Today I completed your one time pest service for Yellowjackets. The Yellowjacket nest between wood pile and detached garage was treated with a liquid residual application. Please stay away from that area for any remaining Yellowjackets will be agitated, and allow 3-7 days to see a decrease in activity. And after 10-14 days if you see activity in the woodpile area please contact our office. Thank you for choosing Green Pest Solutions and have a great day.
