Farnam Endure Fly Spray for Horses — Long-Lasting, Sweat-Resistant Fly Control (Up to 14 Days, 128 oz Refill)

Overview

Hot days, humidity, and heavy sweating can challenge fly control. Farnam Endure Fly Spray is designed to help horses stay comfortable and protected during turnout, training, and performance. This water-based formula delivers broad-spectrum insect control without leaving a greasy residue, so your horse can shine rather than smudge with oil. Endure’s Repelock technology binds to the hair shaft to help maintain protection through sweat, humidity, and moisture—supporting dependable coverage when horses are active.

With up to 14 days of protection, Endure reduces the need for frequent reapplications compared with ordinary sprays. The flexible spray or wipe-on design makes it easy to cover the body, including sensitive areas like the face and legs, so you can tailor coverage to your horse’s needs while keeping comfort in mind.

What it protects against

• House flies, stable flies, face flies, and horn flies
• Gnats and mosquitoes
• Ticks, including deer ticks, and lice

Why riders choose Endure

• Sweat- and rain-ready performance in hot, humid environments
• Non-greasy finish that won’t coat the coat in oil
• Full-body coverage with spray or wipe-on application, including the face and legs
• Long-lasting protection—up to 14 days under typical use

How to use and complementary care

Apply Endure to clean, dry coat and allow to dry before turnout. Reapply as needed based on activity and conditions. For sensitive areas around wounds or sores, consider pairing Endure with SWAT Ointment. For integrated fly control, SimpliFly Feed-Thru and a reliable fly mask can help reduce fly exposure in the barnyard.

Endure is designed to support performance horses, pasture horses, and daily-use horses facing flying insects, gnats, mosquitoes, and biting insects. The result is a practical, flexible solution that fits a busy equine routine without heavy residue or stickiness.
