Natural Fly Spray 1 quart Raw Apple Cider Vinegar, 1 teaspoon Citronella Essential Oil (I found this at my local natural foods store, Mix together in a spray bottle. Apply to the animals frequently (give it a good shake before applying).
Using human socks to help protect horses legs from bites, etc. Can also be sprayed with fly spray or diluted essential oils, omg this cracked me up but great idea.Also, keep those white socks clean before a show!
