Technician Donny Moss was prompt, respectful, and finished the treatment quickly. It was a very hot day and he never complained about the heat as he treated the exterior of the house or the attic. A couple of days after the indoor treatment there have been several ant sitings, but I was told to expect that as the pests sense the poison and shift positions. I can't give five stars without seeing if the treatment was completely effective, but I'm hopeful all of the ants will be gone soon!
