Good morning sorry I missed you today. I completed a one time service for wasps. I rang the doorbell with no answer. I inspected the front and rear of the building. I seen the nest in the dryer vent on the second floor. I knocked the nest out of the air vent and I treated the area with a liquid residual that will kill in control wash activity. Allow 7 to 10 days for the best results if you have any activity after this time, please call the office for service call. Thank you for choosing Green Pest solutions and have a wonderful day.
