Hoont Advanced Repeller

  • ​Weatherproof
  • ​Battery or plug-in option
  • Motion sensor activated

Of all the ultrasonic bird repellents we've researched and reviewed, our top pick goes to Hoont Advaned Repeller.


Because of the repellers we've found, the flashing strobes and frequencies this unit emits seem to be working the best to repel birds as reported by its customers.  It is capable of emitting 3 different ultrasonic sounds depending on how you set the dials, to prevent birds and other pests from adapting to the noise.

It also features a solar powered panel on top of the unit which recharges the rechargeable batteries for extended use.

The last bit we really like is that the Hoont unit has a hard plastic shell casing built to withstand rain, snow, and ice.

How Do Bird Ultrasonic Repellers Work?

The idea or concept behind ultrasonic repellers is actually quite simple.  They emit a high-frequency tone or noise, usually in 15-20 kHz range and above.  

This is outside the normal audible range for human beings but well within the audible hearing range for many animals and insects.  You may have heard how dogs will howl when a dog whistle is blown (also outside of human hearing) because it hurts their ears.  

The same thing holds true with ultrasonic repellers.

Moreover, many repellers will use alternating sounds, going back and forth much like a European police siren.  If you've ever heard one of them, you know they're incredibly annoying.  If you haven't, click on the link above and you'll see what we mean.  

After only a few moments you want to clap your hands over your ears and hit “stop” to put an end to the caterwauling of those things.

But imagine not being able to stop it.  Imagine it getting worse as you get closer and closer to your destination​.  Basically, that's what is supposed to happen to birds as they approach the ultrasonic repeller, the sound is intended to be so annoying they tuck tail and run – or fly, as the case may be.

Many ultrasonic repellers also add flashing LED strobe lights and sonic (i.e., humanly audible) sounds as well.  The combination, alternating back and forth, should prove to be more than it's worth to the birds and they'll seek shelter somewhere else.

Another thing to note is the motion detection sensors most repellers have had added to them of late.  This is actually an excellent idea.  

The bird approaches thinking everything is fine.  It crosses the line where the sensors can detect their presence and suddenly, all you-know-what breaks loose.  Birds are very skittish anyway and the unexpected nature of the explosive noise and light adds to their fright, alarming them into flying away.

The following video is a short review on a particular ultrasonic animal and bird repeller.

Do Ultrasonic Repellers Really Work?

This is a little harder to answer.  There are two kinds of evidence to consider in trying to answer this question; scientific research evidence and anecdotal evidence.

Scientific research evidence is the evidence which has been collected in rigorous, carefully planned studies which should take place under controlled conditions, or at least in conditions where all the possible variables have been accounted for and taken into consideration.  

The research to acquire this sort of evidence requires a great deal of time and money to conduct.  In other words, it's time-consuming and expensive.

Consequently, very little research of this type has actually been done.  There are some articles on university websites that talk about repellers, usually denigrating them, but we've noticed they rarely quote any actual studies.  

They claim studies have been done but when you dig into it, there aren't any rigorous studies.  What little research has been done is almost anecdotal itself.

Anecdotal evidence is the evidence from first-hand, eyewitness testimony of people who have used the devices at their home or business and can tell you what happened to them.  

When considering the weight of anecdotal evidence, remember this is the same sort of evidence that is admissible in a court of law to find someone guilty or not guilty of a crime beyond a reasonable doubt.

In civil trials, the verdict often hinges on what is called the “preponderance of evidence” standard, and it can be enough to justify handing out fines of tens of millions of dollars in some cases.  So anecdotal evidence is actually very good, solid evidence that can certainly be considered.

The anecdotal evidence seems to be about 60%-40% in favor of ultrasonic repellers working.  A lot of their success hinges on the placement of them and how many are being used.

How Should Ultrasonic Repellers Be Used To Remove Birds?

As mentioned earlier, the most annoying sounds are the undulating, back-and-forth types of noises like European police sirens.  Those sirens were specifically designed to be annoying and attention-grabbing, by the way.

That's what you want to be done with ultrasonic repellers.

For this reason, we recommend getting a minimum of two repellers at a time. Three or four would be ideal, but two is the bare minimum you should get.  

Set them up so their range overlaps by about 2/3's but far enough apart that they won't be triggered at the same time.  Then, when the birds fly into the “trigger zone” they'll be hit with different noises and flashes of light from two different directions, all of which are out of sync with each other – creating that undulating, alternating noise that will drive the birds crazy.

Place the repellers against a solid wall or large tree trunk.  This will bounce the sound waves back into the open area in front of the device.  Whatever you do, don't put them down on the ground even if the directions state that you can.

