Hello, today I serviced your home for yellow jackets. I inspected the interior for potential breech points and did not find any. I applied a liquid treatment to the entry point to the nest. I also treated the exterior perimeter along the foundation. I swept away some old paper wasp nests as well. Please allow about 7 days for the treatment to take effect. If activity continues after that time please call for an appointment. Have a great day and thank you for choosing Green Pest Solutions.
