Good afternoon. It was good talking with you. Today I completed your one time service for bees. I saw the area where the wasps were entering and exiting under the siding the upper left siding 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 still see 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.
