I thought bedbugs were bad, but now I discovered something worse: botflies. Their maggots actually eat living flesh and bury themselves underneath the skin of mammals, including humans. They start off as microscopic eggs but can grow up to an inch.

There common in Central and South America. I would suggest avoiding those places unless you wear a bunch of insect repellent.
