Have used them for many years. Very pleased with techs and office staff and the job they do. My bill went up by $5.00 initially and I did not have an issue. I just had my home sprayed, and the bill went up by $15.00. Apparently it was in fine print on my last bill. I would have preferred an email or phone call to advise me of same and the last increase was not gradual. I'm still going to use them.
