Prozap Fly-Die Equine Fly Spray - 32 oz Horse Fly Repellent for Stables, Barns & Outdoor Riding Protection

I bought this as an alternative to ultrashield EX. It’s cheaper at other retailers, but I needed it asap as I ran out (oops) of the EX that I’ve sworn by for years. This smells awful, but it WORKS and the chemical-y smell goes away quickly. We currently have a corn fly infestation where I board (thanks to a shared property line) and my gelding is NOT tolerating it well. He can be sensitive to some fly spray, so I sprayed one spray on each knee/hock and one on his withers. The bugs wouldn’t get within a foot of landing on him before making a swift u-turn. I also sprayed my shoes with it and they left me alone, too. Will absolutely continue using this.
