Very thorough. 2 servicemen came out. I had a carpenter bee issue in the garage. Wasps around porches and window shutters. Spiders throughout the yard. They even sprayed inside the home, the yard, the outside structures. Very professional, reasonable price. I did the one time treatment, because I’m selling the house. But I would highly recommend the yearly contract for their services. You could see the difference within 20 mins. I was very impressed!
