Use a Bag of Water With Pennies Inside to Deter Flies

To make this ingenious fly deterrent, fill a heavy-duty freezer bag with water, table salt, lime juice, and add a few pennies. Hang the bag above a door or anywhere you have a fly problem. Make sure the bag is hanging in a place where it can reflect light. When the water and the coins reflect back into the flies eyes, it causes an unpleasant sight and causes them to have a hard time focusing on where they are flying. The flies eventually learn to avoid the area.
