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.

Available in a Variety of Sizes

Both Repel-X Insecticide & Repellent and Repel-X pe Emulsifiable Fly Spray are available in a range of sizes to cater to different needs, whether for small-scale use on individual animals or larger operations that require bulk quantities.

Sweat-Resistant

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.

Doesn’t work

I’m so bummed. This has been my go-to fly spray in the past. But I’m so disappointed now. I doused my horses with this last night and when I put them out around

I’m so bummed. This has been my go-to fly spray in the past. But I’m so disappointed now. I doused my horses with this last night and when I put them out around 8pm they were immediately swarmed by horse flies. The spray was even still a bit damp on their backs and the horse flies were landing right on it. Going to see if I can return the bottles I got and I’ll never buy it again. They must have changed something in the last year since I bought it.

Only fly spray that works and hasn’t caused irritation

I have used Endure for many years, it is the only one that actually can last a few days and has never caused irritation or an allergic reaction. It worked wee in

I have used Endure for many years, it is the only one that actually can last a few days and has never caused irritation or an allergic reaction. It worked wee in the show ring as it didn’t cause oily patches, and now, I just like it for bug free pleasure rides. I can fly spray all the horses in the morning ahead of time, and they are fly free for the farrier. Wish it was a little cheaper, but glad it actually works.

Works well; container could be better.

I like this product because it sprays at all angles, and goes where you put it. The little spray button breaks VERY easily, though, so it only gets 4 stars.

Horse Flies

Horses usually do not like fly spray. Me on the other hand, I feel it works well, temporarily. Having to apply everyday during Horse Fly Season in Central East

Best Fly/Bug Spray on the market.

This spray is a bit more pricey than similar products, but it is well worth the money. It lasts for days and doesn't cause my sensitive large pony to break out in

The best fly spray out there!

I've been using this for years. I've tried all the others and even made my own and this definitely lasts the longest. My horses know the bottle and are very appreciative

Great product that does what it says, developed for wet environments. Thans chewy for the great price.

2nd best fly spray and has a less offensive smell

I prefer Ecovet, but that's almost too strong. Endure works very well. It won't make you or your horse choke. I find Endure has to be apply daily.

Chewy order

I often order heavy items and they are left at our front gate. I then have to struggle to get the boxes to the house. Can they either leave boxes on the front porch

I often order heavy items and they are left at our front gate. I then have to struggle to get the boxes to the house. Can they either leave boxes on the front porch or at garage door? Thanks!
