Rescue! Big Bag Fly Trap — 40,000 Fly Capacity for Barns

Stop Flies Before They Reach Your Horses

The Rescue! Big Bag Fly Trap creates a perimeter defense around your barn, intercepting House, Stable, and Face flies before they can swarm your horses' eyes and legs. Position this high-capacity trap 20 feet from your stalls, and it pulls thousands of pests away from your livestock — reducing the risk of conjunctivitis, summer sores, and the constant tail-switching misery that comes with heavy fly pressure.

Designed for active barns and manure-heavy environments, this disposable trap uses a potent food-grade lure that mimics the scents flies instinctively seek. Once you add water to activate the bait, it starts working immediately — no chemicals, no reusable containers to scrub out, and no touching a bag full of dead flies when you're done.

Why Barn Owners Choose the Big Bag Fly Trap

• Massive 40,000 fly capacity — engineered for high-pressure agricultural environments where standard traps fill up in days.
• Targets the flies that matter — specifically lures House, Stable, and Face flies away from your horses' sensitive eyes, muzzles, and legs.
• No-touch disposal — 18"L x 12"W x 8"H disposable plastic bag means you never handle the catch; just toss the entire trap when full.
• Water-activated bait — fill to the line, hang it up, and the food-grade lure begins drawing flies within minutes.
• Perimeter strategy — hang it 20 feet from the barn to intercept pests before they ever reach your horses, not after they're already swarming.
• Non-toxic formula — safe for use around livestock perimeters without harsh poisons or sprays.

Best For

Barn managers and horse owners dealing with heavy fly populations in manure-heavy or high-humidity environments.

Frequently Asked Questions

Q: Where should I hang this trap to protect my horses?

Hang the Rescue! Big Bag Fly Trap at least 20 feet away from your barn, stalls, or paddocks. The lure is intentionally strong — if you place it directly in the stall, it will draw flies toward your horses instead of away. Perimeter placement intercepts pests before they ever reach your livestock.

Q: Will this help with the flies that cause eye infections and summer sores?

Yes. This trap specifically targets House and Face flies — the filth flies that congregate around manure and moisture and cause eye drainage, conjunctivitis, and skin irritations. By reducing these populations around your barn, you significantly lower the risk of fly-borne infections.

Q: How long does one trap last before I need to replace it?

In heavy-pressure environments (active barns with multiple horses), the Big Bag typically fills in 2–4 weeks during peak fly season. Once it reaches capacity or the bait weakens, simply dispose of the entire trap and hang a fresh one.
