Pyranha Nulli-Fly Water-Based Spray for Sensitive Horses

Protect Sensitive Skin Without the Greasy Buildup

If your horse breaks out in hives or develops scurf from oil-based fly sprays, Pyranha Nulli-Fly offers a different approach. This water-based formula kills and repels flies, gnats, mosquitoes, and ticks without the harsh solvents that irritate thin-skinned horses. Because it's water-based, it dries clean — no oily residue to trap barn dust or dull your horse's coat before a show.

Built with Suspension Technology, the active ingredients stay evenly distributed in the bottle, so you get consistent protection from the first spray to the last without shaking. It's 33% stronger than leading economical brands, giving you professional-grade defense that's gentle enough for reactive horses and clean enough for the show ring.

Why Riders Choose Nulli-Fly

• No greasy residue or dust magnet — Water-based formula dries clean and actually repels dirt, keeping coats show-ready between baths.
• Formulated for sensitive skin — Won't cause the scurf, hives, or chemical burns common with oil-based sprays on thin-skinned horses.
• No-shake application — Suspension Technology keeps active ingredients mixed, so you can spray straight from the barn shelf without prep.
• Broad-spectrum kill and repellency — Targets stable flies, horn flies, deer flies, gnats, mosquitoes, ticks, and lice in one application.
• 33% stronger than budget brands — Professional-grade potency in a 32oz ready-to-use trigger bottle with a light citronella scent.

Frequently Asked Questions

Q: Will this leave an oily film on my horse before a show?

No. Because Pyranha Nulli-Fly is water-based, it dries quickly and leaves a clean finish that repels dust rather than attracting it. It's a go-to for Dressage and Hunter competitors who need fly protection without compromising coat shine.

Q: My horse gets hives from most fly sprays — is this safe for reactive skin?

Yes. Nulli-Fly is specifically formulated for horses with skin sensitivities. It delivers Pyranha's full-strength insect control without the harsh oil-based solvents that typically cause scurf or allergic reactions in thin-skinned breeds.

Q: Do I have to shake the bottle before every use?

No. The Suspension Technology keeps the active ingredients evenly distributed in the solution, so you can spray immediately without shaking. It's ready when you are, from first use to the last drop.
