What to Consider When Choosing the Best Bug Zapper

Bug zappers have been around longer than you probably think. An early prototype featured an electric light and a chunk of bait encased within an electrified cage. Insects, attracted by the light and bait, were electrocuted when they touched the cage.

Many of the best bug zappers today work on the same simple concept. They feature an ultraviolet (UV) light that insects can’t resist. When the bugs try to get to the light, they pass through an electrified wire grid that kills them on contact. Dead bugs then drop into a removable collection tray, which can be emptied as often as needed (usually every 2 to 7 days, depending on the prevalence of pests).

Keep the following factors in mind when selecting the best bug zapper for your indoor or outdoor space.

Power Source

Bug zappers run on a variety of power sources, the majority of which are plug-in electric models. An electric bug zapper will need an exterior outlet if you plan to put it outdoors. Alternatively, you can use an extension cord—just ensure that it’s labeled for outdoor use.

Lightweight and portable battery-powered bug zappers make great companions on camping trips, at tailgate parties, and during other outdoor activities. They can hang in trees or sit on a table. Racquet-type zappers, another battery-operated option, are like electrified fly swatters that shock the bugs you swing at.

The sun powers the newest, most versatile outdoor bug zappers. Just position them in sunlight during the day to charge their internal batteries and switch them on at dusk to start zapping pests at home or on the go.

Outdoor vs. Indoor

While they perform the same function, outdoor zappers are designed to withstand the elements better than indoor ones. They also tend to be bigger and include larger collection trays. Hanging electric bug zapper units are a popular and attractive option for a patio or seating area.

Indoor bug zapper options sometimes feature white UV lights, as opposed to the sometimes-distracting deep purple seen in outdoor models. The best indoor bug zapper products tend to be wall fixtures and countertop units, since they are the easiest to install indoors.

Some types of bug zappers work well both indoors and out, so check the label before buying.

Shock Value

The electrified grid in plug-in and lantern-type bug zappers is safely contained within a plastic cage to prevent fingers from inadvertently touching the grid and receiving a shock. Racquet-type zappers, also called “electric fly swatters,” can be a different story.

Press a button on the tennis racket–type handle to electrify the grid, and then swing the head of the racquet at flies or other insects. If you make contact with bugs, they’re zapped. But beware: Anyone, human or insect, who touches the grid when the button is depressed will get a shock. To prevent accidental zaps, look for a handheld zapper with a protective layer. Keep pets out of swatting range, and remind kids that electric fly swatters are not toys.


Many flying insects are attracted to light, but a University of Delaware study found that bug zappers kill more non-biting insects, such as flying beetles and moths, than they do biters, such as mosquitoes and biting flies.

If you want a bug zapper to kill mosquitoes, amp its effectiveness with bait containing octenol, the chemical found in human breath and sweat that mosquitoes find irresistible. Octenol comes in small packed lures that adhere to the inside of the zapper’s collection tray. One lure attracts mosquitoes for up to 3 months. Or grab a handheld zapper and hunt the mosquitoes yourself. Since you aim with a racket-style zapper, this type of device is an excellent choice for the best mosquito zapper indoors, too.

Coverage Area

When shopping for an outdoor bug zapper, you’ll find a coverage area listed, often by acreage. While there are no industry standards, typically, a larger coverage area means brighter UV lights in the zappers so that bugs see them from a greater distance.

The U.S. Environmental Protection Agency lists bug zappers as “pesticide devices.” While the EPA admonishes manufacturers not to make false claims about their products, they do not regulate the bug zapper industry, so exaggerated claims may occur.

FAQs About Bug Zappers

With the best bug zapper, flying insects are less likely to put a damper on your evening plans. Before selecting a new bug zapper, check out the following frequently asked questions to learn more about these bug-eliminating gadgets.

Q. How do bug zappers work?

Most freestanding or hanging bug zappers attract insects with a bright light and electrocute them with an electrical mechanism once they land.  Electric fly swatters, on the other hand, employ a racquet design with an electrified mesh to zap any bugs in its path.

Q. What kind of bugs does a bug zapper kill?

Bug zappers can kill any bug that comes in contact with their wired grids.

Q. Do bug zappers work in daylight?

An active bug zapper will still kill bugs that come in contact with it during the day. However, their luring rays will not work as effectively in daylight.

Q. Should I leave a bug zapper on all night?

The longer a bug zapper is left on, the more bugs it will trap. It’s best to turn off outdoor bug zappers at night—there’s no need to continue killing bugs once you’ve come inside. However, it is effective to leave an indoor bug zapper on overnight to kill as many bugs within a room as possible.

Q. Do bug zappers use a lot of electricity?

No, bug zappers do not use very much electricity. If electricity use is a concern, opt for a battery-powered or solar-powered zapper.
