Catchmaster Disposable Outdoor Fly Trap — 8 Hanging Bags, Extra-Large 30,000-Fly Capacity, Pre-Baited

Catchmaster Disposable Outdoor Fly Trap is an easy-to-use, baited hanging bag that lures and contains large numbers of flies so you can keep patios, barns, and trash areas fly-free without sprays.

These pre-baited, single-use fly bags are built for heavy fly pressure and simple setup: unscrew the lid, add water to the fill line, hang the bag where flies congregate and out of the way of people, and let the food-based lure draw flies in. Each bag is sized to capture up to 30,000 flies and is disposed of intact—no messy transfer or contact with trapped insects.

How does this trap pull flies away from where people gather?

The trap uses a proven food-based attractant that emits an odor flies seek. Hang the bag downwind and away from seating or doorways so the scent draws flies toward the trap instead of toward people or pets.

• Food-based lure formulated for house flies and blowflies
• Best hung 20–30 feet from gathering areas downwind
• Works in sunlight where flies are active

Will one bag handle heavy fly pressure on a farm or dumpster?

Yes. Each extra-large Catchmaster bag is rated to hold up to 30,000 flies before needing disposal, making it suitable for barns, stables, garbage enclosures, and other high-traffic fly spots. Use multiple bags to create a perimeter or protect large areas.

• Extra-large capacity prevents quick fill-up
• Eight bags per pack for wider coverage or rotation
• Effective for agricultural and residential settings

How simple is setup, use, and disposal?

Setup takes a minute—unscrew the cap, add water to the indicated line, and hang. The trap’s no-mess design lets you close the lid and discard the entire bag when it’s full, avoiding hand contact with flies or liquids.

• No mixing or measuring required—just add water
• No emptying; seal and throw the bag away
• Hang with the included tab or a hook for quick placement

Where should I place the bag for the best results?

Place traps where flies frequent but out of direct human activity: near animal pens, trash bins, compost, or property perimeters. Choose a sunny, open spot and keep the bags 20–30 feet from doors, patios, and play areas so the attractant pulls flies away from people.

• Place downwind of seating or entryways
• High-traffic fly zones like dumpsters and stalls work best
• Use multiple bags to create a protective ring around structures

Who is this for? Catchmaster Disposable Outdoor Fly Traps are designed for homeowners, farmers, and property managers who need a low-effort, high-capacity solution for fly control. They’re ideal for large yards, barns, kennels, garbage enclosures, and any outdoor area where flies gather and conventional sprays are impractical. With eight ready-to-use bags per pack and a simple add-water setup, these traps are suited for anyone wanting fast deployment, minimal maintenance, and no-contact disposal.
