Good afternoon I completed your service today. I started by inspecting the interior of the home. I could not find any entryway that the yellow jackets were using. All of the yellow jackets inside are currently dead. I went outside and identified the vent that they are flying into. I treated this area with a liquid residual for stinging insects. Please note that it may take a day or two for the activity to subside. 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.
