. Well here you go. This is a rough outline. Hopefully it will at least provide a starting point...
Adult are fairly sizeable worm/maggot type creatures (This is just a guess from external observation. I haven't been able to exract one without pulverizing it first). they dont burrow particularly well but can travel through the weak flesh left behind by the newborns... adults see to inhabit the rim of a nest (sore). They are generally recognizeable by being a cresent shape bulge along the rim of the sore. One end is generally larger than the other. it is from this position that they lay eggs/cocoons throughout thde base of the sore, parhaps a couple milimeters apart. they might be mistaken for the remains of hair folicles or the like - dont be fooled.
Within these egg/cocoons, the newborns reach "newborn maturity?" i dont yet know the time period necessary (in fact, i dont know the time period for any of these events yet). The eggs while visible poking out of the center portion of the sore, hatch inward.
The emerging newborns look like thin hairs or fibers, black in color (maybe the red and blue ones come at a more advanced stage of the condition - i had them at various times- only once in a 'massive' sort of way). The newborns are the eaters. The burrow their way out of the area occupied by the sore and seek out a new site. There are many of them and they search diligently, attemting to establlish a site based on unknown criteria. Upon establishing a site, the newborns "merge". This is the stage where one finds the "hairy balls". lol The fibers/hairs whatever, merge and eventually solidify into what i call a "node". These are virtually indestructible little balls. I suspect that given enough time in a site, they develop into an adult, at which point the papule if previously undesturbed will become a sore. The adult will set up shop and begin laying eggs.
Now, the interesting part is that unless a site is completely healed, it can be reused. A disturbed node can arrive at it and set up shop. ...a disturbed node: if a node is disturbed prior to maturation it will evacuate a site, travelling throughout the weak flesh (i has kind of a watermelon like consistency) until they find an abandoned site or break in the skin, where will try again.
This is only a description of part of the disease's scope. there are many other characteristics and subtleties which i am too tired to pull together right now. i just wanted to get this information out there... Do Not Use Flea Killer as a topical - IT WILL KILL YOU. I will be honest and say I've been having progress with some other less lethal insecticides - ALL INSECTICIDES WILL HARM YOU, IF NOT KILL YOU.
IVE HAD EQUIVALENT SUCCESS USING LOTRIMIN AF. Actually, I use the generic Cloritrimazole cream. The best results i've had have been with the cream as a topical combined with Griseofulvin and Ivermectol (There was a third I found effective, but i cant remember it off hand).
I think you'll find that the reason this is so hard to kill is because of how resiliant the nodes are, and having to kill all five stages at once: adult, cocoon, fiber, fuzz ball, and node. Without killing ALL OF THEM, the condition starts right back up. And with many sites in any one area of your body, and then in multiple different areas of the body, you can see how this is a formidable task without knowing an exact procedure, etc.
