Good morning, it was nice meeting you today! I completed your service for ants today. Upon inspection, ants were trailing along the patio. I treated the exterior perimeter of the home, as well as around doors and windows, with a liquid residual for ants. I also treated around the perimeter of the patio, especially where activity was found. Please allow two to three weeks for full effect. If you have any questions or concerns, please give us a call. Thank you for choosing Green Pest Solutions!
