How to Shop for Bug Zappers

The best way to control all kinds of unwanted flying insects around your home or business is by using electric bug killers, also know as “bug zappers”.

In this article we review and compare the best bug zappers on the market based on overall sales and customer ratings.

Mosquitoes and flies pose a particular inconvenience to homeowners. So the products we reviewed are best in the categories of electric mosquito killer and electric fly killer.

Electric-Kapas-Outdoor-Mosquitoes-Coverage-2 insect killer

In this side-by-side product review Outside Pursuits leads you through everything you need to know in order to compare and choose the best bug zapper for your specific needs and home environment.

These are reliable, effective bug killers that are able to control populations of several types of flying insects.

Before you venture out into the wonderful world of electric bug zappers, there are several things you need to consider first. I have made a list of four items to think about.

After much research and deliberation, I was finally able to narrow down the dozens to five. These 5 bug zappers are what I consider to be the best on the market.

Since we all have different bug zapping needs, there is a variety of shapes, styles, and purposes. I also made sure to include a few for indoor use and a few for outdoor use. Let’s get started with the outdoor zappers first.

I also want to explain why all bug zappers are not created equal and why the light is very important to attracting to pesky critters.

Outdoor bug zappers are what you would place on your patio, in the garden, and near the swimming pool to keep the insects away from you and your family.

They tend to be weather-proof and will not rust or become damaged if they get wet. I have a list of three that I consider worthy of being called the best bug zappers.

Types of Bug Zappers

We’ve divided the product reviews into the (2) sections: “Best Outdoor Bug Zappers” and “Best Indoor Bug Zappers” so that you’ll learn the right product for your specific property needs.

Beyond outdoor versus indoor there are four primary types of bug zappers: vertical, horizontal, light bulb and non-luminescent.

Vertical Zappers

Vertical Zappers are nice because they can be made waterproof. That means they can be left outside. Usually, they are structured with a non-metallic exterior to help prevent people and pets from being electrocuted.

This is the best design for outside use like near the pool or around the patio.

Horizontal Zappers

Horizontal zappers are usually found for interior use as they can’t really be made waterproof. They usually look like a metal box but instead of having every side closed, there is wire mesh on the front to allow the bugs to see the light and enter to their eternity.

Light Bulb Zappers

Light bulb zappers are what they say, a light bulb that you can screw into a normal light bulb socket. These are usually for external use like in an enclosed area where they won’t get rained on.

They do emit a small amount of light so they can be used to replace or used with other porch lights. And they will zap the insect attracted to it.

But it doesn’t have any wire mesh or non-metallic casing for catching the dead insects or protecting people and animals so it is best not to put it in reach of these things.

Non-luminescent Zappers

Non-luminescent zappers do not use a light source to attract insects. In fact, they use a high pitched sound that humans cannot hear to scare off the insects.

This means that they don’t actually zap or kill the insects, they just ward them off from the area surrounding the device.


Most bug zapper will have a light source. This is because insects are naturally drawn to light. For this reason, you will want to keep the bug zapper away from the location that you don’t want the bugs because they must be attracted before they are zapped.

Typically, there are three types of lights used in bug zappers. Neon and Ultra Violate or UV are very common. Though insects can actually see UV lights best, making it the most common option.

The third type is a mercury vapor lamp which essentially produces light by burning mercury. It is confined in a glass tube so it is not harmful to people. But it will attract and lap flying bugs, especially at night.

Wire Mesh

Wire mesh is how the bugs get zapped. One to two layers of wire mesh are formed around the light source. When the bugs fly toward the light, they meet the wire mesh first and that is when they get zapped.


Make sure when you buy your bug zapper, it has high voltage wire mesh for the best defense against those nasty insects trying to ruin our party.


Housing refers to the exterior design of the bug zapper. The biggest thing to consider with housing is safety. The better and safer zappers usually have a plastic or non-metallic exterior to help keep people and pets safe from electrocution.

The second thing to consider with housing is whether or not it is waterproof. If you want to use the zapper outside in the elements, it needs to be waterproof in case of sudden rainstorms.

Not all bug zappers are meant for outdoor use so make sure the model you purchase is if you want to use it outside


Most bug zappers emit some kind of sound. There is usually a humming sound when it is running. This is because of the electricity running through the wire mesh.

