Good morning. Today I completed your one time service for yellow jackets. I applied a liquid treatment to the yellow jacket nest at the corner of the porch by the front door and I also treated the nest in the rock bed on the front lawn. Please avoid the front door area for a few days. The yellow jackets are agitated and will sting. There were no other nests around the house at this time. Please allow 10 to 14 days for our products to take effect. Thank you for choosing green pest solutions. Have a great weekend!
