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 Black Flag Fly Stick is designed to trap houseflies and other flying insects both indoors and outdoors. It's easy to use - simply add honey or syrup to attract flies. The pack includes six sticks and hooks for hanging, which makes setup straightforward and effective.

The design ensures that once insects land on the stick, they won't be able to escape. This fly stick is not electric, which makes it a safe option for use around children and pets. The product is lightweight and made from paper, offering decent durability for general use.

Its coverage area depends on placement and attractant efficacy, but it's suitable for areas like patios or picnic spots where flying insects are a nuisance. It may not be ideal for larger infestations or extensive outdoor areas as its reach is somewhat limited. The product’s materials and safety features make it a practical choice for casual use but might require regular replacement in highly infested areas due to its non-durable material.

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.
