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 under the left upper corner above the window on the front right hand side of the house. 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. I also spot treated a few yellow jackets in the upstairs bedroom with an aerosol treatment. It is recommended to close all of the screen doors to prevent the yellow jackets from entering the home. If you have any further questions or concerns please contact our office. Thank you for choosing Green Pest Solutions and have a great day.
