Zevo Flying Insect Trap & 3 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
78805 reviews
The Zevo Flying Insect Trap is an electric plug-in device designed specifically to catch indoor gnats, fruit flies, and house flies. It uses a combination of blue and UV light to attract insects around the clock, which helps cover most indoor areas where these pests appear. One of its strongest points is the mess-free design: insects get stuck on a disposable adhesive cartridge, so you never have to touch the bugs. This makes it very user-friendly and hygienic.
The trap is compact and can fit easily into any standard wall socket, making it convenient to place in kitchens, bathrooms, bedrooms, or near indoor plants. It includes three refill cartridges, allowing for extended use without immediate extra purchases. In terms of safety, since it uses light and adhesive rather than chemicals or zapping grids, it's safe to use around children and pets. The device produces no noticeable odor, which is a plus for indoor use.
However, the Zevo trap is limited to flying insects that are attracted to light and may not catch all gnats in larger or heavily infested rooms. It also requires regular cartridge replacement to maintain effectiveness, which is an ongoing cost to consider. While easy to use and maintain, some users might wish for a larger coverage area or stronger suction. This trap suits people seeking a quiet, chemical-free, and low-maintenance solution to small indoor gnat problems.

Zevo 2 Flying Insect Traps & 2 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 to catch gnats, fruit flies, and houseflies indoors using blue and UV light, which works around the clock to attract flying insects. Its coverage is suitable for various indoor areas like kitchens, bathrooms, and patios, making it versatile for common spots where gnats appear. A major plus is its mess-free disposal system: the bugs stick to adhesive cartridges that you simply pull out and toss away, so you never have to touch the insects directly. This makes it very user-friendly and hygienic. Safety-wise, it doesn’t use zapping or chemicals, which is good for homes with kids or pets.
The device plugs into standard outlets, so it’s easy to set up and doesn’t require complicated installation. It operates quietly and without producing any harsh odors, which is a big plus for indoor use. While it helps reduce flying bugs noticeably, it might be less powerful in very large or heavily infested spaces.
Since it relies on adhesive pads, these need regular replacement to maintain performance, which adds ongoing cost. Also, it’s designed to catch flying insects near the plug area, so bugs elsewhere might not be attracted. For those seeking a safe, simple, and low-maintenance way to reduce gnats and similar bugs indoors, Zevo 2 presents a solid, chemical-free option that’s easy to use and maintain.

Safer Home Indoor Plug-in Fly Trap - SH502-2SR - Effective Fruit Fly Traps for Indoors, Gnat Traps for House Indoor, 800 Total Sq Ft Protection - 2 Devices + 2 Glue Cards
Most important from
5689 reviews
The Safer Home Indoor Plug-in Fly Trap is designed to control gnats, fruit flies, and other small flying insects inside your home. It uses UV LED light to attract bugs, trapping them on glue cards without any chemical sprays, which makes it a safe choice for homes with kids and pets. The device covers up to 800 square feet, suitable for average-sized rooms or kitchens where these pests are common. Its plug-in design is compact and can rotate to fit different outlets, making it easy to set up and use almost anywhere indoors.
Because it works continuously once plugged in, you get round-the-clock protection from flying insects. Many users report it quickly reduces bug presence, showing good effectiveness. On the downside, like most glue traps, it relies on sticky cards that need replacing, which adds some ongoing cost and maintenance. Also, while it doesn’t use chemicals, some people may notice a slight glue odor, although it’s generally not strong or unpleasant.
This product is ideal if you want a low-maintenance, child- and pet-safe insect trap that quietly works in the background without sprays or toxins. If you prefer something that doesn’t require outlet access or regular card changes, other options might suit you better. For safe, effective indoor gnat and fly control, this plug-in trap offers a solid balance of convenience and performance.
