Hi. I am reading this years after you posted it but I want to reply.... when I was stricken with morgellons, I noticed those gnats everywhere! It got so bad that I washed every article of my clothing in hot water and dried on high heat. I was finding gnats dead, stuck to my clothing. It was gross. I still couldn’t kill them all. I have never talked to a doctor about this because I see the ridicule others go through. It’s so sad. My symptoms have improved since 2012 (when it started) but I still wonder what it was that changed my life Forever. I still feel unwell 8 years later. Hopefully one day there will be a cure and people like me can come forward and get treatment. Thanks for your post and all your research. Just wanted to say you’re spot on with the flies.
