Hello it was nice speaking with you today. I completed your service call for yellow jackets. I used a liquid residual to treat the ground nest and the opening they were flying into the siding of the home. I inspected around the rest of the home and garage and found no other nests or activity. Please allow 5 to 7 days for treatment to take effect. If you have any pest issues, feel free to give us a call. Have a great day and thanks for choosing Green Pest Solutions.
