Venebles is locally owned and operated. Chances are an actual Veneble will come to your home or place of work to check out your critter problem. They are knowlegable about all things that infest. They use the critters' behavior against them to minimize any chemicals used. They won't put themselves "on retainer" to come spray poison on your house every month because once they've done their job, the critters are gone and you and your house are happy and healthy!
