I called Killo and they charged me $180 for a one time treatment where they treated the inside and outside. Although it reduced the number of ants, it pushed many of the outside ones into the house so the problem was not eliminated. I called Terminex at Indian Trail at a guy named Randy came out who has been with the company around 15 years. He knows his stuff and is very service oriented. I signed up for a full year service contract at $440 and that gives me quarterly treatments to take care of the bugs. Randy also gave me his cell number and told me to call him anytime if I still had any problems. I called him about some ant nest in the back porch and he's coming out to treat it at no extra charge.
I wouldn't give 5 stars lightly, but these guys did the job right and for a reasonable price. They also stand by their word which is more then a lot of other service companies do these days.
Make sure you get Randy to come out and talk with you about your problem as he really knows his stuff and works with you to eliminate the problem. BTW: no more ants in the kitchen, even by the dog food.
