After doing research on the Alpine pesticide that was used on the exterior of the house, I am impressed with the technology and even happier with the results. Two days after application, a few active odorous ants were observed on the inside. Many dead ants were seen at the carpet and outside wall interface. The transfer of bait concept rather than kill on site resolves the problem more efficiently and hopefully permanently. The cost to continue treatment on a quarterly basis is fair and will provide peace of mind. Fighting ants in the home is no fun. Thanks to Kelly Friedman and to Kevin at The Pest Doctors (A-Abel) the application technician for your service.
