I have used Truly Nolan for 30 years, including the two times we have lived in Tucson. Overall, I have been reasonably satisfied. I think they are higher priced than many of their competitors. A few years ago, I had one of your service people service me for several years. During that time, I captured over 30 live centipedes in my hours. I inquired several times of my (your) service person, and he told me there was nothing they could do to prevent that.
