I have been using Colonialpest for six months now and I am very pleased with their service. Whether it's mice problem, wasps or carpenter ants they are able to handle it. The staff is very professional and always on time. We have the semi annual program and it woks great. I had a concern once with the smell of the carpenter ants spray that was applied and the owner called at 9 pm the same evening i left a message which was very impressive.
