Absorbine UltraShield Gold Fly Spray – Blocks 100+ Insects

Stop Bugs Before They Ever Find Your Horse

Absorbine UltraShield Gold uses breakthrough FlyShield technology to disrupt an insect's homing system — so flies, mosquitoes, ticks, and 100+ other biting pests can't locate or land on your horse. Instead of just repelling bugs after they've homed in, this water-based spray creates an invisible shield that keeps them from even knowing your horse is there. No greasy residue, no daily reapplication — just long-lasting protection that stays active for up to 17 days, even through rain and sweat.

Backed by a decade of field testing and made in the USA by W.F. Young (the Absorbine family since 1892), UltraShield Gold delivers EPA-approved kill and repel performance with a bright citrus-leather aroma horses actually tolerate. Safe for horses, ponies, and foals — plus approved for premise use around barns, doorways, and stalls. Comes ready to use, so you can protect your horse the moment you open the bottle.

Why Riders Choose UltraShield Gold

• Disrupts insect homing before they bite — FlyShield technology stops 100+ species (flies, mosquitoes, ticks, gnats) from locating your horse in the first place, not just repelling on contact.

• Water-based, no greasy mess — Ready to use straight from the bottle with no mixing, and won't leave oily buildup on coats, blankets, or grooming tools.

Frequently Asked Questions

Q: How is UltraShield Gold different from regular fly sprays?

UltraShield Gold uses FlyShield technology to disrupt an insect's ability to locate your horse, stopping bugs before they even land — not just repelling them on contact. It's also water-based and can last up to 17 days depending on conditions, so you're not reapplying every day like most traditional sprays.

Q: Can I use this on my dog or other animals?

UltraShield Gold is approved for horses, ponies, and foals only when it comes to direct animal application. However, it is approved for premise use, so you can safely spray barn doorways, stalls, and turnout areas. If you need a dog-safe formula, Absorbine UltraShield EX or UltraShield Green are approved for use on dogs and puppies.

Q: Does it really last 17 days, or do I need to spray more often?

The 17-day range is the maximum under ideal conditions — light work, minimal sweating, and no bathing. Most riders reapply every 3–7 days during heavy turnout or after baths, and every 1–2 days during peak fly season or high-sweat work. You'll know when to reapply based on bug pressure — if flies start landing again, it's time for another coat.

Q: Will this work in humid or rainy climates?

Yes. UltraShield Gold is formulated to stay active through rain, sweat, and humidity — it's designed for all-weather performance. The water-based formula bonds to the hair shaft without washing off easily, so you get reliable protection even during wet turnout or summer storms.