And usually, when a bug gets zapped, it makes a popping sound. There shouldn’t be any sparking but there is normally a sound.

When shopping for bug zappers, it is probably a good idea to look for one that is as quiet as possible.

Reading product reviews and things like that from customers who have already purchased it will give you a good idea of the noise level of the zapper while it is turned on and when it zaps a bug.

Bug Zapper FAQs

Do bug zappers really work?

Yes, the short answer is bug zappers do work. They use a special UV light and sometimes certain scents or chemicals that attract flying insects into an electrified grid. The bug flies in, completes the circuit, and is electrocuted resulting in instant killing of the bug.

Do bug zappers attract mosquitoes?

Some bug zappers do attract mosquitoes while others do not specifically attract mosquitoes. You can look for this with individual bug zappers that you are considering for purchase. Remember that even if they don’t specifically attract a certain flying insect, they will still likely eliminate some of them if they are in the area.

What bugs do bug zappers attract?

Different bug zappers are designed to attract different flying insects. Most bug zappers claim to attract a specific set of insects such as mosquitoes, flies, gnats, and other biting insects that fly. You can look at individual bug zappers to see what insects they are most effective against.

Do bug zappers make a difference?

Absolutely! There are thousands of consumers that agree that bug zappers have made a huge difference for them. A good bug zapper will successfully reduce the population of flying insects in any given area. In some cases, they can nearly eliminate it altogether. This works by killing off adults before they are able to successfully breed.

Is it safe to use in the kitchen and near food?

Here is an interesting fact, these bug zappers can actually splatters the insects’ remains up to 6 feet away from the initial zapping location.

In other words, it is not advisable to hang on above your dining room table. Ideally, you will keep it at a safe distance where the bugs will be attracted to the zapper and away from your family and food.

Are electric insect killers 110V or 220V?

This depends on the specific bug zapper. Some are suitable for both. But it is important to make sure they are suitable for the voltage you are using.

The standard in North America is 120v so the 110v is what you need. If you use 220v you will need a converter so you don’t short-circuit the zapper or blow a fuse.

What kind of bugs will a bug zapper kill?

Most bug zappers are effective against gnats and flies for sure. Though mosquitoes are not attracted to UV lights, if they are in your yard, they will most likely be zapped by your zapper.

Bees, wasps, yellow jackets, hornets, and horseflies are also usually attracted to the light source.

Other insects like moths, and even ants, and centipedes that don’t fly are attracted to the light and will be zapped. You can also add things like specific insect pheromones to attract them to the light.

Do they make bug zappers that don’t make sounds every time an insect dies?

Not really, not unless you are using something to repel the bugs instead of zap them. The zapping sound is caused by the electrical current jumping from the wire mesh to the insect which is what kills the insect.

Kind of like when you wear socks and walk across the carpet and touch a metal doorknob. But some are significantly quieter than others. If the sound bothers you, try keeping further away from the area you are most of the time.

It will still attract the insects, even if it is farther away from you.

What is the range that the bug zapper reaches?

Different bug zappers have different ranges. Most range from 500 square feet to 1 full acre. There are some that will cover even bigger spaces, closer to 2 acres. But for indoor, 500 square feet is most common. And 1 acre is most common for outdoor zappers.

Bug Zapper – Safety Tips

  • Keep bug zappers at a safe distance from food, children, and pets to avoid potential contamination and/or injury.
  • Make sure to keep the tray clean. The tray that collects the bugs after they get zapped will need to be cleaned. The frequency depends on the time of year and how big of a pest problem you have. Summer will naturally need to be cleaned more often than winter. If you are constantly using the bug zapper, it is probably a good idea to check it once or twice a week unless you see that it doesn’t need it that often.
  • ALWAYS unplug the bug zapper before you clean it. You want the bugs to get zapped, not you.
  • Make sure it is mounted properly. Some zappers can sit on the table and be fine while others are designed to be hung from a chain or mounted on a wall. Make sure you get the appropriate design for your situation.
  • Don’t use an indoor bug zapper outside and vise versa. This may seem obvious but it is something that is important to remember. Indoor bug zappers aren’t able to withstand the elements.
  • Follow all instructions for usage and cleaning. To avoid injuries and fire hazards, read the instructions before using and cleaning the bug zapper. It’s for the safety of you and your family.
