Bat removal can be tough.

For effective bat control, you have to use specific methods instead of general ones.

For example, you have to employ pest control methods that would remove bats from your property instead of harming them. There are many methods you can use to get rid of bats, including non-contact ones.

An ultrasonic bat repeller is good for bat removal.

In this guide, we are going to show you use an ultrasonic bat repeller, the best ultrasonic bat repeller to use, and other ways you can repel bats.

Now, having a lot of bats in your home can cause some serious issues for you.

Bats flying about might cause a scare at night. Bat droppings, also known as guano, can spread diseases around your home. Although guano might look similar to mice droppings, it is usually bigger and lumpy.

Bats are also aggressive when provoked. It doesn’t mean they would bite you. It means if you try to get rid of them directly, they might just try to defend themselves by biting you.

Bat bites can infect you with different diseases, as they are disease carriers too.

To make matters worse for homeowners, bats are protected by several laws. Although these laws vary from state to state, it means you can’t just kill a bat because it’s on your property.

How then can you get rid of bats humanely without breaking the law? Here’s where an ultrasonic bat repellent comes in. But first, let’s see if ultrasonic frequencies work on bats.

Do High Frequency Sounds Repel Bats?

This may come as a surprise to you, but bats actually communicate in high frequency sounds!

The sound they release is ultrasonic, the same kind of sound emitted by an ultrasonic bat repeller.

Bats echolocate. This means they use high frequency sounds to know the precise location of food and of each other.

Bats see. They are not blind like most people think but they rely more on their sense of hearing to move around.

So high frequency sounds from one bat will attract bats.

But when this sound is coming from an ultrasonic device, it will scare away bats because it irritates them and passes no message.

Do bats hate ultrasonic sound?

Bats hate the ultrasonic sound that comes from sources other than each other.

Think of it this way: if you heard someone shouting over a public address system in a language you didn’t understand, would you respond?

You might want to get away from that area because you don’t understand what’s going on. 

Ultrasonic sound waves from ultrasonic bat repellents work similarly.

An ultrasonic bat repeller would emit an ultrasonic sound that disturbs communication within bats. 

The sounds would also confuse them, as they won’t be able to locate things with precision again.

So yes, bats hate ultrasonic sound and will stay as far away as they can from it.

Do electronic bat repellents really work?

They emit ultrasonic sound waves that disturb bats as we explained before.

Additionally, they do not cause any harm to bats both physically and others.

Ultrasonic bat repellent devices are also friendly to the environment as they do not release any harmful pollutants.

As far as you use them the right way, you will notice a significant increase in the reduction of bats on your property.

Can Ultrasonic Bat Repellents Harm You?

No. An ultrasonic bat repeller can’t harm you.

The human ear can’t pick up ultrasonic sounds, because they are out of our hearing range. So if you’re worried you would hear ultrasonic sound waves, you wouldn’t.

Would your pets hear the ultrasonic sound? Yes, they would be able to hear it, but it won’t cause any side effects. Ultrasonic devices won’t just repel bats, they will chase away other rodent and insect pests disturbing your home too!

Ultrasonic bat repellents cause no harm to bats. Bats are simply forced to roost elsewhere, meaning you are breaking no laws by using these devices.

So how do you pick the best ultrasonic bat repeller?

What Is The Best Repellent For Bats?

Ultrasonic pest repellents are not new.

In fact, this technology has been around for nearly two decades.

It’s easy for you to get confused about the best ultrasonic bat repeller to pick, as they all seem similar.

We did the picking for you.

The Ultrasonic Pest Repeller from Thanoshome is the best ultrasonic bat repeller, as it has several awesome features we’ll tell you about.

Long range

The Thanos® Ultrasonic Pest Repellent uses superior technology to emit long range ultrasonic waves.

Now with bats, you want to get a device that can reach them anywhere around your property.

If you’re dealing with insects like cockroaches, you might not really need a long range device.

But with bats, you need a device that can get them even in those crevices or in your attic.


The ultrasonic waves emitted from the Thanos Ultrasonic Pest Repeller High Power Ultrasonic frequency can be modified for different purposes.

This means you get different frequencies from the same device with no extra effort!

How To Use Ultrasonic Bat Repellers

To use ultrasonic bat repellers, there are some guidelines you have to follow.

If you use these devices carelessly, you might not get the kind of results you are looking for.

Worse still, you might think even the best ultrasonic bat repeller is a lie because bats still disturb you.

Here are guidelines for using ultrasonic bat repellers effectively:

Target areas where bats love to dwell

Bats love to stay in crevices around your home, on trees, and in hidden places around your lawn.

Instead of placing ultrasonic bat repellers just anywhere, put them specifically in areas where you see bats.

Buy a good number of repellents

There’s no way one bat repellent can take care of all the bats on your property.

If you want to see visible results, buy a good number of repellents.

Most repellents can cover a 40-mile radius, so the more bats you have, the more repellents you need.

Combine repellents with other methods: It’s not enough to use just ultrasonic bat repellents.

To get the best results, combine repellents with other pest control methods like baits.

We strongly advise you not to use traps as these can get messy.

You might even be accused of causing harm to bats, so it’s best to stick to an ultrasonic pest repellent and baits or scare tactics.

What other bat control methods can I use?


A mirror is a good bat repeller because it reflects light.

Bats hate the light and will avoid areas where reflected light reaches.


What is a better bat repeller than mirrors? Light itself! 
Light up your garden, attic, or any area you notice heavy bat activity.

Measure your progress

This step is very important because you can determine if the repellent works for you, or if you need to change strategy.

Let’s say you have 2 or 3 bats roosting in your attic. 

Place 2 ultrasonic pest repellers in your attic and watch their activity over one week.

If they move about as if nothing changed, know that you need to change your strategy.

If you see changes, it’s time to go full-on and buy as many repellers as you need.

Ideally, you should see a significant reduction in bat activity a month from using bat repellers.

Do Ultrasonic Bat Repellent Devices Penetrate Walls?

Yes. An ultrasonic pest repellent can emit sound waves that can pass through walls and ceilings.

This is why you need to get a long-range device, like the one we recommended.

Ultrasonic bat repellents use both ultrasonic and electromagnetic waves.

Together, these waves can pass through most objects.

Remember, the work of these repellents is to make your home as hostile as possible to bats, not to kill them.


Bats leave your home as soon as the ultrasonic deterrent starts to work.
A bat deterrent is specifically designed to reduce bat activity using humane methods.
