A Nairobi fly is a species of paederus crebinpunctatus and are said to cause blistering and irritation to human skins. How do they do it when they can’t bite or sting? How do you cure blisters from Nairobi fly?
The inner juices of these critters contain pederin, a rather potent organic toxin. If you squish those buggers in the areas that they live (East Africa) then you'll get that stuff on your skin and the blisters are the result.
