Hello! Today I completed your one time service for yellow jackets. Upon arrival you showed me a few dead yellow jackets inside, but mainly in master bedroom bathroom. Then you showed me the yellow jackets entering through back left corner of siding. I applied a liquid residual under siding to back left corner of home for yellow jackets. Please allow 7-10 days for treatment’s best effects. If yellow jackets persist after 7-10 days, please give us a call back for another treatment. Thank you for choosing Green Pest Solutions!
