Today I completed a one time be service. Mr. reported yellow jackets going in underneath the siding in a hole on the front of the home. I treated the area also the surrounding area with a liquid residual. This will kill and control the yellow jackets. Please allow 7 to 10 days for the best results. If you have any activity after this time, please call for a service call to treat again. Thank you for choosing Green Pest solutions and have a great day.
