Good afternoon and thank you for choosing Greenpest solutions for your pest control needs. My name is Eric and I was your service tech for today. I begin by inspecting the infected area for wasp activity after I was able to determine the entry and exit point. I applied a liquid residual insecticide to the infected area. Please allow for 3 to 4 days for our product to helpful effectiveness. If you have any questions or concerns, feel free to reach out to us. Thank you and have a great day!
