Treating the soil beneath the building and around foundations when it is still in the process of construction is a good way to prevent termite infestation. Pre-construction anti-termite treatment is attracting attention throughout the world. The soil in immediate contact with the foundation and floor structure of a building is treated with an insecticide that kills or repels termites thus forming a toxic barrier that is lethal to termite entry. Pre-construction anti-termite treatment is done in the early stages of construction so as to prevent termite infestation in the constructed building.
