One Application. Up to 17 Days of Protection.
Your horse is stomping, swishing, and breaking focus before you've gathered your reins. UltraShield® EX is the most advanced fly spray formula Absorbine® offers — sweat and weatherproof, with up to 17 days of protection against flies, mosquitos, and ticks.
The Problem
You Spray Before Every Ride and the Flies Come Back Before You Reach the Gate
It starts the same way every summer morning. You pull your horse from the paddock, cross-tie him in the aisle, and reach for the fly spray. He stands still for the ritual, because he knows it's coming and because somewhere in his memory he trusts it. You coat his legs, his belly, his face, the underside of his jaw. You step back. He looks calm. You tack up, walk to the mounting block, and before you've gathered your reins he's already stomping at his left front.
By the time you're ten minutes into your warm-up, the flies are back. Not one or two, but a cloud of them hovering at his flanks, landing on his ears, clustering at the corners of his eyes. He breaks from the trot, tosses his head, swishes his tail so hard you feel the tension travel up through the saddle. You're not schooling anymore. You're just trying to keep his attention.
Trail riders know this one best. You packed extra spray in the saddlebag. You stop mid-trail, reapply, and watch the bottle drain faster than you planned. Your horse is patient by nature, but by August he's flinching at shadows and reacting to every brush of air on his skin, because the flies have taught him to expect it.
Fly season doesn't just cost your horse comfort. It costs you the ride. Schooling sessions turn into endurance contests. Trail rides you looked forward to become management exercises. Barn time you used to enjoy turns into an arms race with insects.

Why It Keeps Happening
Sweat Is What Resets the Clock
The problem isn't your technique, and it isn't your horse. It's where the protection goes.
A horse in work sweats from the neck, the flanks, and the chest, which is exactly where flies concentrate. When protection is sitting on top of the coat, sweat carries it off, and the clock you thought you had starts over somewhere in the middle of your first canter set. That's why a heavier application doesn't fix it. Neither does reapplying after every ride, layering wipes over the top, or switching brands every June. You end up with a horse who smells strongly of everything you've tried and still stands nose to the fence in the corner of the pasture, hunting a breeze.
Rolling doesn't help either, and in July your horse rolls roughly every time you turn your back.
So you decide fly season is something to be endured rather than solved. Reapply, rewrap, resign yourself. What actually needs to change isn't how often you spray. It's whether the protection stays put through sweat and weather in the first place.

The Solution
Up to 17 Days. Sweat and Weatherproof.
UltraShield® EX is the most advanced fly spray formula Absorbine® offers — a proven insecticide and repellent for horse and dog owners who depend on long-lasting protection and comfort. The sweat and weatherproof formula provides up to 17 days of protection against flies, mosquitos, and ticks, held to the coat by UltraBond® Technology rather than sitting on the surface where sweat and rain can take it away.
The active ingredients are Natural Pyrethrin, derived from chrysanthemums, along with Permethrin and Piperonyl Butoxide. Together they kill and repel more than 70 species of flies, mosquitoes, ticks, and gnats.
The base formula does more than carry the actives. It's ready to use and water-based, with multiple sunscreens and coat conditioners including aloe and lanolin, so every application is also doing something for the coat it lands on. UltraShield® EX is labeled for use on horses, ponies, foals, and dogs over 12 weeks of age, as well as on stalls and bedding. Always follow the product label.
We keep UltraShield® EX on the shelf because riders come back for it. Apply once before a multi-day trail weekend and come home to a horse who stayed comfortable. Take the 128oz gallon for a barn full of horses through a season, or the 32oz spray for the saddlebag. Made in Australia.
