I have been using Bulwark for 6 or 7 years in our old house and our new one. The house next to us is vacant and has been for almost a year. Recently we saw a scorpion in our house. We called Bulwark and Dustin came out right away. He treated our house inside and out, and explained things about what scorpions do, likely points of entry, and how to prevent it. Now, he makes a point of spraying the wall of the vacant house next door as that is most likely the source of our problem. All of the technicians we have had are very polite and professional. Dustin has been great. And Bulwark has been great for us.
