Good morning Jeremy. Today we completed your pest control service for Yellowjackets. We treated the exterior entry point with a liquid residual insecticide. Then we treated the interior breach point with a different liquid residual insecticide along with taping up the breach point hole. Please allow 5 to 7 days for this treatment method 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.
