About Farnam Endure Sweat-Resistant Horse Fly Spray

Powers Through Sweat

Keep bugs off from head to hoof. Endure provides up to 14 days of sweat-proof fly control. It helps protect your horse from diseases transmitted by flies, gnats, mosquitoes, and ticks. Choose from 15 oz. finishing spray, 32 oz. ready-to-use spray, easy-pour 128 oz. gallon refill, and the handy 3 oz. Endure roll-on for your horse’s eyes and ears.

Complete Protection

Ideal for protecting hardworking horses from insect pests in the most challenging conditions, Endure spray features special RepeLock conditioner to reduce biting and discomfort. It comes in an easy, ready-to-use spray bottle for even application and can even be applied in the rain and when your horse is sweating.

Create a No-Fly Zone

Farnam’s No Fly Zone horse products provide comprehensive pest protection. The three-step approach includes the SuperMask II horse fly mask to BLOCK insects from your horse’s face, Endure Sweat-proof Spray to REPEL pests, and SimpliFly Feed-Thru Fly Control to REDUCE flies. Together, they help keep insects away from your horse’s face and body, act as a safeguard against six types of flies, gnats, mosquitoes, lice, and deer ticks, and prevent the development of house and stable flies. 


The unique RepeLock conditioner in Endure spray helps ensure a fly-free zone, reducing biting and discomfort for your horse. The hardworking, sweat-resistant formula keeps on protecting, too—even in hot, muggy, sweaty conditions!

Easy Application

Applying Endure is easy—simply brush your horse’s coat, shake the product well, and spray. For application on the face, apply using a clean wipe and gloves, avoiding the horse’s eyes, nose, and mouth. If the horse is dirty, shampoo and rinse thoroughly first, making sure the horse is dry before application. Reapply every 5-7 days initially and then every 10-14 days for optimal coverage. You’ll also need to reapply if the horse is washed or exposed to heavy rain.
