Don’t be mistaken, birds are lovely creatures, maybe so much to you that you even feed them. However, there are a good number of reasons you might want to keep them away...


You have a beautiful garden or recently planted some flowers. But birds can deface the area with poop or disrupt the growth of the flowers.

Birds nesting around your house would quickly multiply their population in your yard. This can lead to property damage from scratches to your car, and again, bird poop all over the place.

Putting them safely in check isn’t rocket science:

All you’ll need is a quality bird repeller.

An ultrasonic bird repeller works effectively in casting away birds whenever they become pests in your home.

I’ve compiled a comprehensive list of the best ultrasonic bird repellers starting with our #1 favorite Bird-X Yard Gard Electronic Animal Repeller.

Bird-X Yard Gard Electronic Animal Repeller keeps unwanted pests out of your yard with ultrasonic sound-waves

Bird-X is a leading brand when it comes to producing safe and humane animal repellents. The Yard Gard is one of their top products, and it earns our top spot as the best bird repeller.

As the name suggests, it not only repels birds but larger animals such as rodents, raccoons, dogs, deers, etc.

Here’s the best part:

It has a coverage of up to 4,000 square feet. This makes the Yard Gard perfect for large homes, gardens, and even fields.

Another impressive feature of this device is its motion sensor. Once any bird is within 10 meters of the machine, it detects movement and emits threatening sounds to scare them off.

The high-frequency sound waves it emits are silent to most humans but irritate these animals. It has adjustable programming to set it to continuous use or motion-activated mode. The power is in your hands.

It works on 4C batteries, which can last for about one month of continuous operation. The batteries are not rechargeable, so they would need to be replaced regularly, depending on usage. It has a power cord so it can easily be plugged in if mounted close to an electricity supply.

To cap it off, this device is small and discreet. It weighs less than 3 pounds, which makes it portable enough to be installed anywhere.

Like most good things, this product has its flaws. While it is weatherproof, the device is not very stable in a moist environment.

Its ultrasonic sound and LED strobes help to scare off birds from your property.

It uses a ‘Triple Scan Technology,’ which allows it to detect birds 115 feet out for 12,000 square ft of detection. It would work effectively in an open space.

It has flexible functions for its LED strobe light, sound frequency. The frequency set would also determine who would hear the sound - If set to sonic, it would be heard by birds and humans, but at ultrasonic, it would be heard only by the birds.

The choice is pretty simple: trust me, no one wants to hear constant beeping noises.

It comes in three adjustable modes: always off, detection mode, and always on. Many tend to prefer detection mode.

It can work as a battery-powered (4D Batteries) or plugin. You would want to mount it close to a power source in your yard in case the battery fails.

What Should I Consider Before Purchasing An Ultrasonic Bird Repeller?

There are several bird deterrents on the market, so choosing one can become difficult. The goal is to scare off birds and not harm or kill them. Therefore, the ultrasonic bird repellent is considered humane. 

This is why electronic deterrents are regarded as more effective bird deterrents. But if you're willing to learn the ropes; which is an "oh-so-easy thing" to learn anyway, you'll never go wrong getting the best bird repellent of choice. 

Here are some tips that would help you make an informed decision before purchasing a repeller:

How It Works

Many people make the mistake of not understanding how a product works before purchase. Then installing and using it becomes a problem.

It is important to know what you are buying and why you are doing so. Ensure you have all the information about how a bird deterrent works before purchasing.

As I’ve mentioned, the devices give off high-pitched sounds to scare off birds. The frequency of these sounds could be between 15,000 – 30,000 Hz, which destabilizes the nervous systems of birds.

Many repellers use alternating sounds, going back and forth. These sounds are so loud that the closer they get, the worse it becomes, and their instinct is to run. Some devices have flashing lights as an extra deterrent method.

As many recent repellers are motion-activated, the birds do not even need to be very close before the sound goes off.

Applicable Bird Species 

It is of great significance to know the kind of birds you’re trying to get rid of before buying a bird deterrent. The first thing to know is the hearing range of most birds, which is between 1,000 - 4,000 Hz.

This range will easily repel unwanted species such as starlings.

Birds like pigeons, seagulls, sparrows are the exception. Pigeons specifically detect infrared sound (below human hearing range) and not high-pitched sound. Therefore, choosing the right device would help to scare birds off effectively.


There are several reasons to consider safety. First, you want to ensure the bird repeller doesn’t kill the birds you want to scare off.

Equally, human safety is essential. Some ultrasonic bird repellers would emit a sound that grown human ears can pick. Also, ensure there are no new-born babies in the neighborhood as ultrasonic can damage a baby’s hearing ability.

Lastly, your pets might detect sound emitted from the device and become irritated. Ensure it is out of their range. Proper thought must be given before installing an ultrasonic bird repeller.


Depending on the area you’re trying to protect, the device’s coverage and capacity should be considered. Many ultrasonic devices work best in semi-enclosed or enclosed locations where the sound waves can bounce off the walls and ceilings.

If the problem is outdoors, ultrasonic devices that work well in large areas should be considered as well as those with waterproof speakers and control panels.

Battery Type

As many ultrasonic devices are installed outdoors, it may not be close to an electricity source. The best bet for outdoor use would be to go for those with solar rechargeable batteries.


It is never a good idea to spend beyond your means. As ultrasonic devices are usually more expensive (though safer) than other forms of bird deterrents, it is best to purchase a more economical model.

This way, you can chase away birds and not be worried about your bank balance.

Warranty and Maintenance

Warranty would vary from brand to brand. Buyers might have installation issues or buy a device that doesn’t suit their needs. Therefore, you should do a proper warranty and maintenance search of the brand you’re buying.

Do Ultrasonic Bird Repellers Really Work?

Ultrasonic bird deterrents are devices that emit sound with high frequency and loudness to chase birds or other unwanted animals without any adverse effect on human hearing.

Scientists believe the lowest frequency the human ear can pick up is 20 Hz and can handle frequency as high as 20,000 Hz without any discomfort. In terms of loudness, the human ear can hear sound from 0 – 85 decibels (dB). The standard speech is about 55 dB.

Conversely, the hearing range of most birds is between 1,000 – 4,000 Hz. Some species of birds, such as songbirds, can hear up to 20,000 Hz, while birds like pigeons can detect infrasonic sounds (0.5 – 10 Hz), which is below the human range.

The high-pitched sound produced by ultrasonic devices is far from the human hearing range, but it falls within the hearing capacity of birds.

What Are The Types of Ultrasonic Bird Repellers?

Indoor vs Outdoor

Ultrasonic bird repellers can be categorized as indoor or outdoor use. Indoor devices are used for small houses and can be put in garages or patios. The outdoor gadgets have more coverage and are great for yards, gardens, farms, and fields.

Low vs Moderate vs High Frequency

It can also be categorized based on the level of sound frequency. They can be low-frequency (under 10,000 Hz), moderate (10,000 – 20,000 Hz) and high frequency (above 20,000 Hz). 

The first two sound levels are audible to humans, so caution should be taken when installing it while the high frequency can be stressful to your pets.

Wrapping Up

That’s a wrap. Ultrasonic bird repellers are useful devices for preventing invasion from winged intruders without causing any harm.

Compared to other bird deterrents like spikes, ultrasonic bird repellers are a humane way to keep birds at bay without hurting them. They also save your time and work longer than other means.

If you can’t decide which of the reviewed repellents to go for, we highly recommend the Bird-X Yard Gard Electronic Animal Repeller. It has extensive coverage of about 4,000 sq ft and a motion sensor that triggers a blare once a bird is within its range.

Also, it’s portable, easy to use, and environment friendly.
