Good afternoon, today I completed your service call for hornets getting into the bathroom on the 2nd floor. While inspecting g, we did find that one hornet dying on the windowsill. I believe they are coming from the vent in the bathroom, as it aligns perfectly with the vent on the outside of the window and that’s where I saw the activity. I applied a liquid solution to that vent as well as around the window in case they are getting behind the window. Please give the treatment 5-7 days to see the best results. If you have any other general pest issue or concern, please feel free to contact our office. Thank you for choosing Green Pest Solutions and I hope you enjoy the rest of your day.