The closer they are to the ground the more “clutter” there will be break up the frequencies.  You're trying to frighten away birds that are flying in the air so putting the repellers on the ground seems counter-productive anyway.

Many of the repellers allow you to set different frequencies when you turn them on.  If possible, turn each repeller to a different frequency to increase the “police siren” effect.  You might even consider getting several repellers, one from each of several different manufacturers.

Experiment with different settings, placements, and patterns.  Just because you're not getting results one way, doesn't mean you won't get good results by using them in a new configuration.  

Play with it a little bit.  Do your own research.  You might find yourself pleasantly surprised at the outcome.

Top 5 Best Ultrasonic Bird Repellents Reviewed

As a quick recap, here are the top 5 ultrasonic bird repellents we looked at. Our #1 pick goes to the Hoont Solar Powered Ultrasonic Repeller because of the solar panel/USB options for charging the batteries.

  • ​Gets rid of all types of animal intruders
  • ​Flashing LED strobe lights
  • ​Solar powered and easy to install

This an upgraded, newer model that comes equipped with motion-activated ultrasonic sounds and LED strobes that flash aggressively to frighten away birds.  The motion sensors detect motion from up to 30-feet away.

There is a multitude of different settings including 3 separate ultrasonic frequencies, 7 sensitivity settings, and an on/off switch for the LED's. Constant changes in the setting ensure that birds aren't able to grow accustomed to it.

It has a solar panel on top for recharging the 3 AA batteries that are included with it.  It can also be recharged via a USB connection (cable included).  

It's also weatherproof and water resistant.  This works best when there are two of them in different locations, to “whiplash” the birds back and forth between them.

The instructions that come with it are a bit confusing, and there is an audible alarm on setting # 4 that can be very irritating.  Once it goes off you simply have to wait until it shuts off.

    ​Water resistant

    Senses motion up to 30-feet
  • Solar panel recharges batteries


  • Instructions are confusing and unclear
  • ​State of the art Triple Scan Technology
  • ​High intensity adjustable ultrasonic sounds

This is a motion-activated sonic/ultrasonic repeller for birds that includes powerful LED strobe lights to scare them away.  The sonic alarm is audible to you and me, whereas the ultrasonic noises are only audible to the birds and other critters.  

The LED's are dazzling and painful to the eyes, which will discourage all sorts of birds and pests.  The high-intensity sounds and LED's are adjustable for best results.

This includes something called “Triple Scan Technology” which allows it to detect motion out to distances of 115 feet for 12,000 square feet of detection area coverage.  

It can be set to three different modes: always off, detection mode, and always on.  The detection mode is probably the preferred mode since it will turn itself on only when it detects motion in the area, then turn itself off again when the birds leave.

Be careful of where you place this device.  Depending on what reflective or sound absorbing surfaces are nearby, it could work wonderfully or not at all.  It runs off of batteries or can be plugged in.  

It can also be mounted on a wall or tree, it can set up free standing.  It is water resistant but not weatherproof.

  • Motion activated up to 114-feet


  • ​Not weatherproof
  • Requires careful placement
  • ​Adjustable settings with 900 square feet coverage
  • ​Safe, humane, and easy to operate

Ultrasonic bird repeller puts out 90 dB of sound pressure at 1 meter. There is an adjustable frequency range of 15 to 25 kHz to cover up to 900 square feet.  

This is beyond the range of normal human hearing so it is harmless to children, it is but well within the audible range of birds, and works to scare them off.

This repeller is battery powered but includes a 50-foot extension cord for plugging it in.  It can be free standing or mounted to a wall, post, or tree.  

The perfect size and coverage area for keeping your patio or deck free of unwanted avian visitors, although the back can be fairly difficult to remove to change the batteries.  Needs a bit of work there.

This product is well suited to smaller areas in apartments where the manager can't (or won't) be bothered to do anything about noisy birds disturbing your rest or messing up your deck or balcony.  We've also heard from one person that this drives away bats.

    Great size for apartment balconies


  • Back is difficult to remove
  • Will not work on large areas
  • ​Powerful ultrasonic waves and strong LED flashing lights
  • ​Large coverage protection

This solar powered repeller has 5 different modes, adjustable for the frequency and LED flashing lights.  The motion sensors can detect movement up to 30-feet away for 5000 square feet of coverage.  It uses passive infrared to detect motion.

The solar panel charges the Lithium batteries, or they can be recharged via the included USB cable.  It has a spike on the bottom which makes it great for the backyard or for camping.  

The batteries charge quickly and have a good life before recharging again.

It has twin speakers for alternating sound to produce the maximum amount of irritation possible, and the LED strobes are even more frightening to birds and animals, scaring them away.  

It is water resistant but not weatherproofed.  May be subject to heat and cold.
