Today I completed your one time service for Yellowjackets. It was nice to meet you today. You indeed had a Yellowjacket nest in the ground in front yard. I treated the entry point of ground nest with a liquid residual application. Please stay away from this area for the remainder of the day for the returning Yellowjackets will be agitated. You should see a decrease in activity in the next 3-7 days and after that you shouldn’t see any more activity. Please contact our office if you have any questions or concerns. Thank you for choosing Green Pest Solutions and have a great day.
