Top 5 Best Bug Zapper Reviews

After much research and deliberation, I was finally able to narrow down the of 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.

Best Outdoor Bug Zappers

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.

It is suggested that you use the attractant as mosquitoes are not naturally attracted to UV light. This one is designed to be hung on a hook which can be purchased when you purchase it so you can stick it in the ground a safe distance from you and your activities.

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.

Types of Bug Zappers

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.

FAQs – Frequently Asked Questions About Bug Zappers

Q: Is it safe to use in the kitchen and around 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.

Q: Is it 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.

Q: What kind of bugs does it zap?
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.

Q: Do they make zappers that don’t make sounds every time an insect dies?
A: 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.

Q: 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

  • 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.


Bug zappers come in all shapes and sizes. With different voltages and even methods of attracting those unwanted pesky pests. In the end, to get what you want, you have to know what you want.

Whether you are grilling out in the backyard or you are leaving the doors and windows open on a cool summer night, you have one thing you don’t want to worry about. Insects. Now that you have a better understanding of what a bug zapper really is, you are ready to go out and start shopping for your own.

A good place to start is certainly the ones on my list and then you can go from there to finding the best bug zapper for your home and yard.
