Squirrels have evolved to have a keen sense of hearing to detect the presence of predators. Read the entire article for more information on sounds to scare off squirrels.

List of Sounds Scaring Squirrels Away

while squirrels generally seem to hate things with strong scents. Certain noises can commonly frighten away squirrels. To detect the presence of predators, squirrels have evolved to develop a keen sense of hearing.

Human Noises To Scare Squirrels Away

Squirrels often run when humans arrive, but occasionally they become used to humans and their noises. Squirrels won’t rush too far when humans are nearby since they understand that humans don’t pose a significant threat.

Since humans do not typically behave as normal predators toward them but instead terrify them with their noise, researchers believe that they adapt their antipredator behavior. 

These researchers discovered that squirrel flying distance was correlated with park activity, even in public parks. Squirrels approached people more closely in crowded parks where people were continually walking past. Since they didn’t frequently engage with people and thought of them as a threat, squirrels preferred to avoid parks with fewer visitors.

Squirrels Hate Loud Speakers

Squirrels may not enjoy loud headbangers like many of us do. Outdoor speakers playing loud music can aid in keeping squirrels at a safe distance. According to one study, playing loud music caused squirrels to run an average of more than 22 feet away—an increase of more than 9 feet from the group in which music was not playing.

While loud music isn’t a permanent answer, playing music at a moderate intensity during the day can keep squirrels away. When the squirrely nutters come too close to your house, you may blast some music using outdoor speakers.

Birdsong To Scare Squirrels

Hearing birds sing is not like hearing humans. Squirrels are curious creatures who pay attention to what is happening in the forest around them, especially what the birds are chatting about.

The squirrels may learn from birds chirping if the environment is safe or if they should be concerned. Squirrels typically interpret common song patterns as some level of safety. But when one team of scientists played red-tailed hawk sounds, squirrels became more watchful and apprehensive of their surroundings.

This suggests that squirrels were quite aware of the types of birds present and perceived the predator bird’s chattering as a larger threat.

Barking Sound

This is a clear response if you have a dog. Dogs bark at squirrels, and because they are an evolutionary predator of squirrels, squirrels will run if they hear a dog barking. Some people attempt to scare squirrels away by playing recorded dog barking if they are observed damaging gardens.

Barking expands the area your dog considers as their territory. This explains why they frequently bark at wild creatures like bunnies, birds, and squirrels. However, if your dog is social, it might be barking to entice the squirrels to approach them.

Sound Of Large Predatory Bird

Squirrels might be scared away by the sound of any loud predatory bird. Using their motion-activated sounds and movements, devices like the BUBOBOSS Fake Scarecrow Owl Decoy can assist in safely dispersing the squirrels. This makes a great two-for-one combination with the scents that squirrels detest to keep them away.

Ultrasonic Noise

Ultrasonic noise is the noise that is played at an extremely high frequency. It can be extremely loud and even painful for squirrels and other rodents. There are many ultrasonic repellents available to keep squirrels at bay.

When something moves by the device, the motion detectors they use generate a loud sound. Because it doesn’t use offensive odors or dangerous chemicals, this sound is a popular deterrent that only specific animals can hear.

Squirrel-Repellent Sound Devices

Devices that make noise to repel squirrels may be an appealing option for your rodent problem. They are a harmless, natural technique to get rid of squirrels. Pests can all hear this high-frequency sound.

Squirrels near your property will be frightened by the ultrasonic sound waves and stay away from them. Therefore, since ultrasonic sounds irritate squirrels’ ears, they are deterred by them.

Horns Of Wind

Wind chimes can serve as a passive noise deterrent to ward off unwanted animals like squirrels. It’s not advisable to use only wind chimes because squirrels will grow accustomed to them after a week or two and stop being terrified of them.

Squirrels can be kept on their toes by changing the sound of the windchimes from high-pitched metallic windchimes to a more subdued chime.


Firecrackers emit a very loud, gunshot-like sound when lit and set off. Never hurl fireworks at an animal directly. It is better to dispose of them in a place far from people and animals, and you should only use them if qualified. The squirrels will be startled and alarmed by the firecracker’s loud noise. They’ll probably turn around and dash back into the trees.

Other Option For Repellent Sounds

You may do a few different, simple things to deter these pests. Vegetation that frequently acts as a seductive food source can be removed.

You can ensure that the trash cans outside are shut tightly and that the chimney, vents, and other openings are blocked. To keep away, a 1/4-inch wire mesh should be sufficient. Finally, be careful to swiftly collect any fruit that has fallen from trees and not leave pet food out longer than is necessary.

They will only want to stay if food or warmth is provided. Using this method is more successful than attempting to scare off squirrels with noises.


A great strategy to scare away neighborhood squirrels is to turn on bright lights or turn up the music loudly. While ultrasonic rodent repellant may work as well, kids and teenagers may become irritated by its high frequency.

Ultrasonic noises deter squirrels because they find them unpleasant to hear. Confusion, bewilderment, or even the inability to communicate with one another may result from it. Squirrels are easily frightened by high-frequency sounds, therefore they leave the area where they hear them.

Will A Radio Sound Keep Squirrels Away?

Yes, Radio Sound Keeps Squirrels Away. Radios set to dialogue could deceive squirrels into believing that people are around.
Your trash cans or chicken coop may attract squirrels, but the sound of the radio can scare them away. Consider often changing the channel, relocating the radio to various areas, and occasionally tweaking the volume to keep the squirrels guessing.

What Sound Frequency Do Squirrels Hate?

There is no clear answer because various squirrels appear to have varied aversion thresholds. In general, higher-pitched frequencies appear to work better than lower-pitched ones to repel squirrels. This makes sense because higher-pitched sounds make animals more prone to become irritated or uncomfortable.
The normal frequencies that irritate squirrel ears are between 20,000 and 25,000 Hz, with 25,000 being the typical threshold at which irritation becomes severe.

Are Squirrel-Repellent Sound Devices Short-Term Effective?

Sound repellents may be effective in the short term for gardening purposes, such as keeping squirrels away from a newly planted bed until the seedlings become strong enough to withstand harm.
Still, they are unlikely to offer a permanent solution. However, sometimes squirrels tend to adapt to these sounds. They become accustomed to not being afraid of anything when they continually hear a menacing sound without any risk.

How Do Squirrel-Repellent Sound Devices Work?

1- These gadgets produce high-frequency sound waves exceeding the hearing range of humans but at a volume that rodents like squirrels, rats, and others can hear and, initially, be bothered by. 
2- Most of these gadgets are electrically driven and can either be plugged into a socket or run on batteries. 
3- Additionally, it should be noted that because the US Environmental Protection Agency does not register these kinds of devices, the businesses that sell them are not required to give evidence that they function as advertised.
