A friend who lives in the country is trying to keep flies out of her cafe. She heard a rumor about an Amish technique where you can keep a clear bag of water over the entrance, and somehow the light refraction keeps them away. Sounds like an urban myth, but short of swatting or unsightly strips, does anyone have any ideas about how to conquer flies?
