Good morning, it was nice meeting you today! I completed your service for bees. I treated the paper wasp nest in the attic window with a liquid residual. Please allow five to seven days for full effect. Due to the location, I was unable to remove the nest, as I couldn’t open the window from the inside. I recommend sealing up the cracks around the window to prevent further nests from appearing. If you have any questions or concerns, please give us a call. Thank you for choosing Green Pest Solutions!
