Good afternoon, it was nice meeting you today! I completed your service for bees. I used an aerosol to treat the yellow jacket nest above the basement insulation. I also used it to knock down any bees still flying around. I pushed the insulation back up to prevent bees from coming back down into the living space. On the exterior, I treated the entry hole with a liquid residual. Please allow five to seven days for full effect. If you have any questions, concerns, or if you continue to see activity, please give us a call. Thank you for choosing Green Pest Solutions!
