We have used A-1 Exterminators for over five years and are happy with the results. When we do have a problem such as ants in summer A-1 is quick to remedy the problem. A-1 has a key to the house and often undertakes the treatment when we are not at home. We have never had any problem with A-1's work. The appliers are cordial and explain problems they see. Once again, we are happy with the relationship we have had with A-1 Exterminators over the years.
