Selecting the best ultrasonic pest repeller is no simple task. The Federal Trade Commission already sent out warning letters to 60 lower quality brands, demanding additional proof of the quality of their products.
So my team and I decided to do some more research to see which products work. In this article, I’ve compiled a list of my top 5 recommendations. I’ll also answer some of the most common questions people have about pest repellers.
Top 5 Electronic Pest Control Devices
If you’re looking for total home protection against insects and rodents for a reasonable price, I recommend Home Sentinel. It’s one of the best ultrasonic pest repellers on the market today.
In addition to using ultrasonic sound frequencies and electromagnetic waves to displace pests out of your home, it also includes a third type of technology that’s not found in many other repeller products, called ionization.
A single unit covers up to 1,200 sf, and you can add more devices to your home if you’d like.
Keep in mind that the electromagnetic feature is one of the only repellents that can travel through the walls (via the wiring) to minimize pests. The size of the room bounds the ultrasonic sound and ionizers that the device is placed in.
If you have multiple floors in your house, this is a good option because it comes in a four-pack.
- Non-toxic and safe for kids
- Effective for indoor areas up to 1200sq.ft
- Simple electronic plug
- Technical support and customer service
If your house has a simple wiring system with most rooms being on one or two circuits, then this device could potentially save you some money. This is my second best pick.
It works strictly by sending electromagnetic pulses through your wiring to scare away rats and mice, among other common household pests.
What makes it a good pest device 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 sf).
This pest repeller also offers the convenience of a nightlight.
- EPA registered
- Built-in surge protector
- Sends electrical impulses through home wiring
- Effective for 1 level of the average size home
Second on the list of the best ultrasonic repellers is this product. What you’ll get with the MaxMoxie ultrasonic pest repeller is a two-pack for the same price as one.
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. This product was mentioned as being most useful as a mouse repellent.
- Manufacturer 30-day satisfaction guarantee
- Low input voltage power supply
- Easy to use pest reject functions
- 1200 square ft coverage area
This 4-pack of ultrasonic pest repellers is just the ticket to force those nasty critters 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 an ample open space like a basement, you may need to use two devices to cover the entire area.
These repellents also include a nightlight feature that can be turned on or off at your convenience. Some people mentioned it as being one of the top fly repellers.
- Four pack of ultrasonic repellers
- Various sound system frequencies
- Multispecies insect repellent
- Electronic chip for ultrasound waves
My last recommendation for the best ultrasonic pest repellers is this brand right here.
For just a couple dollars more than my #4 pick, you can get a total of 6 ultrasonic pest units to place around your home.
This is a reasonably good deal, and that could potentially protect your home from pest infestations.
If you don’t want to take any risk with cockroaches, ants, spiders, mosquitoes, mice, and rats invading your home, then this package should have you covered.
The only feature this ultrasonic pest repeller lacks is a nightlight.
- Affordable option
- Blue light for on/off notification
- Microchip system
- Pest reject ultrasonic repeller
Features to Look for in an Ultrasonic Repeller Device
Not all 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.
Let’s take a look at these key features below so you can ensure that you’re getting the right product for your needs.
Ultrasonic Waves and Sounds
Most pests have a strong reaction to ultrasonic waves and sounds. These sound waves 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.
The best ultrasonic pest repeller devices use sound frequencies as an invisible forcefield around your home, and the bugs and rodents that are inside are forced out, and the ones outside don’t want to come anywhere near it.
Individual Unit Coverage
Every electronic ultrasonic pest repeller has a limit on how much area it can cover. When you’re comparing pest control products, you’ll find that some repellers cover a small space like 200 sf while others can handle an ample space of 1,600 sq ft or more.
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 functions in my reviews above.
Number of Units Included
Some ultrasonic pest repeller brands only sell individual units while others come as a package set.
The number of units included with your purchase is significant because you may need more than one device to get rid of bugs and rodents in your home effectively.
As you learned 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 1200 sq ft, but if the room you use it in is only 600 sq ft, then that’s all the protection you’re going to get with one pest control device.
On the other hand, if you buy an electromagnetic device, you’ll get the full 1200 sq ft 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 sq ft with seven separate rooms, and you buy one ultrasonic pest repeller that claims to cover 1200 sf, 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 repellents that cover a large 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 ultrasonic pest repeller units include is an LED light. A night light 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.
