The EQyss Grooming Products Barn Barrier Natural Fly Repellent for Horses is a citronella-free fly repellent that’s an all-natural and safe option for use on your horse， pony or foal. A blend of four botanical oils tells horn flies， face flies， stable flies and house flies to buzz off and leave your horse alone. This formula is pH balanced， so it won’t irritate your sensitive horse’s skin or cause damage to his coat， mane or tail. Its clean， fresh scent is a great change from traditional chemical-smelling repellents， and it’s also safe for use on bedding， bridles， blankets and tack.
