Good morning Alan. Today we completed your pest control service for Yellowjackets. We treated the entry point behind the rear light fixture with liquid residual insecticides. We recommend avoiding this area until live activity ceases, which can take 5 to 7 days. If live activity persists after this timeframe, or you have any questions/concerns, please don’t hesitate to contact our office. Thank you for choosing Green Pest solutions and have a wonderful day.
