Hello, it was nice meeting you today. I completed your initial service. I inspected the exterior and swept away the spider webs I found outside. I treated the entry point to the yellow jacket nest as well. I applied a liquid treatment to the exterior perimeter along the foundation. Please allow up 7 days for the treatment to take effect. If the yellow jackets are active after that time please call for an appointment to have us treat it again. Have a great day and thank you for choosing Green Pest Solutions.
