For general control... pre-construction... post construction of Subterranean Termites. Approx coverage is 250 lin. ft. Also controls wood infesting pests. Premise acts as a non-repellant. It lets the termites enter the treated area. The chemical then acts on the nervous system of the termite -- it gets confused... stops grooming itself... and is attacked by parasites and other micro-organisms that are in the soil. Also labeled for Carpenter Ants... Formosan Termites and can be used for Drywood Termite treatments!
