The North Carolina Official Waiver of Minimum Requirements for the Control of Subterranean Termites in Existing Structures is a standard form prescribed by the NC Structural Pest Control Committee. This form permits the licensee to deviate from or omit one or more of the minimum subterranean treatment requirements. For example, a waiver may be necessary because the working clearance in the crawlspace is inadequate for it to be treated properly, or a treatment requires indoor drilling that may not be desirable. This latter situation usually occurs with slab construction, where holes must be drilled through the floor or the floor must be removed in order to drill the slab and treat the soil beneath it. Any part of the treatment that is waived must be properly explained on the standard waiver form.
Conclusion Remember the best method for the control of subterranean termites is prevention.
