Liquid termiticides are a very effective way to treat a termite infestation. They act as a sort of chemical barrier and work best for subterranean termites, or timber pests. By treating the soil, the habitat of these termites is effectively destroyed and they die off.
Baiting is another very effective termite treatment. The bait is made out of cardboard, paper or another cellulose-based food that termites like. It is laced with poison then placed below ground where its slow acting poison kills the pests.
