Good morning I completed your service call today. I identified where the yellow jackets were entering. There looks to be a little hole in the siding of the house right next to the front door. I was able to treat the area with a liquid residual for stinging insects. Please allow at least a week or two for the treatment full effect. I would advise avoiding this area for at least a day or two. If you have any questions or concerns, please reach out to the office. Thank you for choosing Green pest solutions.
