Years ago, the technique used for treatments was a spray because they were the products available. Now with the advancement of products, we rarely use liquid treatments. Most pests are controlled by baits, gels and granules. Our goal is to establish an exterior barrier so we do not have to inconvenience you each time to do an interior service. If you are seeing pests inside, we will be glad to provide an interior treatment at no additional cost. Most of our customers are happy with exterior treatments once that barrier is established.
