Here’s a crazy cool tip shared with us from our friend Cindi to help keep flies away. Take a few Ziploc® bags and fill them half full with water, add three to six pennies, and zip them shut. Pin one above the door to your trailer, barn door, kitchen window – wherever flies congregate. Apparently this creates a prism effect and movement that the flies perceive as a potential predator since flies are prey for other types of insects, birds, etc. Give it a try and let us know if it works!
