Good afternoon I completed your service today. I identified where the yellow jackets were entering and I treated the area heavily with a liquid residual for singing insects. I also removed the paper wasp nest in the garage. Please allow at least a week or two for the treatments full effect. As a reminder, you do have a 30 day guarantee, and do not be afraid to call us back if needed. If you have any other questions or concerns, please reach out to the office. Thank you for choosing Green pest solutions.
