Hello it was nice speaking with you today. I completed your service call for wasps. I applied a liquid residual to the ground nest in the back yard as well as a crevice above the porch where I noticed wasp activity and mud tubes along the house. Please allow one to two weeks for treatment to take effect. I recommend filling the hole once activity wears down so it’s not reused. If you have any other pest issues, feel free to give us a call. Have a great day and thanks for choosing Green Pest Solutions.
