Good afternoon it was a pleasure speaking with you today. I completed a one time bee service for bees in the ground. I inspected the area and saw the yellow jackets in a hole in the ground. I treated the area with a liquid residual. I put a gallon of the liquid in the hole. Allow 3 days to see the best results. If there is any activity after this time please call the office for a free service call. If you find any other nests in the warranty period you can also call for them as well. Thank you for choosing Green Pest solutions and have a great day.
