Country Vet Fly Spray Refill – 30-Day Automatic Metered System

Transform Your Barn Into a Fly-Free Zone — Automatically

Barn flies don't just annoy — they stress horses, spread disease, and disrupt your daily routine. Country Vet Fly Spray Automatic Metered Refill gives you 30 days of hands-free protection with natural pyrethrin technology that delivers a precise knockdown every 15 minutes. No manual spraying, no chemical buildup, just consistent coverage for up to 6,000 cubic feet.

The 0.975% pyrethrin formula is derived from chrysanthemum flowers and EPA-registered for safe use in stalls, tack rooms, feed rooms, and grooming areas. Unlike topical sprays that wear off, this system works around the clock — so your horses stay comfortable and you stay ahead of the flies.

Frequently Asked Questions

Q: How long does one refill canister last?

When used with a Country Vet Automatic Metered Dispenser set to 15-minute intervals, one 6.4oz canister provides 30 days of continuous protection. That's one full month of hands-free fly management per refill.

Q: Can I spray this directly on my horse before riding?

No, this is a premise spray designed to treat the air in enclosed spaces like stalls and tack rooms — not for topical use on animals. For on-horse fly protection, you'll want a separate equine fly repellent formulated for direct coat application.

Q: Is it safe to use in my feed room or near hay storage?

Yes. Country Vet Fly Spray is USDA-rated and EPA-registered for use in agricultural settings, including food-handling areas. Just follow label directions and ensure proper ventilation in enclosed spaces.

Q: What size area does one canister cover?

Each refill covers up to 6,000 cubic feet — that's roughly a 30' x 20' space with a 10' ceiling, perfect for a single stall, small tack room, or grooming bay.
