Good afternoon. My name is Mark Ray. I was at your home today to treat for the yellow jackets. They were going in and out of the void in the wall. I treated the entry point with a slow acting residual liquid product that should kill the whole hive within 48 hours. It after 48 hours you are still seeing any activity, please do not hesitate to give us a call. I also inspected all around the perimeter of your home for any other activity and I did not find any other activity. Thank you for choosing Green Pest Solutions and have a great day.
