How to Make Homemade Fly Spray for Your Horse

Fly spray costs $15 dollars, at the time of publication, for a couple days of fly protection, but you can make fly spray with ingredients found in health food, grocery and tack stores.

The spray doesn't hurt the horse and it creates a healthy, glossy coat.
