Exterminating roaches is a process. Roaches are naturally occurring in our environment, and therefore, keeping the inside of your home free from an insect that is naturally on the outside of your home will take constant vigilance. The best protection is a barrier treatment around the doors, windows, and base of the home, thereby creating a “barrier” that roaches will need to pass to get into your home. This barrier will eliminate them before they can create a nest in the home.
