Most all Termite problems we have here in the Valley are subterranean. That means that the colony lives underground and attacks the home by building mud tubes into the structure. For this reason most of the treatment for these termites is done by injection or drenching into the soil areas around the home. This process develops a barrier of treatment that when done with an excellent product (such as Termidor SC) provides a protection by killing off the colony as they build up from the ground.
