Seems archaic to dig trenches around structures to dispense termidor. Why not ram PVC into the ground every 12 inches and pour it down that way? It's consistent with the drilling method used by pros on foundations.
While you are correct in that injecting termiticide into the ground seems more consistent with how professionals treat with Termidor SC and similar products, keep in mind that they are also using truck-mounted power sprayers with very high pressure to forcefully inject the product into the ground. While trenching may be laborious, it is actually a better treatment because you are creating a continuous barrier around the structure rather than creating spots of injection. We always recommend trenching except where spaced applications are needed due to drilling in concrete around the home. You are still using 4 gallons of solution per 10 linear feet, regardless of how it's applied, and the product needs to be at least 6 inches into the soil. Keep in mind, too, that a proper treatment with Termidor is good for at least 10 years. Termite Prevention Article
