Fly spray costs £9, 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. Making fly spray for your horse saves you money and allows you to control the chemicals within the spray. Many ingredients, like vinegar, have been used in homemade fly spray for generations. The spray doesn't hurt the horse and it creates a healthy, glossy coat.
