How to pick the best electronic pest repeller device

Are you sick and tired of insects or rodents invading your home?

Do you want to get rid of these annoying pests without spending a ton of money on an exterminator?

Fortunately, you can now get rid of these pesky buggers without much effort by using inexpensive electronic pest repellers and I’ll show you how in this free guide.

Indoor electronic pest control devices are safer alternatives to chemical pest control that anyone can set up and use. All that’s required is to take it out of the package and plug it into an electrical outlet.

Then, you just sit back and wait while all those creatures are driven out of your home.

Ultrasonic sounds and electromagnetic waves repel insects and rodents

You see, most pests have a strong reaction to ultrasonic sounds and electromagnetic waves. These sounds and vibrations, which are inaudible to humans, drive insects and rodents nuts. They can’t stand being around that type of environment and they’ll do anything to get away.

Basically, the best electronic pest control devices create an invisible forcefield around your home and the bugs and rodents that are inside it scramble out, and the ones outside don’t want to come anywhere near it.

But, how do you find the best electronic pest repeller without testing dozens of products or reading through massive amounts of reviews?

Here’s where I can help!

As your trusty companion, I’ve researched and compared more than 16 electromagnetic and ultrasonic pest control devices and know which ones actually force those unwanted invaders out of your house.

In this free guide, I’ll show you how to pick the best device for your needs as well as show you what the top features are to look for. I’ll also answer some of the most common questions people have about these pest repellers.

By the end, you’ll have all of the knowledge necessary to pick the right device.


Trusty Joe with Checklist

Features to look for in the best electronic pest control devices

Not all home pest repellents work the same way. If you buy the wrong type, it won’t get the job done and you’ll end up wasting your money.

Before we get into my electronic pest control reviews, take a look at these key features below so you can ensure that you’re getting the best product for your needs.


Electromagnetic waves

Electronic pest control devices come in two types. The first type uses electromagnetic waves to get rid of insects and rodents from your home.

Once you plug this type of device into a power outlet, it starts sending electric pulses through your home’s wiring system. These vibrations go straight to the source of where insects and rodents live: behind your walls.

This technology disrupts the places pests like to reside so much that they have no other choice but to leave.

The most important thing to remember here is that electromagnetic devices are the only type of product that can penetrate through walls. And your home’s wiring system will determine how many devices you actually need.

  • Older homes tend to have multiple rooms on the same circuit, so plugging one device into an outlet can essentially protect several rooms at once.
  • Modern homes, however, have one or two circuits per room. This new electrical design helps keep your circuit breaker from overloading and causing a fire. With this setup, it may be necessary to use one pest control device per room to cover your entire house.

How many electronic pest repellers do you need?

To get a better idea of how many of these devices you’ll need in your home, go to your circuit breaker box and take note of how each breaker is labeled. For example, if one switch says “Living Room/Bedroom” then you know that plugging an electromagnetic repeller into one of the outlets in either room will protect both rooms at the same time.

If one breaker switch says “Basement 1” and another “Basement 2” then the wiring is split in that room and you’ll need two devices plugged in to cover it.

sound waves

Ultrasonic sound

The second type of pest control device uses ultrasonic sound to eliminate pests.

When you plug one of these repellents into a power outlet, it emits a high-frequency sound that pests can’t handle. This sound confuses bugs and rodents an eventually drives them out of your home because they can’t communicate, breed, or hunt for food effectively.

Can you hear these ultrasonic sounds?

Ultrasonic pest controllers are inaudible to humans, and household pets such as dogs, cats, ferrets, birds, etc. So, you don’t need to worry about anyone being affected by the sounds they produce inside your home.

How many ultrasonic pest repellers do I need?

The one thing to remember about this type of pest repeller is that it can’t penetrate through doors or walls. Ultrasonic devices can only stop pests within the four walls of the room that they’re placed in. This means you’ll need to put one device in each room of your home that’s enclosed in order to get total coverage.

To make things easy for you, I’ve reviewed the best ultrasonic pest control device from just a single unit up to a package of six below.


Individual unit coverage

Every ultrasonic or electronic pest control device has a limit on how much area it can cover.

When you’re comparing products, you’ll find that some repellers cover a small space like 200 square feet while others can handle a large space of 1,600 square feet or more.

Obviously, the more area a device can cover, the better value it will be for your home. I’ve listed the specifications for each of the best electronic pest repeller models in my reviews below.


Number of units included

Some pest repeller brands only sell individual units while others come as a package set.

The number of units included with your purchase is important because you may need more than one device to effectively get rid of bugs and rodents in your home.

As you learned in the section above about ultrasonic pest repellers, these devices are limited to the size of the room they’re placed in. A product may advertise that it can cover 1,200 square feet, but if the room you use it in is only 600 square feet, then that’s all the protection you’re going to get with one device.

