No. Preventive Pest Control provides the best pest control service available, and our goal is to provide you with a pest-free environment. However, pests can enter your house in grocery bags, on pets, or through the air. In addition, pests are usually area/neighborhood problems; so even though we are treating your home, pests from the surrounding area can walk, crawl, or fly onto your property and attempt to enter your home. In fact, when we treat your home the insects will be flushed out of their hiding places so you may see more pests than usual immediately after we treat your home initially. We ask that you allow 2-3 weeks for the treatment to take effect. If you are still seeing an inordinate number of pests, give us a call and we will re-service your home free of charge. By servicing your home on a regular basis, we guarantee that we will provide you with such a high level of service that you will be satisfied. If for some reason you are not satisfied, we will return and service your home free of charge.
