Best Mosquito Traps

The Spruce / Chloe Jeong

Nothing can ruin a perfect day outside like the relentless buzzing of mosquitoes and the constant swatting that ensues once the biting begins.

Mosquito traps are one way to tackle this pest problem. They’re designed to lure mosquitoes by mimicking human breath, or carbon dioxide, which is how mosquitos target humans (in addition to the scent of their skin). The traps then use either adhesive glue, electric zap, dehydration, or drowning to kill the mosquitoes. This can be effective when you are attempting to eliminate these pests from a specific area like a backyard or a bedroom.

And, since only female mosquitoes can bite, catching them the moment they’re looking for blood will prevent them from reproducing. While traps may not be able to completely eradicate your issue, they can make a big difference if you place them in the right location and run them every day. We rounded up the most effective mosquito traps on the market from budget-friendly to portable.

Here are the best mosquito traps to keep pests away.

Best Overall: Dynatraps DT1050-TUN Insect and Mosquito Trap

Dynatrap DT1050-TUN Insect and Mosquito Trap Twist On/Off

For a mosquito trap that can do it all, pick up the Dynatrap. This powerful trap not only covers large indoor and outdoor spaces, but is also portable and effective.

Their Insect and Mosquito Trap offers what they consider “3-way protection”. First, the unit uses UV light and carbon dioxide to lure mosquitoes to a whisper-quiet fan. Then, the fan vacuums the mosquitoes into a chamber where they meet their ultimate demise.

Unlike comparably effective models, Dynatrap’s lantern-style unit is completely free of pesticides and chemicals. It also features a unique twist-on and off feature to ensure no pests can escape even once the unit is turned off. For maximum efficiency, Dynatrap recommends using the trap for a full six weeks to break the breeding cycle. 

Best for Outdoors: Flowtron BK-15D Electronic Insect Killer

Flowtron BK-15D Electronic Insect Killer

Nothing spoils a backyard gathering more than a bunch of relentless mosquitos. If you’re looking to tackle a larger area like the outdoors, you’re going to want an insect killer that can go the distance. Flowtron’s Electronic Insect Killer is our pick for the best outdoor mosquito trap.

This trap doesn’t use pesticides, propane, or glue, and is effective for a radius of up to half an acre. It uses a 15-watt ultraviolet light and an optional octenol mosquito attractant cartridge that can be replaced every 30 days. (Octenol is a pesticide ingredient that is not harmful to humans.) The attractive lantern-like design blends in with surroundings but is also weather-proof. For best results, place the trap 25-feet away from any area used for gatherings and comes with a 9-inch cord for mounting. 

Best UV: Gardner Flyweb Classic Fly Light

Ideal for small to medium-sized indoor spaces and enclosed patios, Gardner’s Flyweb Classic Fly Light attracts mosquitoes and other pests with UV light. Simply plug the unit into an electrical outlet, and watch as the light attracts pests to a glue-board adhesive that can easily slide out for simple disposal and replacement.

The compact size of Gardner’s UV trap and inconspicuous design makes it easy to hide in any room where you have a pest problem. To use, remove the protective coating on the adhesive board and insert it into the unit, then plug the unit into your outlet and you’re all set. For maximum effectiveness, replace the adhesive strips once a month and replace the UV light annually.

Best Portable: Katchy Indoor Insect and Flying Bugs Trap

Katchy Indoor Fly Trap

There is only so much that a citronella candle can do. So when you’ve given up on the au natural approach to pest-free living, it’s time to give Katchy’s Electric Insect Trap a try. This portable bug trap can tackle more than just mosquitos—it also handles gnats, fruit flies, and moths.

The trap works by luring insects with a UV light, then to a fan that sucks them down into the machine, and lastly to a glue trap at the bottom. The fan prevents them from generating enough lift to escape, while the glues immobilizes them until they perish.

The unit weighs only 1.5 pounds, making it easy to pack along for camping and other outdoor trips. For best results, use the device with all of the lights off for at least three consecutive nights.

Best Wall Mounted: DynaTrap DT1100 Insect Trap with Optional Wall Mount

DynaTrap Wall-Mounted

Dynatrap is no stranger to high-quality and durable traps that stand up to weather elements. That's why we recommend their Wall Mount Insect and Mosquito Trap, a chemical-free, weather-proof trap that is sure to get rid of flying pests.

Similar to their standard model, this unit also offers three-way protection for up to half an acre. The fluorescent UV bulb produces a warm light, while a titanium dioxide-coated surface releases CO2 to mimic the lure of humans. A whisper-quiet fan pulls and traps the insects inside a catch basket located at the bottom of the unit without zapping them, where they eventually die. While this model is durable enough to withstand extreme weather conditions outside, it can also be mounted inside or hung with an included chain.

Best Paper: Kensizer 30-Pack Dual-Sided Yellow Sticky Gnat Traps

For just two dollars per sheet, you can go the old-fashioned route and hang a dual-sided sticky trap to get rid of your mosquito problem. These paper traps are designed for flying pests like mosquitoes and gnats. They’re much more affordable than standard plug-in mosquito traps, and reduce the use of chemical insecticides.

Easily portable, these 6 x 8-inch sticky yellow paper traps work for both indoors and outdoors. They’re waterproof, UV-resistant, and long-lasting, meaning they can be left outside in a garden or on a patio for an extended period of time and still remain effective. The dual-sided feature allows them to cover more space, and clean-up is as easy as can be. Simply throw away once they are covered and replace.

For best results, hang these traps during the start of the seasons, before pests begin to multiply.
