When mice attack your home, it’s normal to want them out as soon as possible. Unfortunately, they won’t leave voluntarily.

There are several actions you can take to make your home unwelcoming to these critters. If you’re a healthy minded individual who doesn’t want to risk exposing your family to toxins or are looking for a humane way to eliminate mice, you probably won’t find traditional pest control methods to be appealing.

Thanks to the advancement of pest removal technology, there’s a way to get rid of mice without trapping or poisoning them – with the sound emitted by an electronic mouse deterrent. So how do you use it? Does it even work? Let’s dive deeper and find out more.

How Do You Keep Mice Away With Sound?

Besides their highly developed sense of smell, mice possess an acute sense of hearing. Humans can hear some of the sounds that mice can hear. However, much of the hearing range of these rodents is above that of humans.

A device that can generate sounds that only mice hear can be incredibly intrusive to these rodents, helping drive them away from a certain area.

What Sound Frequency Repels Mice?

Ultrasound, which is sound that’s higher than 20 kHz, will act as an irritant when applied to mice. While it’s not possible for humans to perceive this sound due to the cochlea’s physical limitations, mice will clearly hear them without perceiving the source of the unsettling noise.

Sound sensitivity in different animals (from Dusenbery, 1992)

Animals sound sensitivity

To mice, this sound is like having a smoke alarm that keeps going off or a next-door neighbor that has a jackhammer running constantly. It subjects them to profound auditory stress.

Mice also don’t like the sound of a dominant male mouse. That’s because they’re territorial animals and will constantly fight for dominance. Therefore, a sound that replicates that of a dominant mouse will discourage these rodents from occupying a particular territory.

To remove mice from homes and prevent them from ever coming back, some homeowners plug up cracks and holes with steel wool. But is this effective? Go here to learn more about using steel wool for mice.

Sound App

There are several mobile apps that claim to scare mice away. Some do this by releasing ultrasound whereas others mimic the sounds made by some of the well-known enemies of mice.

Some of these apps have received numerous positive reviews whereas others have many negative reviews. Based on customer feedback, it’s safe to say that some apps live up to their claims while others don’t.

Let’s look at some of the mouse deterrent apps that are available for download:

  • Rat and Mouse Sound Repeller

Ultrasonic Mouse Deterrents

Ultrasonic mouse deterrents are devices that emit noise at ultrasonic or very high frequencies, which are beyond the range of human hearing. The sounds discourage mice from feeding or settling in the affected areas.

Ultrasonic mouse deterrents don’t affect electronics like TVs and computers.

These devices offer several benefits.

They include:

  • Eco-friendly. They don’t have any chemicals that may pollute the environment or harm your family.
  • Versatility. Apart from mice, ultrasonic devices can repel many other pests including squirrels, raccoons, spiders, cockroaches, ants, and fleas.
  • Large area. One unit can cover a large area (2,000-6,000 square feet), helping lower costs.
  • User-friendliness. Once powered up, they don’t have to be monitored.

Plug In Mice Deterrents

While some electronic mice repellents are battery powered, most have to be plugged into an electrical outlet hence the name plug in deterrents. The electricity generates high-frequency sound that the rodents don’t like. To avoid the irritation, they’re forced to depart the area.

Some people have found these repellers to be highly useful. Others have found them to do little in solving their rodent problem. It’s important to note that even the best repeller will only work if it’s applied properly. There’s a high probability that most of the people that weren’t impressed by the devices were using them wrongly.

To boost your chances of achieving the desired results with a plug-in mouse deterrent, be sure to take these three factors into consideration:

  1. Location. You should first identify a room that has signs of mouse activity such as droppings and gnaw marks. Plug the ultrasonic unit into a power outlet that’s near the entry points of the pests and is in an open area. It shouldn’t be behind solid objects such as furniture that can block the sound waves.
  2. Number of units. Ultrasonic frequencies don’t penetrate solid surfaces such as walls, ceilings, and floors. For that reason, it’s best to use one device in each room. If a room has many obstructions, you can use more than one device.
  3. Check recent mouse activity. Regularly inspecting your rooms for mouse activity will allow you to verify that the pest population is reducing. Mice can cope with unfavorable changes for a short while, so don’t expect to see results immediately. On average, you should see reduced mouse activity after 6-10 days.

Let’s take a look at a few plug in mice deterrents:

The Most Effective

The ultrasonic device you purchase can be a hit or miss. You should perform due diligence on the different products to avoid wasting your hard-earned money.

One of the factors you should consider is how the devices project the ultrasonic sounds. Mice can get accustomed to the sound that an ultrasonic repeller produces, making results only temporary. Look for a device that produces varying sounds or sound patterns, preventing the rodents from easily getting used to them.

It’s also a good idea to consider the number of positive reviews from customers as well as the independent experiments conducted on the product.

Let’s help you out by listing some of the most effective ultrasonic pest control devices on the market:

The range of hearing in a cat or dog is wider than that of humans but isn’t close to the frequency with which rodents can be affected. As a result, most ultrasonic mouse deterrents don’t impact these pets.
However, the sound from these devices can affect guinea pigs, hamsters, rabbits, and other rodents. So make sure you relocate any domesticated rodents to rooms without repeller units.

Electronic Mice Killers

An electronic mice killer is swift, immediately killing the critters without any undue suffering. When a mouse steps onto the device’s kill chamber, electric currents shock and kill it.

These devices have a high kill rate. They almost always perform a complete kill.

What’s more, they offer several other advantages, which include:

  • No bloody mess to clean up.
  • Easy and safe to operate.
  • Can kill many mice per charge.

Let’s look at some electronic mice killers you can purchase:

  • Agri Zap Rat Zapper Classic Ii
    The device kills the mice and rats that enter into it with a quick jolt of electricity. A red light indicates when there’s a catch.
    Cost: $49.99
    Where to buy: on Amazon

Considering they’re clean, low maintenance and fairly inexpensive, electronic mouse deterrents are an interesting alternative to other types of rodent control. No matter how good the deterrent you purchase is, you’ll need to use it correctly and give it time to work to get your desired results. Don’t use set it up and expect overnight results.

For best results, you can use the devices in conjunction with traps. The sound waves will make the unwelcome guests scurry out from their hiding spots and get right into your traps.

  1. Very useful information. Is there an IPhone app that can be used to detect sound from electronic repellers to ensure the repellers are working properly?

  2. How long do these items last? Need to know if you have to buy them every so many years.

  3. Great article – thank you! We suspect we know where mice are running within a wall – but we’ve plugged their entries into the kitchen. Does the plug-in or ultrasound option still work to get the mouse out of the building completely? Was planning to get the plug-in and put it into the wall where we hear the noise.

    Is ultrasound or plug-in better for limiting any impact to our dog?

    Thanks again!
