Good morning. Today I was here to complete a one time service concerning bald faced hornets. Nest located in tree near road. I applied a liquid residual solution directly into openings making contact with hornets as they enter an exit. After treatment, I removed nest from tree. You may see some lingering activity in area where nest was located, but they will soon disperse. For any other concerns, feel free to contact the office. Have a good day and thank you for choosing Green Pest Solutions.
