Good morning Ryan. Today we completed your pest control service for yellow jackets. We could not find an internal breach anywhere at the time of inspection. We did treat the exterior entry point on the front of the home with a liquid residual insecticide. Please allow this treatment 7 to 10 days to reach its maximum effectiveness. If activity persists after that timeframe, please don’t hesitate to contact our office. thank you for choosing Green Pest solutions and have a wonderful day.