On the other hand, if you buy an electromagnetic device, you’ll get the full 1,200 square feet of coverage because this technology works behind the walls through your wiring system and is not bound by physical barriers.

Keep this concept in mind when you’re shopping for pest repellers so you know how many to get.

  • For example, if the main level of your home is 1,000 square feet with 7 separate rooms, and you buy one ultrasonic pest controller that claims to cover 1,200 square feet, it’s not going to cover the whole floor when placing it inside one of those rooms. The walls will block its full radius.

In that example, you’ll need to put one unit in every room that’s surrounded by four walls.

In my reviews below, you’ll find recommendations for the best cheap indoor electronic repellents that cover the largest amount of space. To make it easier for you to make a decision, I’ve included the square footage ratings for two single units, one 2-pack, one 4-pack, and one 6-pack.



An optional feature many home pest control devices include is a nightlight.

A nightlight serves a dual purpose.

  • The first purpose is to light up your hallways or rooms to help you see better at night.
  • The second purpose is to act as an additional repellent for certain pests. Some insects don’t like light, and so they’ll avoid areas that are lit up.


The Top 5 Electronic Pest Control Reviews

During my research, I uncovered a lot of good (and bad) products when putting together this list of electronic pest control reviews.

What I discovered is that not all pest repellers work as advertised, but some definitely do. After comparing the best products⁠—and eliminating the junk⁠—I was finally able to narrow down the top five winners for you.

What you’ll find below is an assortment of options for every person’s needs. There’s an individual electromagnetic device, several ultrasonic repellers, and a combination device that includes both repellent technologies.

Review Top Choice

Home Sentinel Full Electronic Pest Control

Review Home Sentinel
If you’re looking for total home protection against insects and rodents for the lowest price, this is the best electronic pest repeller to get.

In addition to using ultrasonic sound and electromagnetic waves to drive pests out of your home, it also includes a third type of technology that’s not found it many other repellant products, called ionization.

The ionizer emits charged particles into the air to create the feeling of an incoming storm. This invisible field pushes bugs and rodents out or your house to seek shelter elsewhere. (Ionization is completely safe for humans.)

A single unit covers up to 1,200 square feet and you add more devices to your home if you’d like.

Keep in mind that the electromagnetic feature is the only repellent that can travel through the walls (via the wiring) to eradicate pests. The ultrasonic sound and ionizer are bound by the size of the room that the device is placed in.

If you have multiple floors in your house, you should consider buying at least two of these devices. That way you can get the maximum protection against insects and rodents.


Review Second Best

Pest Defense Electronic Pest Repeller

Review Pest Defense
If your house has a simple wiring system with most rooms being on one or two circuits, then this device could save you a lot of money.

It works strictly by sending electromagnetic pulses through your wiring to scare away mice, rats, roaches, spiders, ants and other common household pests.

What makes it one of the best electronic pest control devices is that it can cover a very large area and is not limited by walls or other objects.

One unit has enough power to protect an entire floor of an average size home (1,200 to 1,600 square feet).

This pest repeller also offers the convenience of a nightlight.


Review Third Pick

MaxMoxie (2-pack) Ultrasonic Pest Control Device

Best Ultrasonic Pest Control Device Pack by MaxMoxie
If you want to give a cheap ultrasonic pest repeller a try but don’t want to spend a lot of cash, this 2-pack is a great investment

Essentially, what you’re getting are two electronic repellents for the price of one.

If you’re not sure how your house is wired and don’t want to take a chance buying my #2 pick, this cheap ultrasonic pest control package could be just what you need.

Each unit covers 1,200 square feet of space or 2,400 total.

A good way to test the waters with a package like this is to place one device in a central location like a living room and keep the doors open in adjacent rooms. With fewer obstructions, the ultrasonic sound waves may be able to reach these other areas of your house from this single unit.

Then you can place the second device in a nearby hallway to help broaden the protected space.


Review Fourth Pick

Ultrasonic Pest Control Devices (4-pack)

Review Ultrasonic 4 Pack
Do you have problems with bugs or rodents in multiple rooms of your house and want to get rid of them as fast?

If so, then this 4-pack of ultrasonic pest repellers is just the ticket to force those nasty buggers out of your home for good!

Each unit covers 1,500 square feet (6,000 in total) which is plenty enough power to protect four medium to large size rooms.

For a large open space like a basement, you may need to use two devices in order to cover the entire area.

These electronic pest repellents also include a nightlight feature that can be turned on or off at your convenience.


Review Fifth Pick

Ultrasonic Pest Control Devices (6-pack)

Review Pest Reject
My last recommendation for the best ultrasonic pest control device is this brand right here.

For just a few dollars more than my #4 pick, you can get a total of 6 ultrasonic control units to place around your home.

This is an amazing deal and offers you maximum home protection.

If you don’t want to take any risk with cockroaches, ants, spiders, mosquitoes, mice or rats invading your home, then this package has you covered.

