Flybuster Outdoor Fly Trap for Chicken Coops and Barns
Flybuster is a passive, baited outdoor fly trap for use around chicken coops, barns, stables, farms, gardens, waste areas, and other places where common flies gather. The activated bait draws flies toward the container, and the one-way lid openings or side cones are designed to retain them inside.
This is an outdoor-use product. The bait develops a strong, pungent odor as it activates, so the trap should be positioned away from the coop, home, patio, doorway, or other occupied area you want to protect. Correct placement helps direct fly activity toward the trap instead of toward people and animals.
Choose Compact, Garden, or Commercial
| Size | Container volume | Suggested setting | Manufacturer-rated capacity |
|---|---|---|---|
| Compact | 1 L | Small coop perimeters, gardens, patios, campsites, and waste-bin areas | Up to 10,000 flies |
| Garden | 2 L | Chicken coops, barns, stables, gardens, and moderate outdoor fly activity | Up to 40,000 flies |
| Commercial | 10 L | Farms, livestock areas, large barns, work sites, and heavier fly activity | Up to 2,000,000 flies |
The capacity figures above are manufacturer ratings for the containers, not guaranteed catch totals. Actual performance and service time vary with fly pressure, weather, temperature, placement, bait condition, and how quickly the trap fills. Choose a size based on the area, expected fly activity, available placement distance, and how often you can inspect the trap.
How the Flybuster Baited Trap Works
Water activates the bait and starts a fermentation process that produces the odor used to attract flies. Compact and Garden traps use entry points in the lid, while the Commercial container uses side cones. Once flies pass through an entry opening, the design makes it difficult for them to leave the container.
The manufacturer describes the bait as fermented yeast-based and formulated without insecticides. Always rely on the current product label and package directions for ingredients, permitted uses, handling, and disposal. Do not treat the trap as universally harmless, odorless, maintenance-free, or appropriate for indoor use.
Setup and Water Amounts
Read the directions supplied with your trap and bait packet before opening or mixing. Current manufacturer guidance lists the following water amounts:
- Compact: Add 16 oz of water to a 25 g Compact refill packet.
- Garden: Add 32 oz of water to a 50 g bait packet.
- Commercial: Add 10 pints, or approximately 1.5 gallons, of water to a 250 g Commercial refill packet.
- Inspect the trap, lid or cones, bait packet, and closure before use.
- Add the water quantity specified for the trap and bait size.
- Close the container securely and gently swirl it to mix.
- Current manufacturer instructions call for keeping the trap closed for 48 hours while the bait activates.
- After activation, open or position the entry system exactly as directed on the current package.
If the directions packed with the product differ from the website guidance, follow the current package directions. Do not add extra bait, substitute another attractant, or overfill the container.
Outdoor Placement Around a Chicken Coop
Current manufacturer guidance recommends placing the trap about 20 feet from the building or area being protected and approximately 5 feet above the ground. When multiple traps are used around a large area, the manufacturer recommends spacing them about 45 feet apart around the perimeter.
- Keep the activated trap outside rather than inside the chicken coop.
- Position it away from doors, walkways, patios, feed storage, and frequently occupied areas.
- Hang or support it securely where poultry, pets, children, and wildlife cannot tip or disturb it.
- Check that the lid and entry openings remain correctly positioned after storms, servicing, or relocation.
Placement may need adjustment as wind, shade, temperature, moisture, manure accumulation, and seasonal fly pressure change. Inspect the area and follow all label restrictions.
Use as Part of Chicken Coop Fly Management
A baited trap addresses adult flies but does not replace sanitation or moisture control. Remove manure and spilled feed, repair water leaks, keep bedding as dry as practical, clean wet areas, and manage waste before it becomes a breeding site. Combining prevention with correctly placed outdoor traps is more useful than relying on a trap alone. For seasonal cleaning steps, see our summer coop cleaning tips to reduce flies and odor.
Do not place the attractant next to nest boxes, feeders, drinkers, or the coop entrance. Do not feed captured flies, larvae, liquid, bait, or other trap contents to chickens or other animals.
Inspection, Refills, and Disposal
Inspect the trap regularly and service it before it overfills. The useful bait period can vary, and current Flybuster web pages provide conflicting duration guidance for some sizes. For that reason, use the service interval printed on the current bait packet and replace or refresh the bait when directed, when the trap is full, or when performance declines.
- Use only the refill packet intended for the selected Flybuster size.
- Avoid breathing vapors or allowing liquid or bait to contact eyes and skin.
- Use adequate outdoor ventilation, wash hands after handling, and follow any protective-clothing directions on the package.
- Keep the trap closed while moving it and prevent spills.
- Clean, refill, or discard the container only as directed for that model.
The expected pungent odor is part of how the attractant works; it is not evidence that the trap should be moved indoors. Follow local requirements and the product directions when disposing of bait, liquid, captured insects, or the container.
What to Expect
Flybuster can help manage outdoor fly activity when the correct size is activated, placed, and serviced as directed. It does not guarantee complete fly control or a specific number of future flies. Results vary, and ongoing coop cleaning, moisture management, waste removal, and routine inspection remain essential.

Flybuster Outdoor Fly Trap FAQs
Which Flybuster size should I choose?
Choose Compact 1 L for a smaller coop perimeter, garden, patio, campsite, or waste-bin area; Garden 2 L for a chicken coop, barn, stable, or moderate outdoor fly activity; and Commercial 10 L for farms, livestock areas, large barns, or heavier fly activity. Manufacturer-rated capacities are comparison figures, not guaranteed catch totals.
Can I use Flybuster inside a chicken coop?
No. Flybuster is intended for outdoor use because the activated bait produces a strong, pungent odor. Place the trap outside and away from the coop, doors, walkways, patios, feed storage, and other occupied areas.
How far from the chicken coop should I place the trap?
Current manufacturer guidance recommends placing the trap about 20 feet from the building or area being protected and approximately 5 feet above the ground. For multiple traps around a large perimeter, the manufacturer recommends spacing them about 45 feet apart. Follow the current package directions if they differ.
How much water should I add?
Current manufacturer guidance calls for 16 oz of water with a 25 g Compact bait packet, 32 oz with a 50 g Garden packet, and 10 pints, or approximately 1.5 gallons, with a 250 g Commercial packet. Always use the amount printed on the current bait packet if it differs.
How long does Flybuster take to activate?
Current manufacturer instructions call for closing the container, gently swirling the water and bait, and keeping the trap closed for 48 hours while the bait activates. After activation, open or position the entry system exactly as directed for that model.
How long does the bait last, and when should I refill it?
Service time varies with trap size, weather, temperature, fly pressure, placement, and how quickly the container fills. Because current manufacturer web pages provide conflicting duration guidance for some sizes, follow the service interval on the current bait packet. Service the trap when directed, when it is full, or when performance declines.
Is a strong odor normal?
Yes. Fermentation produces the pungent odor used to attract flies, which is why Flybuster is an outdoor-use trap. An odor is expected after activation; move the trap farther from occupied areas if necessary while continuing to follow the placement directions.
Is Flybuster safe to use around chickens?
Use the trap only as directed and position it where chickens, pets, children, and wildlife cannot tip or disturb it. Avoid contact with bait or liquid, wash hands after handling, and follow the current label. Do not feed captured flies, larvae, bait, liquid, or other trap contents to chickens or other animals.
