What a Killer Concept!

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, featuring an ultraviolet (UV) light that insects can’t resist. They pass through an electrified wire grid that—bzzzt!—kills them on contact. Dead bugs then drop into a collection tray, which can be emptied as often as needed (usually two to seven days, depending on the prevalence of pests).

Choosing a Bug Zapper

Power Particulars

Here are the different types of bug zappers you’ll find on the market today.

  • Plug-in zappers: The majority of bug zappers are powered by electricity, so you’ll need an exterior outlet if you plan to put one outdoors. Alternately, you can use an extension cord—just ensure that it’s labeled for outdoor use. Indoor zappers plug into an interior outlet.
  • Battery operated zappers: Intended for camping, tailgating, and other outdoor activities where electricity isn’t available, these lightweight, portable zappers can be hung in trees or set on a table. Racquet-type zappers (swing them at insects as you would a flyswatter) operate exclusively on batteries.
  • Solar zappers: The newest, most versatile zappers are solar powered. They can be used at home or on the go—just position them in sunlight during the day to charge their internal batteries, and they’ll automatically turn on a dusk and start zapping flying pests.

Shock Value

The electrified grid in today’s 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 flyswatters,” are 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 the bug—they’re zapped. Touching the grid when the button is depressed will also give the user a shock, so take care when using a swatting-type zapper, and remind kids that they’re not toys.

Bait Those Biting Bugs

Many flying insects are attracted to light, but a recent University of Delaware study found that bug zappers kill fewer biting bugs, such as mosquitos and biting flies, than such non-biting insects as flying beetles and moths. If you want a bug zapper to kill mosquitos, amp its effectiveness with bait containing octenol, the chemical found in human breath and sweat that mosquitos find irresistible. Octenol—sold under the labels “mosquito bait” and “mosquito attractant”—comes in small packed lures that adhere to the inside of the zapper’s collection tray. One lure attracts mosquitos for up to three months.

Outdoor vs. Indoor Zappers

While they perform the same function, outdoor zappers are designed to withstand the elements and are often bigger with larger collection trays. Indoor zappers often feature white UV lights, as opposed to the deep purple color seen in outdoor zappers, a color many people find distracting. Some bug zappers can be used either indoors or outdoors, so check the label before buying.

Coverage Area Concerns

When shopping for an outdoor zapper, you’ll find a coverage area listed, often by acreage. While there are no industry standards, typically, the UV lights in the zappers with the greatest coverage are brighter so they can be seen by bugs from a greater distance. The U.S. Environmental Protection Agency lists bug zappers as “pesticide devices,” and 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.
