What is perimeter pest control

One service we get asked alot of questions about is perimeter pest control. Perimeter pest control is a program that creates a barrier around the exterior foundation of your home to prevent insect pests from invading. 3 applications are made during the year, which are spaced out 8-10 weeks apart. The barrier is applicated in the mulch bed and up the house foundation approximately 2′. The barrier is also sprayed in window wells and across thresholds. We have gotten great feedback on the success of this program of limiting pests such as ants, spiders, etc. This treatment does not effect any interior pests, but solely stops outside pests from coming in.
