Hello, today I was here for your one-time service for bald face hornet, first I applied a liquid treatment to the area to help eliminate majority of the nest. I removed parts of the nest and reapplied the liquid treatment to the area and then remove the nest and picked up majority of the debris as best as possible. Please allow 10 to 14 days for the material to take full effect. Thank you for choosing Green Pest Solutions and I hope you have a wonderful day.
