78805 reviews
The Zevo Flying Insect Trap is designed specifically for indoor use against gnats, fruit flies, and houseflies, using blue and UV light to attract insects continuously day and night. It’s a plug-in electric device that uses adhesive cartridges to catch bugs without the mess usually associated with bug zappers. This makes disposal easy and hygienic since you never need to touch the insects directly.
The trap is compact and lightweight, allowing placement in various areas like kitchens, bathrooms, garages, or near plants where gnats and flies are common. It comes with three refill cartridges, providing good value and extended use. In terms of safety, it uses light and sticky pads instead of chemicals or zapping, making it safer for homes with kids or pets. It’s also odor-free, so it won’t leave unpleasant smells in your space.
Its small size makes it most suitable for localized use in rooms rather than large open areas. It functions as a convenient, low-maintenance option for indoor gnat control, particularly for those seeking a mess-free and chemical-free method.

Zevo Flying Insect Trap Official Refill Cartridges - Fits Both Zevo Trap & MAX Indoor Fly Trap - Authentic Trap+Lock Technology to Catch Gnats, House & Fruit Flies (4 Official Refill Cartridges)
Most important from
39331 reviews
The Zevo Flying Insect Trap Refill is a convenient solution for dealing with gnats and other flying insects indoors. Designed to work with both the Zevo MAX and standard indoor fly traps, this product uses blue and UV light to attract insects, avoiding the need for chemical insecticides. This makes it a safer option, especially for households with children and pets.
The refills are easy to use and feature a strong adhesive backing that ensures mess-free disposal, as you never need to touch the trapped insects directly. Each pack includes four cartridges, providing consistent 24/7 protection when used in any room of your home, from the kitchen to the garage.
However, the product's reliance on specific Zevo devices means it might not be suitable for those who do not already own a Zevo trap. Additionally, while the absence of chemical odors is a plus, those expecting a quick, dramatic reduction in insect populations might need to be patient, as it works continuously over time rather than providing immediate results. If you are looking for a safe, easy-to-use, and effective solution to keep your indoor spaces free from gnats and other flying pests, the Zevo Flying Insect Trap Refill is a solid choice.

Zevo 2 Flying Insect Traps & 4 Refill Cartridges - Plug in Fly Trap & Indoor Bug Catcher for Gnats, House & Fruit Flies - Blue & UV Light Technology, Mess-Free Alternative to Bug Zapper
Most important from
31776 reviews
The Zevo 2 Flying Insect Traps are designed for indoor use, especially effective against gnats, fruit flies, and house flies. They use blue and UV light to continuously attract flying insects, working 24/7 to catch bugs discreetly on adhesive pads. This mess-free approach means you don’t have to touch any insects, which is a big plus for convenience and cleanliness.
The traps plug into regular outlets and can be placed in various indoor locations like kitchens, bathrooms, or near plants, offering versatile coverage that suits different rooms around the home. In terms of safety, the product uses no harmful chemicals or sprays, making it safe for use around children and pets. Users find it easy to operate—just insert the disposable cartridges and replace them when full. However, the coverage area is somewhat limited to indoor spaces near the device, so larger rooms or open areas might require multiple units for best results. While effective for small to moderate insect issues, very heavy infestations may need additional methods.
The product is quiet and odorless, which is ideal for indoor comfort. This trap provides a handy, low-maintenance option for those wanting a non-toxic and tidy way to reduce flying insect nuisances indoors.
