Good morning, it was a pleasure speaking with you over the phone and with your employees at the office. I completed your one time service call for yellow jackets. I inspected the interior and could not locate a specific area they were getting through but I did notice a hole on the exterior with some activity going in and out. I did treat that hole as well as a few yellow jackets entering the hole with a liquid solution. Please give this treatment 3-5 days to see the best results. Per the conversation I had with you as well as your employees, try to keep the air condition set to the coldest setting to help combat the yellow jackets on the interior. Within the hour I was here, it already made a huge difference. If you have this issue again, please do not use any foam to seal up the hole as that is just trapping them inside the property. If you have any other general pest issue or concern, please feel free to contact our office. Thank you for choosing Green Pest Solutions and I hope you e