The only feature these devices lack is a nightlight, but if you’re going to have 6 of them around your house, you probably don’t want every room of your home lit up by them anyway.

If this sounds like what you’re looking for, give them a try!

How to use an ultrasonic and electronic pest repeller?

Ultrasonic and electronic pest repellents are very easy to use. All you have to do is plug these devices into an electrical outlet and they’ll immediately start working.

Some repellers do include a switch to turn the unit on or off, so be sure to look for this function after unboxing it.

  • If you’re buying an electronic pest control device that sends vibrations through the wiring system of your home, there’s nothing more you have to do after turning the unit on.
  • If you’re buying an ultrasonic pest control device, then you’ll want to make sure that it’s placed in a location where the high frequencies it emits will not be blocked by furniture or other large solid objects. Placing the repeller in an open facing area will allow the sound waves to travel the furthest inside a room.

Why should you use an electronic pest control device?

There are several advantages to using an electronic pest repeller or ultrasonic pest control device over traditional chemicals and bait. These include:

  • Safety: Electronic pest control doesn’t use chemicals or poisons to eradicate bugs and rodents. This means these products are safe for humans and pets to be around without fear of ingesting or inhaling toxic materials.
  • Ease of operation: No expertise is required to get started. Just plug the device into an electrical outlet and it will start working immediately.
  • Versatile: Ultrasonic and electronic pest control devices ward off a variety of household pests including bugs and rodents. You don’t have to perform a separate exterminating process to get rid of each type.
  • Use anywhere: Since ultrasonic pest control devices and electronic repellers don’t use harsh chemicals, they can be used in any room of the home without any worry. This includes children’s rooms, pet areas, basements, and more.
  • Long-lasting: Chemical repellents wear off over time and must be reapplied in order to stay effective. Electronic pest repellers work 24 hours a day for years on end without needing to be replaced.

The good news: these devices repel and don’t kill

Using chemical sprays and baits to kill pests around the home can be a very icky task. Having to remove dead insects and rodents from your home is not something anyone likes to do.

Additionally, if a bug or rodent goes off and dies in an area you can’t see after ingesting poison, an odor can start to emanate from the location which makes things much worse.

With electronic and ultrasonic pest repellers, you don’t have to worry about picking up dead insects or rodents because these devices repel and don’t kill. The ultrasonic waves and electronic pulses push these critters outside of your home and force them to go somewhere else. Therefore, you won’t have to worry about them dying inside your home or leaving and odor.

What types of pests do ultrasonic and electronic repellers deter?

Here is a list of the types of insects and rodents these devices can help deter from invading your home:

  • Ants
  • Roaches
  • Mice
  • Rats
  • Squirrels
  • Snakes
  • Mosquitos
  • Flies
  • Fleas

Note: According to the Entomological Society of America, bed bugs are not repelled by ultrasonic devices.

Are electronic and ultrasonic pest control devices safe to use around pets?

If you’re a pet owner, it’s natural for you to wonder if ultrasonic and electronic pest control devices are safe to be around pets. Since these devices emit high-frequency sounds and pulses it may be a reason for concern.

Fortunately, studies have shown that cats, dogs, and birds are unaffected by these sound waves. Some smaller animals like hamsters or rabbits may have a reaction to these devices because of their hearing abilities, so keep that in mind if you do have these pets at home. You may not want to use a pest repeller inside the room that houses the cages of those types of animals.

Are ultrasonic and electronic pest repellers effective?

It may be hard to believe that you can just plug a device into your wall outlet and magically it repels insects and rodents.

However, many ultrasonic pest repellers and electronic pest control devices do live up to their claims.

Like with any product, not everyone will experience the same level of success using it, but, these devices are worth a shot no matter where you live or how bad an infestation you may have.

Just remember that pest repellers are not designed to kill bugs and rodents, but rather repel them from your home. This process can take some time to work effectively and it doesn’t always happen overnight. Additionally, some pests are brave souls and will invade your house no matter what you use. This is even true when using chemical pest control products.

To get the most out of your electronic and ultrasonic pest control devices follow these simple tips:

  • Follow the manufacturer’s instructions closely. Each product comes with its own set of guidelines and requirements to work effectively such as a recommended distance from the floor, avoiding the placement behind curtains, the best location inside a room, etc.
  • Use the right number of repellers for each room. Every ultrasonic pest repeller and electronic pest control device has a limited range it can cover. Therefore, read the manufacturers instructions to find out how far it can reach. Then, place the unit in a room that is less than this number or invest in multiple units to fully cover the intended space.
  • Be patient. Pest elimination takes time. If you find that ants, spiders, mice or other pests are still invading your home, just wait a few days before you box the unit up and make a return. It’s normal for these critters to make their presence more known after installing an electronic or ultrasonic pest repeller because they’re usually trying to find their way out of your home. Let the unit do its job before you panic and call in an exterminator.
