RESCUE! Big Bag Fly Trap - 10-Pack Disposable Outdoor Traps, Water-Activated Heavy-Duty Capture

RESCUE! Big Bag Fly Trap is a disposable, water-activated outdoor trap designed to capture large numbers of flies—up to tens of thousands—when hung in yards, barns, or other outdoor areas.

If flies are overwhelming an outdoor area, this ready-to-use trap offers a low-effort, high-impact option. Each bag contains a bait system that lures flies through a one-way entrance; once inside they cannot escape and succumb in the liquid. The product is intended for outdoor use only and is simple to deploy: expose the entrance, add water to activate the bait, and hang the bag where flies concentrate but at least 20 feet from living spaces to minimize odor indoors.

How quickly does the RESCUE! Big Bag Fly Trap begin working?

The trap starts attracting flies shortly after activation—once water is added the bait releases its scent and begins drawing flies to the one-way entrance. You’ll typically see activity within a day in areas with existing fly pressure, with capture numbers increasing over the following days.

• Activate by adding water—no mixing required.
• Visible captures often within 24 hours in active areas.
• Designed to accumulate large numbers over several days.

Where should I place the traps for the best results?

Position traps where flies congregate—near animal pens, trash areas, or sunny fence lines—while keeping them at least 20 feet from homes, patios, or indoor spaces because of the bait’s odor. Hang traps 3 to 6 feet off the ground in sheltered spots with good airflow to help disperse the attractant and keep the bags from being blown around.

• Hang 3–6 feet high in fly-prone locations.
• Keep a minimum 20-foot distance from living areas.
• Avoid enclosed or windy exposed spots to reduce spillage and maximize scent plume.

How many flies will one trap catch and how long does it last?

Each bag is formulated for heavy-duty capture and can contribute to removing thousands of flies from the environment when used properly. Lifespan depends on local fly pressure and weather; in high-infestation settings a trap can collect large numbers within days, while cooler or low-activity conditions slow catches.

• Effective for heavy fly problems—capable of high cumulative captures.
• Performance varies with temperature, humidity, and fly population.
• Replace traps when full, damaged, or when odor becomes a concern.

Is the trap safe and easy to dispose of?

The RESCUE! Big Bag Fly Trap is a single-use, disposable product that requires just water to activate—no sprays or mixing of chemicals. After use, tie or seal the bag according to the package directions and discard in accordance with local waste guidelines.

• No active sprays required—activates with plain water.
• Single-use bag designed for simple sealing and disposal.
• Follow local waste rules for disposal of insect-capture products.
