Good morning I completed your service today. I started by inspecting around the attic and noticed that the singing insect in question is a mud Dauber. These are typically outdoor insects and probably snuck in through a window or crack in the attic. I inspected around both crawlspace and attic to make sure there are no nests around. I then walked the exterior checking for nests on the house. I found no nests on the house, however, I did find a few cicada killer holes in the front mulch area. I treated these holes with a liquid residual for stinging insects. Please allow a week or two for the treatments full effect. If you have any questions or concerns, please reach out to the office. Thank you for choosing Green pest solutions.
