Rescue Big Bag Fly Trap: Industrial-Scale Fly Control for Montana Operations

The Rescue Disposable Outdoor Big Bag Fly Trap holds up to 40,000 flies per bag — that’s not a typo. Standard disposable traps hold around 2,000-5,000 flies. This trap brings commercial-grade capacity to Montana’s barns, livestock areas, and agricultural operations where fly pressure goes beyond what standard traps can handle.

The trap transforms from 7.75” x 3.25” x 11.5” packaged to 18” x 12” x 8” when expanded. EPA registration #84565-2-49407 confirms it uses non-toxic, pesticide-free attractant — critical for operations around food production and livestock.

Performance That Matches Montana’s Agricultural Demands

The water-activated lure pouch starts working immediately. No mixing chemicals, no handling toxic baits. Fill the bag with water up to the marked fill line and the non-toxic food and feed-grade ingredients activate on contact.

Target species include house flies, false stable flies, blow flies, blue and green bottle flies, flesh flies, and face flies. The catch: it does NOT catch biting flies such as stable flies or horse flies. Know the difference before buying — biting flies require different control methods.

The entire unit is safe for use around children and pets when used as directed, making it practical for mixed-use properties. Animal pens and livestock areas including poultry, hog, sheep, dairy, and beef cattle are prime placement locations.

Critical Installation Requirements

Here’s where contractors save callbacks: the trap must be used outdoors only and recommended to hang at least 20-30 feet away from living spaces (patios, decks, home entrances) to avoid the strong attractant odor. That smell isn’t optional — it’s what brings the flies.

Hang outdoors 20+ feet away from living areas in a sunny location. The sun accelerates attractant dispersal and fly activity. Barns and stables, garbage bins, dumpsters, compost piles, dog runs and kennels make ideal placement spots.

Installation takes minutes:

1. Remove trap from package and cut or pull up the yellow top cap along the dotted line
2. Attach included hanging strap
3. Fill bag with water up to the marked fill line
4. Hang outdoors 20+ feet away from living areas in a sunny location

Real-World Performance Data

Multiple retailers report consistent satisfaction. Amazon: 4.5 stars, Home Depot: 4.6 stars, Tractor Supply: 4.6 stars, DoMyOwn: 5 stars. Users praise “extremely effective at reducing fly populations quickly” and “cost-effective solution for large-scale fly control”.

The documented weaknesses matter: “strong, unpleasant odor required for lure” and “potential for bag leaks or seam failure under heavy load or wind”. Montana wind can stress any hanging bag — secure placement prevents failures.

Bottom Line for Montana Operations

The 40,000-fly capacity significantly exceeds standard traps that hold 2,000-5,000 flies. For operations dealing with serious fly pressure — cattle operations during peak season, horse barns, commercial composting — that capacity difference translates to fewer replacements and better control.

Retailers offer standard return policies: Home Depot provides 90-day returns, Amazon offers 30-day voluntary return guarantee. Sterling International, Inc. manufactures the trap in the USA.

The odor complaint isn’t a defect — it’s the mechanism. Contractors installing these need to explain the 20-30 foot setback requirement clearly. Position these correctly around Montana’s agricultural operations and they deliver industrial-scale fly reduction without pesticides.
