Watched his goofy show yesterday just because, but he showed a way to hang strips of meat to make jerky. After marinating the strips in a bag he hung them on the backporch (unprotected) and sprayed something on the meat that he said would keep ALL insects away from it. He said it was coming to the market sometime soon and that they had been using it for years. What is it? I would think some sort of vinegar based spray would really affect the taste of the meat. If this stuff works, I could see it working on everything from picnics and BBQs to a simple meal on the backporch.

Any clues?
