Good afternoon, I completed your one time service call for yellow jackets. I taped off that hole they were getting through in your back room next to the garage. I treated the area on the exterior of your home that they were using to get into your home with a liquid solution. Please give this treatment 3-5 days to take full effect. If you do have any issues or concerns, please feel free to contact our office. Thank you for choosing Green Pest Solutions and I hope you enjoy the rest of your day.
