Ya might want to put a band-aid on that...
I saw something like this on TV not too long ago. They are using laboratory grown maggots to clean out rotten flesh on wounds and such. They showed a man with big rotten spot on his leg, and they slapped a bunch of clean maggots (if there can be such a thing) into the wound and then bandaged it all up where they couldn't crawl out. They opened it up a day or two later and cleaned off the now fat maggots and where the rotten flesh was, was now fresh red meat, ready to sanitize, bandage and let heal. UNNNGH!
