Best Bug Zapper (Indoor and Outdoor)

Have you ever heard of bug zappers? Well, they are a kind of device that uses ultraviolet (UV) light to attract insects. Then, the insects will enter its grid, where they are electrocuted and killed once drawn in. Sounds harsh, right?

But actually, bug zappers want to make your life easier and more peaceful by getting rid of annoying insect pests, especially those that give you itchy bites. Still, research shows that bug zappers may not help eliminate mosquitoes, particularly the female ones (that suck blood from humans), since they are not attracted to UV light.

Instead, they keep track of the carbon dioxide emitted by humans through breath, sweat, or body odors. Hence, even if bug zappers kill female biting mosquitoes, they may only be able to kill a small number because most bugs attracted to UV light are considered harmless and innocent.

Nevertheless, it does not mean that bug zappers exist for nothing. They can still be very helpful in some ways, even if they seem to not be that effective in killing mosquitoes. Besides, who says that it is only mosquitoes that can annoy you?

There are a bunch of other insects that can disturb your peace, and bug zappers can help you get rid of all of them. You just have to find the right product!

Best Bug Zappers

If you’re in a hurry, here are links to the bug zappers reviewed in this guide. We go into more detail about them later on in this article.

What is a Bug Zapper?

A bug zapper is an appliance that attracts bugs with UV light. The bugs are drawn to the center of the zapper, where they are electrocuted when they come into contact with metal grids. A tiny gap often separates two grids; when a flying insect touches the two grids, it completes the electrical circuit. With 2000V or more flowing through the insect, it is electrocuted and disintegrates or falls dead into the tray below.

Bug zappers are usually made up of:

  • a metal or plastic exterior casing including a protective grid to stop children and pets from getting electrocuted
  • UV light bulbs often fluorescent or LED
  • Wire girds that surround the light bulbs
  • A transformer that converts 120V into a charge of 2000V or more
  • A collection tray that collects dead insects or insect parts

How to Choose the Best Bug Zapper?

In choosing the best bug zappers, you, of course, have to look into the quality. You can check the description or ask the manufacturer or the one selling in the store what materials it’s made of. Make sure these materials are durable and will ensure the longevity of the bug zapper.

It would be helpful to give it a try first before purchasing it, but of course, this isn’t possible, so it’s worth going through a few of the buyers’ reviews to see what they think. Some of the popular bug zappers have thousands of customer reviews, most of which are positive. But it’s always possible to get a faulty product, so it’s worth checking if the customer service is reactive.

You might also consider if you want an outdoor bug zapper that you hang outside your house, place on a flat surface, or a swatter zapper that looks like a racket, which you can use to go after flying bugs.

Another consideration is the sound the insects make when they are electrocuted. Some people may find this zapping sound annoying or distressing, so you may want a zapper that can be set up away from where people will be gathering or an indoor trap that will work silently.

Another way to choose the best bug zapper is to ask some of your friends what they are using. They may be able to refer you to the best brand of mosquito zapper they know that will not fail you in terms of killing mosquitoes and other insects.

Types of Bug Zappers

There are a few different types of bug zappers to keep your home or yard free of flying pests. They come in various shapes and sizes and can use different power sources.

Hanging bug zappers in the form of a lantern are often used outdoors. Some of these lanterns can be used indoors or outdoors. The bulbs in these zappers are vertical.

Box-shaped devices are usually used indoors; the bulbs are placed horizontally. These zappers can be hung on a hook or placed on flat surfaces.

Handheld bug zappers are in the form of a tennis racket. These racket zappers require some effort as you have to go after the bug that is annoying you. But they are very effective, and some consider chasing and electrocuting insects as a bit of fun.

Socket bug zappers are a sort of mini zapper that plugs directly into an electrical outlet. They work with UV light bulbs to attract insects, and as they have a less powerful electrified grid, they work more silently than the bigger zappers.

Bug Zapper light bulbs screw into light bulb fittings and can give ordinary light or UV light that attracts the bugs into the bulb, where there are killed by an electrified grid.

What to Look For in a Good Bug Zapper?


Effectiveness is one of the things you need to look for in a good zapper. Does it have enough high voltage to kill insects and not just stun them? Are they proven to kill insects or eliminate only those innocent and harmless insects but not the biting ones? That is something you must consider.


Also, you need to look for convenience. Is it high maintenance? A good bug zapper must also be easy to clean. There are a lot of bug zappers that contain removable and washable trays for you to quickly and effortlessly remove the dead insects electrocuted by the device.

Whatever bug zapper you choose, make sure you understand the maintenance needed. Usually, it will just be emptying the tray, brushing the gird, and very occasionally replacing the UV light source.

Placement – Indoors or Outside

Also, it must be clear where you can place it. Some are for indoor use only, (although if you have a dry sheltered place outside perhaps it can be used there), others are designed to be placed outside and there are a few that can be used indoors or outdoors.

You should also be aware that a bug zapper shouldn’t be placed in an area where food is prepared. Electrocuted insects can be transformed into a sort of mist containing insect parts that can transmit bacteria.


Most zappers don’t use chemicals and are completely safe, but some do use attractants to entice insects into the grid. Make sure any chemicals used are safe for humans and animals.

Most bug zappers have built-in safety features to stop someone who touches the grid from being shocked, usually in the form of a protective grid. This is important if you have small children or pets, as the electrified wires can give a painful electric shock.

Power – Plug-In, Battery, or Solar Power

The power source is an important consideration, depending on where you want to use your device and whether there will be people in the area you use the zapper. Having extension leads on the terrace, in the garden, or even in the house can be an extra hazard. Battery or solar-powered models can provide an alternative.


Check the consumer reviews to understand any problems other users might have had and, in case of problems, whether the customer service was reactive.


This is another important point to consider, many zappers are reasonably priced at around $40 or less, and their running costs are very little – some electricity and perhaps an attractant to replace every few weeks for some of the outdoor bug zappers.

In comparison, a propane mosquito trap that works by emitting CO2 can be much more expensive to buy if you want to trap mosquitoes. Also, the ongoing costs of running a CO2 trap are more important.

This product is considered one of the most energy-efficient insect killers as it requires only 15 watts of electricity to function.

In addition, there is a cartridge of slow-release octenol attractant bait, which increases effectiveness against mosquitoes and other biting flies. Octenol is a component of human respiration. The lure is heated when the zapper is on and is vaporized.

The users of this Flowtron electric insect killer are mostly delighted with its performance. Of more than 13,000 reviews, over 80% are 4 or 5-star reviews. But while most find it works great, others see it as useless. You will still have to see for yourself if this insect zapper will kill annoying and biting bugs in your backyard.

Although the bug zapper does have a very short cord, like less than one foot, it is not a problem, as you will need an extension lead to position it at least 25 feet from where people gather.

Flowtron also manufactures two larger models if you have a bigger yard, the BK-40 for 1 acre and the BK-80 for 11/2 acres.
