I used Colonial for about 10 years from 2003-2013 but took a break from all pest control while I raised bees. I was completely satisfied with their service and had no insect issues over the years they treated our home. I began using them again this spring. The technician, Russ, was very informative and helpful, but it is too soon to comment on the results. I like that I received a summary of the chemicals used with my receipt.
