Hello, it was nice meeting you today. I serviced your home for yellow jackets. I applied a liquid treatment to the entry points to the nests where yellow jackets were entering. I also treated the part of the nest that penetrated into the garage. Please allow up to 7-10 days for the treatment to take effect. If activity continues after that time, please call for an appointment within your warranty period. Have a great day and thank you for choosing Green Pest Solutions.
