Hi-Yield 38-Plus Insect Control - 38% Permethrin is labeled for subterranean termites. However, a more effective method would be to do a trench around the perimeter of your home as it will only kill the termites that contact the treated soil. We recommend that you use a non-repellent product such as Termidor SC for a termite barrier. Termidor SC is the top termite product on the market. Termidor is completely undetectable by termites and once termites touch it they contact, ingest and spread the termiticide until it eliminates the entire colony. It will last 10 years or more in the soil. For more information on termite treatments, please read our 'How to Perform a Termite Treament Article'.
