Steve from Alternative came and inspected the cause of ant's climbing on outside of my home, fully explained that they were carpenter ants and mostly likely were not in home as I had not seen any in house, he located what he believe was the nest they were coming from, gave me what I felt was a fair price for their service and treated the inside and outside including the suspected nest, Two days later no ants were on house and after a week still no ants. I would diffidently recommend him, I also like to use local services instead of the corporate giants.
