Set It and Forget It — 24/7 Fly Protection for Your Barn

The Country Vet Automatic Metered Dispenser delivers consistent fly and odor control without the daily ritual of hand-spraying stalls. This professional-grade barn fly control system releases a metered dose every 15 minutes, creating a continuous barrier against biting flies, mosquitoes, and gnats — even when you're not on-site. Built for horse owners who want reliable protection without constant maintenance, this unit runs for 30 days on a single 6.4 oz refill and up to two years on a set of D-cell batteries.

The sandy beige housing isn't just for looks — it's designed to blend into barn walls and hide the inevitable layer of dust and hay dander that settles on everything in a working stable. Whether you're protecting a four-stall block, a tack room, or a feed room, this dispenser covers up to 6,000 cubic feet and is EPA registered and USDA authorized for use around horses and feed storage areas.

Frequently Asked Questions

Q: How many units do I need for a standard barn aisle?

For optimal coverage, space units every 20 to 30 feet along the aisle. Each dispenser covers 6,000 cubic feet, so measure your barn's square footage and ceiling height to calculate how many you'll need to maintain a consistent barrier against flies entering through stall doors and bay openings.

Q: Is this safe to use around my horses and in my feed room?

Yes. Country Vet dispensers are EPA registered and USDA authorized for use in stalls, feed rooms, and wash bays. Mount the unit at least 7 feet high and ensure it's not spraying directly onto hay, grain, or water buckets. The metered spray is designed to create an airborne barrier, not coat surfaces.

Q: How long does one refill canister last?

A single 6.4 oz Country Vet refill lasts 30 days when the dispenser is set to the standard 15-minute interval. You'll get a full month of protection per canister, making it easy to plan refill orders and minimize ladder trips during busy seasons.
