Good afternoon, I was here today to complete a one time service for carpenter bees. I inspected the exterior of your home for carpenter bee activity and holes. I located for carpenter B holes two on a long roof line and two in the fence. I applied a liquid non-repellent solution to the carpenter B holes. Please allow 10 to 14 days for best results.If carpenter be activity persist, please call our office for retreat. Have a wonderful day. Thank you for choosing Green Pest Solutions.
