Farnam Endure Sweat-Resistant Fly Spray For Horses - 1 Gallon Refill, Kills & Repels Flies, Mosquitoes, Ticks

Summer flies driving your horse crazy? Farnam's Endure spray is a heavy-duty option that really works, even on sweaty, hard-working horses. Its big claim is the \Repelock\ conditioner in the formula – it's supposed to bind to the hair shaft, so the protection lasts through sweat and even light rain. It repels and kills biting flies, mosquitoes, gnats, and ticks (helping reduce the risk of stuff like Lyme disease). A single application can protect for up to 14 days, which is awesome. This specific listing is for the huge 128-ounce (1 gallon) refill jug. It's the most economical way to buy it if you have multiple horses or use it all season long. You'll just pour it into your smaller spray bottle. It's a vet-recommended brand and a favorite among many horse owners for tough bug conditions.
