Good afternoon. Today I completed your one time service for yellow jackets. Upon arrival you showed me above the kitchen window yellow jacket nesting going in and out of the eaves. I applied a liquid treatment to the entry point. Please avoid the area for a few days. The yellow jackets are agitated and will sting. Within 3-5 days the nest should be under control. If you see anymore activity between 7-10 days please give our office a call to come do another treatment. Thank you for choosing green pest solutions. Have a great day!
