I need some help or suggestions PLEASE. I have a small area (about 5 or 6 inches round) in the corner of my kitchen ceiling. I thought it was a roofing issue,but it's not. Had the roofer come out and he said that it's a yellow jacket nest in between the roof and rafters that's creating the damage. Does anyone know an exterminator to spray and then cut out the small section of ceiling and replace and patch with drywall? If you do, please let me know.
