What to Spray for Termites

There are many different products on the market to control termites. Liquid and foam products use insecticides (called termiticides) to prevent and control termite infestations.

Termiticides come in two main forms – repellents and non-repellents. Repellents redirect termites away from your home but typically do not kill them. Non-repellents contain slow-acting materials that control forager termites and nestmates through a transfer effect. The concentration and application of termiticides varies based on the location of treatment – soil or wood.

Some experts prefer to use borate products for wood treatment. Borates can spread with moisture throughout wood, ensuring deeper penetration. To prevent too much dilution, borates are not recommended for soil, where the borates can get washed away, or wood subject to repeated, prolonged soaking. Borates’ exact control method is unknown, although experts believe this material impacts termites’ digestion. Borates are low in toxicity for people, pets and the environment.

Termite control products applied to an existing home typically protect the soil perimeter around the foundation (for subterranean termites) and outer layer of wood (for subterranean and drywood termites). However, termiticides also can be injected into damaged wood. If you are building a home, discuss pre-construction termite prevention methods with your contractor and pest control expert.

How to Spray Wood and Soil for Termites
Your pest control expert can advise you on the methods and products that will provide the most effective termite prevention and control based on the termite activity and species around your home.

Professional tools are required to apply materials or spray a house – inside or out. In fact, professionals have equipment that allows them to target the termiticide application, rather than spray a larger area than is necessary. Experts may use moisture meters to determine likely areas for infestation, pressurized pumps and hoses to apply materials, and meters to check the concentration of termiticides.

Your professional will be able to explain the methods he or she recommends and answer your questions about the benefits and limitations of your termite control options.
