Aaron Dallas, a resident of Carbondale, has had five bot fly larvae removed from his head. Doctors initially diagnosed gnat bites, then shingles. When the spots started to move doctors knew that something unusual was wrong.

“I’d put my hand back there and feel them moving. I thought it was blood coursing through my head. I could hear them. I actually thought I was going crazy… It was weird and traumatic,” said Dallas.
