What Are Bug Zappers?

Bug zappers are electric devices for killing flying bugs. They can be manufactured as hanging lanterns, plug-in night lights, heater-like panels that sit wherever you place them, or handheld devices that you swat the mosquitoes with.

How Do Bug Zappers Work?

Bug zappers consist of a UV light, an electric power source (cord or battery), and a metal grid. The UV light attracts mosquitoes. When they see it, especially at night, they are attracted to it just like the bugs you see flapping around football stadium lights.

The electrified grid or mesh sits in front of the UV light source. When the bugs encounter the grid they are electrocuted by it, producing the characteristic snap, crackle, and pop associated with bug zappers. A tiny spark of light usually accompanies the pop when a flying pest is killed.

The dead bugs that are killed by the zapper, fall into a catch tray at the bottom of the zapper. In the case of handheld bug zappers, the dead bugs simply fall to the ground wherever you killed them.

Bug Zapper Facts

Are Bug Zappers Effective?

This is where it gets a bit dicey. Without exception, researchers all advise people not to use bug zappers – for mosquitoes.

The reason is that mosquitoes are more attracted to heat and carbon dioxide than to UV light. Since people emit body heat and carbon dioxide, we’re more attractive to them than the bug zapper is.

Mosquitoes can detect carbon dioxide, created when we exhale, at levels as small as 50 parts per million. They may be attracted to the UV light from the bug zapper, but as soon as they detect our exhaled carbon dioxide, they change direction and head for us.

Even Octenol packets, which contain a chemical that mimics human breath, can’t compete with the real thing as an attractant. Given a choice, mosquitoes pick us every time.

Bug zappers kill huge numbers of non-mosquito bugs though because many of them are attracted by UV light. Research has demonstrated that mosquitoes are only 4.1% - 6.4% of the total number of insects killed each year by bug zappers. The rest are other flying insects.

If you’re buying an electric bug zapper to kill mosquitoes, it won’t be as effective as you’re hoping it will be. If you’re buying a bug zapper to kill flying pests such as moths, gnats, fruit flies and so on, then you’ll be well satisfied with the results you get from it.

How to Use Bug Zappers

There are two main types of bug zappers; stationary zappers and handheld ones. Each type is used differently.

  • Stationary

The stationary bug zappers can either be the plug-in type or run on batteries, which are often rechargeable ones. These are the ones with a black light in them, either from a light bulb or LED light. They lure and kill insects who are attracted to ultraviolet light.

Some of them are designed exclusively for outdoor use and general pest control while others are only meant to be an indoor bug zapper. Some of those actually double as a night light as well as an insect killer.

  • Handheld

A handheld bug zapper, sometimes known as an electric fly swatter, typically looks like a tennis racket. When you see a flying insect headed your way, just grab it and swat them.

You don’t have to mash them against a hard surface the way you do with a regular fly swatter because in places of strings in the “racket” there is another electrified grid. This turns it into an electronic bug zapper for killing bugs in midair.

You can use handheld bug zappers inside for insect control or use it as an outdoor bug zapper. Because you can pick and choose what to swat, you can kill a large number of insects without killing beneficial insects in the process. You get a bug zapper you can aim.
