Good morning, I completed your quarterly pest control service today. Tenants reported no interior issues, but insects coming through the back door. I swept away any cobwebs I saw on the exterior. I then treated the exterior perimeter, around doors and windows, with a liquid residual for ants, spiders, general and seasonal pest activity. I thoroughly treated around the door of concern. 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!
