Hot weather, humidity, and heavy sweat can challenge even the most reliable fly spray for horses. Farnam Endure Fly Spray provides long-lasting fly control designed for horses working and living in demanding environments. This sweat-resistant, rain-ready formula kills and repels house flies, stable flies, face flies, horn flies, gnats, mosquitoes, ticks, deer ticks, and lice, delivering dependable protection during turnout, training, and performance. Unlike many oil-based horse fly sprays, Endure's water-based formula won't leave a greasy or oily residue on the coat. Repelock conditioner technology binds to the hair shaft to help maintain even, consistent protection through sweat, humidity, and moisture. Farnam Endure provides up to 14 days of fly protection, helping reduce the need for frequent reapplication compared to ordinary fly sprays. The flexible spray or wipe-on application supports full-body coverage, including sensitive areas such as the face and legs. For complete fly control around the barn, pair Endure with Farnam SWAT Ointment for sensitive areas around wounds and sores, SimpliFly Feed-Thru Fly Control to stop flies before they hatch, and SuperMask Horse Fly Mask for reliable face protection. Endure is from the makers of trusted equine products like SandClear for horses and Red Cell Iron Supplement for horses.
