9 Best Fly Trap Outdoors 2025 in the United States

The Flowtron Bug Zapper is an electric insect killer designed for outdoor use, covering up to 1 acre. It's equipped with a powerful 40W UV light bulb and a high-voltage 5600V grid, making it effective in attracting and eliminating various flying pests like flies, mosquitoes, gnats, and moths.

The dual attractant system, which includes a UV light and an octenol cartridge, enhances its ability to lure insects, mimicking animal breath to attract more bugs. This zapper is easy to use—simply hang it on your property, and it operates without the need for messy bags or chemical refills, requiring only occasional bulb and cartridge replacements.

It is environmentally friendly and safe for use around people, pets, and wildlife, given its maintenance-free design and lack of chemical sprays or pesticides. The weatherproof polycarbonate housing ensures durability across different weather conditions, and being UL certified adds a layer of safety assurance. One drawback is that the need for replacing octenol cartridges might be considered an ongoing cost. Additionally, while it efficiently zaps bugs, it doesn't collect the dead insects, which might necessitate occasional ground cleanup. Despite these considerations, it is a reliable choice for those needing extensive outdoor insect control.

The Outdoor Fly Trap [2 Pack] offers an effective solution for controlling flies. It's designed with a dissolvable non-toxic bait, making it safe around children and pets. The trap effectively lures and drowns flies using a powerful bait with a strong odor, which is very efficient in attracting various fly species. The product is user-friendly, requiring just water and the included bait to set up. It's suitable for hanging outdoors and works best when placed away from sitting areas due to the strong smell.

One significant advantage is its fast-acting nature, with users needing to set it up just 5 hours ahead of use. On the downside, the water in the trap may evaporate quickly in hot weather, necessitating frequent refills to maintain its effectiveness. Durability is decent, but handling the trap when it's full can be messy and requires gloves. The product is not reusable without thorough cleaning, which can be inconvenient.

Still, for those dealing with a serious fly problem outdoors, this trap provides a powerful and relatively easy solution.

The Rescue! Outdoor Disposable Hanging Fly Trap is a simple and effective solution for controlling flies in outdoor spaces. It uses a scent-based attractant that draws flies inside, where they drown in water, making it a chemical-free option that avoids the mess of cleaning up dead insects. The trap’s hanging style allows you to place it around your yard or garden, but it should be positioned at least 20 feet away from any living areas due to a strong odor once activated.

This product comes as a pack of six traps, offering good coverage for moderate outdoor use. It’s very easy to use—just add water to start the bait and hang it up, then dispose of the trap when full, which is convenient for those seeking low-maintenance pest control. However, since the traps are disposable, they are single-use, which may not be ideal for those wanting a more durable or reusable option. The product is lightweight and compact.

Because it contains no electric parts or toxic chemicals, it’s safe to use around children and pets, provided it’s hung out of reach. With its strong attractant, ease of setup, and positive customer feedback, Rescue! is a reliable choice for people who want a straightforward, no-fuss fly trap for typical outdoor areas.
