesticide to achieve effective results and avoid contamination of ground water.
Bait systems are another method of termite control. These methods reduce the use of insecticide overall, relying on slow-acting insecticides that termites take back to the nest. Some of the most common insecticides in termite bait systems include insect growth regulators such as diflubenzuron and lufenuron. The first chemical registered with the EPA as a reduced-risk pesticide is a termite insecticide called hexaflumuron, which is part of a termite inspection, monitoring and control system.
Sulfuryl fluoride is a fumigant insecticide for termite control. Fumigation with insecticide in order to control termites requires expert applicators with proper training and licensing. Other methods of termite control include the application of borates to wood and other building materials during construction, as well as the use of physical barriers such as specific sizes of sand or steel mesh.
