The world’s improving technologies can be seen in all kinds of products, and one important example of it comes in pest control.

Many people have problems with squirrels, or other rodents and pests in or around their homes, but might be morally or emotionally adverse to killing any animal or living thing. 

Luckily, thanks to these technologies and advanced animal research, alternatives to setting traps and killing animals are available.

For people who have a particular problems with squirrels, this article will focus on the best ultrasonic repeller for squirrels that will help you control your problem in a safe, human, and effective way.

First, the article will look at some of the problems that squirrels can cause in and around your home.

The next section will briefly explain the technology surrounding ultrasonic repellers.

Finally, the article will look at three products that we think are all candidates for the best ultrasonic repeller for squirrels.

Squirrel problems

While they can be cute creatures, squirrels and other rodents present a few kinds of annoyances and hazards for homes and apartments.

If you have just moved into a home either in the country or in an urban area with lots of critters, you might be interested in what pest prevention might entail for creatures like these.

Chewing wires

If there are wires around, who needs an acorn?

Squirrels have the potential to chew on wires, either in your home if they are able to get inside and in the walls, or underneath a vehicle if they can get into your garage or barn.

This is not only dangerous for the animals, but can be dangerous for you or your home as well.

Disease and cleanliness

Having small rodents in or near the home is particularly unsafe if you have small children or other animals.

Diseases be spread through their droppings or on their fur, especially if they are nesting or hanging out in your attic.

It’s also just not that pleasant to be stepping into rodent droppings every time you walk out onto your front porch, or if one of them gets trapped in your home somewhere and dies.


Squirrels are foraging creatures, and your garden or trees are no except to what might draw them.

If you want to keep them away from these plants, consider getting a battery-powered, weatherproof repeller like the Izbie Z1 listed below.

How an ultrasonic repeller works

Squirrels can be an important part of the larger ecosystem, so killing them is not always the best way to solve a problem.

That’s where ultrasonic repellers come in. 

Ultrasonic repellers work by emitting sounds at frequencies outside of the range of human hearing that drive the creature away.

It’s something like a dog whistle (and actually, many ultrasonic repellers drive dogs away as well), though to the creature it is more like constantly hearing the sound of a dentist’s drill.

We would walk away also!

Some repellers offer multiple sound options; some of these might be audible to humans.

This just gives another option to repel creatures, especially if the machines will be running regularly.

Many manufacturers recommend switching to an audible mode when humans are not home, so it’s not distracting to humans.

This variation will also help ensure that creatures do not get bored or used to the noise, which does not happen much but is a small possibility (especially if your batteries are running low and the device operates without being at full volume).

Ultrasonic repellers also generally include lights that aid in pest deterrent.

Small creatures are sensitive to certain lights, and because they might perceive it as danger, are also deterred by the flashing buttons.

What to look for (and avoid) in an ultrasonic repeller for squirrels

There are a few things to consider when looking for ultrasonic repellers for squirrels.

Depending on your situation, you will want to take these into consideration as you plan the best way to set up the repellers in and around your home or property.

Outdoor versus indoor

Ultrasonic repellers are designed to work either indoors or outdoors.

Outdoor repellers will be water and weatherproof, generally, so rain and snow will not deter them.

You will just have to make sure the batteries are charged regularly so that the device does not stop function when you least expect it.

Repellers can also be placed inside rooms and vehicles, and many are generally small enough to be able to do so discretely.

Remember that repellers contain flashing lights as well, so you will want to position it away from visible places if you will be using the room at night.

Power supply

Ultrasonic repellers generally receive power from plugging them into the wall.

Some models are battery powered, so you will have to purchase batteries separately, but can free up an outlet in your home.

If the battery-powered repeller is waterproof, it can also be used outside.

Some repellers, including two on this list, include rechargeable batteries that can be charged using the wall outlet that comes with the product.

Charging the batteries with a solar panel is also a feature of some of the products on our list.

This is especially great for devices that are placed in gardens or on patios, and will help you lower your electric bills in the summer.

The important thing for any battery-powered repeller is to make sure that the batteries do not lose power.

If they do, squirrels and other creatures will not have any reason to stay back anymore.

Keeping your repellers running is imperative for seamless, seasonal protection, which requires patience and upkeep on your part but at no risk to the creature, the ecosystem, and most importantly, your home and family.

Coverage area

While most repellers can cover a single room with no problem, pay attention to the coverage area listed in the product description.

Many products note that rooms with carpeting can absorb the sound, and that thick walls in between rooms can dampen the effect of the repeller as well.

In general, if your squirrel problem is severe, having several repellers for different rooms strategically spread in areas that the creatures hang out is a good solution rather than looking for the repeller that provides the widest range of coverage.

Best ultrasonic repeller for squirrels

There are a number of repeller options that may work well for use on a squirrel problem around your home.

It’s important to always consult an industry professional before using any new product.

The following options may work well for getting started with your search.

Ultrasonic Pest Repeller by Wide World – Solar Powered Waterproof Outdoor Wild Animal Repellent – Motion Sensor and Flashing Light for Deer Cat Dog Squirrel Mole Rat Fox Wolf Raccoon – Sound Control’

This product emits slightly lower ultrasonic waves than the other products on this list, making it an ideal product to use if you have pets that you don’t want to be bothered by the sound.

It features a waterproof design and rechargeable batteries, so it can be used in outdoor spaces like patios and gardens.

Like the Izbie Z1 below, there is also a solar power recharging option, which is great for sunny days and for cutting down on energy usage.

This repeller is similar to the Izbie Z1, but has a smaller range.

We recommend using this one in smaller areas closer to the home, or in spaces that has a bit of protection from the rain or snow.

At the same time, it is highly powerful within the home.

The batteries are rechargeable through solar power, allowing you to cut down on electric bills while keeping your home squirrel free, as well as a wall adapter for cloudy days.

These devices have a range of up to 30 feet, though it is generally recommended to keep one in every affected room if you have a larger problem.

Like all ultrasonic adapters, these devices will not hurt the animal. For this product, make sure you utilize the recommended settings to ensure maximum protection.

Advanced Ultrasonic Rodent Repelling System | Superior Rodent Repeller, 2020 Upgraded Electronic Ultrasonic Squirrel Repellent Plug in, Rat Repeller, Repel Rodents, Mice, Rats, Squirrels

This great device offers two ultrasonic modes to increase the effects of repelling squirrels and other small creatures.

It is geared for indoor use, which might be limiting to some users, but comes with an adapter and can be plugged directly in the wall in the room you wish to keep it.

It features a large coverage area, though like most ultrasonic repellers it is recommended to keep one in every affected room to ensure that your walls do not block its emissions.

Note that one of the modes is audible to the human ear, so it is ideal to use this when the home or room is empty.

Also, make sure that you keep it off of the carpet so the sound is not absorbed.

If your home is fully carpeted, think about getting a small table or stool so the emissions can reach nearby squirrels.
