This will work--no exceptions! Run hot shower over body for a couple minutes to open pores; turn off shower; add 5 drops pure oregano oil to some liquid soap like Dr. Bronner's Eucalyptus Soap. Mix in hands and apply to one major limb--left arm, e.g. Do the same again for the right arm. Again for the torso, and again for both legs respectively. It will burn. Tolerate it for as long as you can--between 3 to 5 minutes at the most. Rinse.
For me it cures these no-see-ums that I presume to be some kind of mite. I frequently get infested after handling papers or books that have previously been infected. Why I just don't throw out all these things so that I'll never be exposed again, I don't know. Actually, it's because I'm an information junkie and hope that freezing or cooking in the oven will rid these papers/books of these parasites. Not necessarily! I just got a new infestation which brings me here to this website. I did "the treatment" just now and it works. It burns the little critters to death. Just accept that your skin will burn also for the 3-5 minutes before you rinse it, and somewhat after. But you will definitely feel an immediate sense of relief because your nerve endings won't be agitated any longer
