Good morning, Kim. Today we completed your pest control service for Yellowjackets. We treated the entry points of multiple areas where yellow jackets were entering in the siding/eaves and around the awning with a liquid residual insecticide. Please allow 7 to 10 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.
