Alterra has (so far) been a great company to sign up with. The sales rep was very helpful and we were able to sign up for a really good deal. Two guys came over the following day to spray our home and we were very satisfied with their job. The best part about their service is that they offer a pest free guarantee anytime for free so if we ever see anymore bugs we can call them and they will send someone out. I would recommend signing up with them.
