Today I completed your one time bee service. I dusted your home exterior for cobwebs. I treated cracks and crevices for yellow jackets behind shutters underneath the siding and any suspect places that yellow jackets could nest. The residual that we used is slow acting and long lasting. When itâ€™s dry the insect walks over it and gets infected by it and can infect other insects. It may take 3-5 days for the activity to cease. If you see activity after a week please call and get further treatment. The effected area that had activity was at the fence line into the backyard under the siding at the corner of the home on the driveway side. There is no visible nest. Thank you for choosing Green Pest solutions and have a great day.