A warranty offered by the manufacturer is another way to be assured that the product you bought is not a waste of money. This is for additional assurance while having the chance for a replacement or refund within the warranty period. Other manufacturers even offer a lifetime guarantee.
6 Advantages of Ultrasonic Pest Repellers
- Safety: A ultrasonic pest repeller 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 unit into a power source or power outlet, and it will start working immediately.
- Versatile: Ultrasonic pest repeller 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 repeller devices 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: Ultrasonic pest repellers work 24 hours a day for 1-3 years on end without needing to be replaced. What about its costs to power bills? There is no study to explain its effect on our electricity bill.
- They repel not kill: Using chemical sprays and baits to kill pests around the home can be inconvenient. Having to get rid of dead insects and rodents from your home is not something anyone likes to do. Additionally, if a bug or rodent goes off and dies, you can’t see after ingesting poison, an odor can start to emanate from the location which makes things much worse.
Get the Most out of Your Ultrasonic Pest Repeller:
- Follow the manufacturer’s instructions carefully when using your ultrasonic repeller. 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.
- Make sure to use the right number of repellers for each room. Every ultrasonic pest repeller and pest control device has a limited range it can cover. Therefore, read the manufacturer’s 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 cover the intended space fully.
- Be patient. Pest elimination takes time, especially if you have a severe mouse problem. 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.
Frequently Asked Questions
How to Use an Ultrasonic Pest Repeller?
All you have to do is plug an ultrasonic pest repeller 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 ultrasonic pest repeller that sends vibrations through the wiring system of your home, there’s nothing more you have to do after turning the unit on.
What Types of Pests Do Ultrasonic Repellers Get Rid Of?
Most ultrasonic pest repellers are advertised to get rid of ants, roaches, mice, rats, squirrels, snakes, mosquitos, flies, and fleas. But please note according to the Entomological Society of America, bed bugs are not repelled by ultrasonic devices. 
Is an Ultrasonic Pest Repeller Safe Around Pets?
Yes, ultrasonic pest repeller devices are safe to be around pets. It appears that cats, dogs, and birds are unaffected by these sound waves. Some smaller animals like hamsters or rabbits may react 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 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 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 of a pest problem 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 repeller products.
How Much Area Does One a Unit of Repeller Cover?
Manufacturer’s claim that one unit of repellent can cover an average of 400 up to 1,200 sq ft (this depends on the unit). It is usually suggested to place in multiple rooms, depending on how big your house is.
Where Should I Place the Repeller?
It is recommended to place the repeller in the part of a room where there are abundant signs of pest activity. This is usually the kitchen where rodents sniff around foods or left-overs.
Though it’s hard to look for signs of rodent activity because they creep around at night only, my suggestion is to look for other signs of pest infestation. For example, gnaw marks, chewing, tracks, nests, droppings, and even their strong urine smell.
Another essential thing I suggest is to plug the unit in an open space. Not behind a piece of furniture where the sound waves are blocked. This is the common mistake of people claiming that ultrasonic pest repellers don’t work. So it is always important to strategically place the repeller to witness optimal results.
What Is the Lifespan of a Rodent Infestation Inside My House?
They can live up to two to three years inside your home though it can only live up to less than one year when outdoors or the back yard. In addition, it gets pregnant up to five to ten times each year and produces 3-14 pinkies (baby mouse). Imagine the mice problem and disaster this can result in.
What Are the Other Types of Pest Control Methods?
- Organic Pest Control – This is with the use of insecticidal sprays, poisoned bait, or mouse traps.
- Chemical Pest Control – These are chemicals that can be used for residential and commercial purposes. These are in the form of aerosol, solid, and liquid. Remember to use this with precaution because of its harmful effects on humans.
- Biological Pest Control – Using another living organism to control the pests.
- Pest Control Services – By pest control companies.
And the #1 Ultrasonic Pest Repeller Is …
Based on the countless hours of research and reading numerous product reviews, I recommend the Home Sentinel pest controller. It offers an ultrasonic frequency of 50-60Hz and comes conveniently in a 4 pack. This is a good option if you’re trying to cover multiple floors in your home.
It’s safe for pets and humans and is shown to be effective in getting rid of most critters, including mice, cockroaches, and spiders. If this sounds like something you’re interested in, click the link to check the current price.
