Hello it was nice speaking with you today. I completed your quarterly service. I checked under the grooves of the home and under the propane tank lid for wasp activity, but found none. I applied an aerosol residual to these areas as you said wasps occupy them often. I also applied a liquid treatment to the perimeter foundation of the home. Please allow one to two weeks 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.
