The Beef-worms, or bot-flies in the bush are pretty freaky. The bot flies' eggs, and then the larvas stay under your skin until ready to "pop-out". In between they make their own breath holes via your skin. Later they pop out of the hosts skin and drop to the ground digging into the soil. Later they make it to being an adult fly. The Belizean agric. minis. has fought against this nasty flies for years, and it appears there are not so many problems. Spray yourself for deet products always. Of course Tommy-Goffs don't care about sprays.............mel s.
