Hello doctor, I am very concerned about the "Nairobi Fly" (Paederus sabaeus) blisters, the blisters are caused by the Pederin contained in the acid-bug. I have no idea how to cure the painful blisters. Some say rubbing the area with a raw potato slice might help. Is this true? If it is, why is it? At night, I have over 200 of these bugs in my patio, it's terrible. Thank you.
