7 Best Bug Zappers

The Tysonir Electronic Bug Zapper is strictly for indoor use. This AC-powered model can rest on a table or hang from a wall or ceiling. It’s easy to access and clean the removable collection tray.  (Tysonir makes indoor/outdoor zappers, as well.)

It relies on UV light to attract bugs, so consider adding a mosquito lure to make it more effective against those pests (recommendations below). Note: This zapper is not waterproof.

To convert a traditional zapper into a mosquito-killing machine, you’ll need an octenol lure to draw in those biting pests. Here are two great options to consider:

DynaTrap Atrakta Mosquito Lure: This drops into the collection basket of any zapper and gives out enough attraction to last for about 60 days.

Black Flag Mosquito Octenol Lure: This clip-on bait cage was made for Black Flag’s zappers but fits on most other units as well. It lasts about 30 days so it must be replaced more often than the DynaTrap, but it’s about one-third the price.

What to Consider When Buying Bug Zappers

Bug zappers typically feature two sets of grids surrounding a light. The outer grid is for safety — plastic or grounded metal bars that prevent humans or pets from getting zapped. The electrically charged inner grid carries enough power to kill insects that encounter it. The light in the center attracts the bugs.

Many zappers combine visible and UV light. Those work great on moths and gnats, but not mosquitos, which are attracted by carbon dioxide and warm moisture. You’ll need a chemical bait or lure like octanol or titanium dioxide (TiO2) for mosquito control.

Some key considerations when shopping for a bug zapper include:

• The bait: A UV light is the only lure you’ll need for most flying insects. “Most bug zappers have a light designed to attract flying insects in the UV light spectrum and the most attractive is between 300-420 nm,” says Price. “Also, ensure there is an electronic grid to zap the insect once drawn by the light.”  But to be effective against mosquitos, you must appeal to their senses. If a zapper doesn’t come with a mosquito attractant, don’t worry! You can add your own bait to most zappers. (See the last slide for two recommended bait products.)
• Clean-up: Does the zapper let the bug debris fall to the ground, or collect it in a tray for easy disposal?
• Noise: How loud is the zapper, normally and when a bug hits it? Most models don’t include a decibel (dB) rating, so look for ones that brag about their quiet operation.
• Power source: Most use AC power. But battery-operated, rechargeable and solar-powered models are making headway into the market.
• Usage: There are plenty of options for placing and using a bug zapper. Some rest on a table while others hang overhead. Some are even built like mini-tennis racquets and act as swatters!
