Good afternoon. It was good talking with you. Today I completed your one time service for bees. I saw the area where the yellow jackets were entering and exiting the opening next to the front door on the upper right hand side. I applied a slow acting non repellent treatment to and around this area. Activity between 2-5 days is normal. If you are still seeing activity after 5 days, give us a call and we will return for another treatment. If you have any further questions or concerns please contact our office. Thank you for choosing Green Pest Solutions and have a great day.
