tiny biting bugs

Although I'm pretty sure that the true meds must do the best job against the results of these tiny buggers (pun intended) on one of my many trips into Mexico starting back years ago I was caught by them while out without protection or cure and was attacked by a swarm of them. I was in a lot of pain, and scratching like mad, when a local Mexican man told me to go to the nearest bathroom and put some soap on the problem area. It worked like a charm and I have used this method several more times since then with the same results. Just keep it in mind as a back up.
