Good morning, I was here today to complete a one time service for bees. I inspected the area and observed yellow jackets going underneath siding at the roof line to the right of the chimney. I applied a liquid non-repellent solution to the entrance exit points to combat yellow jackets. Please allow 3 to 5 days for best results. If yellowjacket activity continues after five days, please call our office for additional treatment. Have a great day. Thank you for choosing Green Pest Solutions.
