Good morning I completed your service today. I started by identifying the area where the yellow jackets are entering the siding. The area is above the front door next to the gutter. Before treating this area, I went inside to the attic and bedrooms to make sure there was no fear of them coming into the house. I then went outside and treated the area with a liquid residual for stinging insects. 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.
