Thank you for choosing Greenpest. My name is Eric and I was your technician for today. I began by inspecting the affected areas inside of your home. There was a large deep wall void in the closet of the area, where the wasps were active. I injected an aerosolized insecticide inside of your wall in the closet. Please allow for 2 to 3 days for the product to have full effectiveness. If you have any questions or concerns, feel free to reach out to us. Thank you and have a good day.
