Good morning I completed your service today. I started by identifying the breach hole in the living room. I then went outside and took some time to identify where they are entering the house from. They are entering from an eave by the second story window. I blocked off the breach entrance with blue painters tape. I then poked a hole and treated the breach with an aerosol designed for stinging insects. After that, I went outside and treated the entrance area with a liquid residual for stinging insects. Please leave the tape over the hole until we are sure the problem is gone. Please allow at least a week for the treatment full effect. If you have any questions or concerns, please reach out to the office. Thank you for choosing Green pest solutions.
