Good morning. It was good talking with you. Today I completed your one time service for bees. I inspected the area of concern on the exterior and noticed wasps coming in and out of the void in the gas line. I spot treated this void and the surrounding areas with a non repellent treatment targeting wasps. This is a slow acting treatment and will not kill all of them immediately. Please allow 5-7 days for optimal results of this 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.
