Hello Sharon It was very nice to meet you and as you know, my name is Kristen today. I came to treat your home for a one time service for Yellowjackets. After meeting up with you, you showed me the location and we talk and I caution you to stay away from the area for about 40 minutes after the treatment And then during the day that bees are gonna come and go excuse me the wasp is gonna come and go come and go picking up the product onto themselves taking it in and by seven or 8 PM tonight when they all return to the nest the nest will be 100% deceased. Tomorrow morning you can work in that area. If you have any questions or concerns, please feel free to contact us and thank you for choosing green test solutions as your pest control provider. Have a great day thank you
