Imperial pest prevention has been a straight up company to deal with. We hired them to get rid of some roaches from a used appliance set. Price was a little higher than the company certified but I felt that imperial was a little more professional and educational and had a gut feeling they were the ones to go with. Service has been nothing but spectacular. A few weeks in and we nothing around anymore. They came in with masks on and suits and went to town on the place. There was no playing around. Whatever they spray works better than any spray I have ever bought or any other company we have used has.
