Good morning. My name is Mark Ray. It was truly a pleasure meeting you today. I was at your home today to treat for the yellow jackets. I treated the entry point with a slow acting liquid residual products that should eradicate them over the next 48 hours as we discussed. We did see the ones in the basement around the window, trying to get out, but we were unable to ascertain how they were getting in. The slow acting residual liquid should eradicate them over the next two days. After that, you are still noticing any issues with them or if you have any questions or concerns, please do not hesitate to give us a call. Thank you for choosing Green Pest Solutions and have a great day.
