10 Best Outdoor Fly Traps 2025 in the United States

The Flowtron Bug Zapper is an electric insect trap designed for outdoor use, offering one acre of coverage. Its main strengths lie in its powerful 40W UV light and a 5600-volt instant killing grid, which work together to attract and eliminate a variety of flying pests, including mosquitoes, flies, gnats, beetles, and moths. The inclusion of an Octenol attractant enhances its effectiveness by mimicking animal odors to lure more insects. This combination of UV light and attractant sets it apart from simpler traps that might rely on just one method of attraction.

The kill grid is designed to be non-clogging and maintenance-free, which means you don’t have to deal with messy bags or tanks. Occasional bulb replacements and Octenol cartridges are the main upkeep tasks required, making it relatively low maintenance. The weatherproof ABS housing ensures durability and reliable performance across different weather conditions, adding to its longevity and ease of use.

However, the unit's weight (4.84 pounds) and dimensions (8.5 inches in length, width, and 13.5 inches in height) might make it less portable compared to smaller traps. It also requires a power source, which might limit placement options if an outlet isn't nearby. Furthermore, while the zapper is effective in killing insects, it can be slightly noisy when bugs are electrocuted. This might be a minor inconvenience for some users. Nonetheless, for those seeking a robust and low-maintenance solution to outdoor insect problems, the Flowtron Bug Zapper is a strong contender.

The RESCUE! Outdoor Disposable Hanging Fly Trap is a user-friendly solution for controlling flies in outdoor spaces. The trap is designed to attract flies using a bait that lures them into drowning in water. Setting it up is straightforward: you simply add water to the bait and hang the trap at least 20 feet away from living areas. This distance is crucial due to the strong odor that can be unpleasant if too close to living spaces.

The product's disposable nature makes it hassle-free—once full, you just discard the entire trap. This pack includes eight traps, which means you can cover a significant area over time or place traps in multiple locations simultaneously. The traps are lightweight and made from plastic, contributing to their ease of use and portability. However, because they are disposable, they may not be the most environmentally friendly option.

If the odor is a concern or if you need a trap for indoor use, this product might not be the best fit. They are proudly made in the USA, which may appeal to those looking for domestically manufactured products. This fly trap is effective and easy to use, ideal for those needing a quick and straightforward outdoor fly control solution.

The Flowtron Bug Zapper is a powerful outdoor fly trap designed to cover up to 1.5 acres, making it ideal for large backyards, patios, and farms. It uses two high-intensity UV lights and octenol cartridges to attract flying insects, and a 5600-volt grid for instant extermination. This combination of attraction methods ensures effective pest control, significantly reducing the number of flies, mosquitoes, and other flying insects in the coverage area.

One of its major strengths is its ease of use. Simply hang the zapper, and it requires minimal maintenance—just occasional replacement of UV bulbs and octenol cartridges. Another plus is its environmentally friendly design, as it avoids chemical sprays and pesticides, making it safe around people, pets, and wildlife.

The zapper is also weatherproof and made with durable polycarbonate housing that resists rust, cracks, and fading, ensuring longevity through various weather conditions. Its high-voltage grid might be overwhelming for smaller outdoor spaces and could be seen as overkill if you don’t have a severe insect problem. Additionally, the initial setup might be a bit cumbersome due to its size and the need to hang it in an optimal spot. Despite these minor drawbacks, the Flowtron Bug Zapper offers a powerful and reliable solution for those dealing with large areas plagued by flying insects.
