Good morning, it was nice meeting you today! I completed your initial pest control service today. I inspected the window where brown liquid was leaking out. I found no evidence of any bee activity. It is likely this is a moisture leak, possibly from the air conditioner above the window. I recommend having the window sealed and any moisture damage repaired. I applied a liquid non-repellent solution targeting ants throughout the interior of the bathroom. On the exterior, I swept away any cobwebs I saw. I then treated the exterior perimeters of the house and detached garage, as well as around doors and windows, with a liquid residual for ants, general and seasonal pest activity. Please allow two to three weeks for full effect. If you have any questions or concerns, please give us a call. We will return in about 30 days for your first quarterly service. Thank you for choosing Green Pest Solutions!
