How deep should the trench be for an outside Termidor treatment?

The basement is five feet below the grade level, and I believe on the slab. I found active termites in the basement, they are very close to the walk out door frame and in the nearby side wall. How deep should the trench be for an outside Termidor SC treatment?


The trench around the exterior of the house only needs to be 6 inches deep.  It is not realistic to dig a 5 foot deep trench and no company would do this either.  On the inside of the basement, it would probably be a good idea to drill through the slab of the basement along the wall that is below grade and apply Termidor SC through the slab and/or treat the termites directly in the wall where the activity is.
