Typically, any preventive pest maintenance program that we perform for you is completely warrantied. If, at any time prior to a regularly scheduled service call, an infestation of pests covered in your agreement occurs, we will provide the service needed to control these pests at no additional charge. On top of that, if our pest protection service does not achieve the results we promised, we will refund the amount you paid for the unsatisfactory service call. Now that takes confidence.
