What is the best cat repellent noise?

You have a problem and want a humane way to keep cats out of your yard. Here at StopUpest.com I have researched the many ways to do this and I have found that the best cat repellent noise is an ultrasonic one.

Best Ultrasonic cat ScarerBelow I have made a lists of the top three best cat repellent noise modules on the market, both one for the USA and one for UK.

The main benefits are that ultrasonic noise irritates, annoys or scares cats but we humans are mostly immune to the ultrasonic, as it is out of our hearing range and it works!

In this post I’ll also let you know how they work and how effective they are at keeping your garden cat free.

USA best cat repellent noise unit

These top 3 selections don’t have all the features which some other ultrasonic cat scarers have nor are they the most expensive, but they have some of the best results and are value for money.

This is my number one choice for the best ultrasonic cat repellent that I have reviewed. The sensitivity and ultrasonic range is fully adjustable but simple to use and has great results.

This is Amazons no. one best seller in the ultrasonic repeller range. It is near identical to the 6-in-1 Pest Soldier Sentinel with its features and functions, but is has a “fiddly” back door and if not fitted properly is does let water in which destroys this otherwise great cat deterrent.

Again another simple and easy to use cat scarer and the UKs Amazon best seller.

All the above are great ultrasonic cat repellents, and if one is much cheaper than the others get it! You can check out the prices in the links above.

UK best cat repellent noise unit

With more features including solar battery charging and better priced than Amazons best-selling PestBye this is a clear winner.

Number 3 in the USA list but 2nd her because it’s much cheaper than the Yard Sentinel… And now with 50% off (at the time of writing) it’s Amazons best buy as well.

Ultrasonic Cat Deterrent Does It Work?

SonicBest Ultrasonic cat ScarerYou’ve got a cat problem and you want to know if an ultrasonic cat deterrent will work or not, or you want to know which is the best ultrasonic cat deterrent. Read on because here on StopUpest I’ve researched and reviewed many ultrasonic cat scarers and I’ll give you my results.

First up is a list of ultrasonic cat repellers one for the USA and one for the UK. They are in order of best first with a brief description. If you want more information there are links to reviews and more information.

USA list of Ultrasonic cat deterrent reviews

While this is the best ultrasonic pest deterrent it is near identical to the Yard Sentinal below but is has better results of cat free yards and reviews. Check it out on Amazon here.

Amazons best seller and very similar to the 1st place Pest Soldier Sentinel but knocked down a place by some reviews stating ill-fitting back plate leading to failure from water damage, but still a very good ultrasonic cat deterrent. Check it out on Amazon here.

This is also a great sonic cat scarer and best seller in the UK, but lacking some of the power supply features of the two above. Check it out on Amazon here.

DO NOT BUY! This made the list only to show you what a bad ultrasonic is. It’s cheap unreliable and has many bad reviews from other buyers. Check it out on Amazon here.

UK List of ultrasonic cat deterrent reviews

My recommendation for best UK ultrasonic cat repeller. This has most of the feature you would want in a maintenance free cat scarer, including solar charger and it is the cheapest sonic cat scarer. Check it out on Amazon here.


Amazons best-selling ultrasonic cat repeller knocked into 2nd place because of its price. It is very good at scaring cats away from your garden, I know because I bought one! Check it out on Amazon here.

A very competent cat deterrent and it is America’s best seller. Check it out on Amazon here.

Very easy to set up but unlike the repellers above that can target cats only the Mega-Sonic scares all animals. Check it out on Amazon here.

How does ultrasonic cat deterrent work

Hoont Ultrasonic Pest deterrentTo scare a cat the ultrasonic repeller first has to detect the cat, older models use motion detectors to spot anything that moves and blasts it with ultrasonic sound, and this unfortunately also included plants, leaves and trees causing the battery to run down very quickly.

Modern sonic cat scarers now use PIR (passive infrared) sensors, which detects the heat and movement of a cat giving fewer false alarms and it also works just as well at night.

Once the sensor is triggered the cat repeller emits a loud ultrasonic blast which either scares the cat or makes it uncomfortable for the cat to stay in your property.

Cats like to poo in tranquil private areas, you now have to train the cat which is a creature of habit to stop using your flowerbed as a litter tray. The ultrasonic blast is extremely irritating to cats and as mentioned above this is not how they like to do their business, but as creatures of habit they will keep coming back hoping for the good old times of peace and tranquillity. It may take them a while before they move to a new area to poo so have patience and perseverance.

Ultrasonic cat deterrents take time! Your cat repeller is not broken if there is no immediate results. If you see no results after a few weeks you mat have better results if you use both ultrasonic and scented repellers together.

What to look for when buying an ultrasonic cat deterrent

There are 3 main things to look at when buying an ultrasonic cat deterrent:

  1. The motion sensor
  2. The type of ultrasonic frequency
  3. How the unit is powered

Motion Sensor

There are 2 types of sensor; fixed or adjustable. If the area you want cat free is large with no pathways or driveways where passing traffic, pedestrians or even yourself can set off the motion sensor then a fixed senor is OK, however if you do have a smaller area you want covered then you should look for a model with an adjustable sensor.

Ultrasonic frequency

Different species are affected by a different range in the ultrasonic frequency, cats by one dogs by another and birds by yet another.

Ultrasonic cat repellers have two types of frequency settings. There is a non-adjustable unit and this will blast the cat with the full spectrum of ultrasonic sound, this will scare / annoy the cat and also all other animals / birds as well. If you want an animal free yard then this is the route for you.

If you want to target just cats then you need to look for an ultrasonic cat deterrent that has an adjustable frequency setting.

How to power the ultrasonic cat repeller.

There are many ways to power a sonic cat scarer:

  • Mains power
  • Battery power
  • Solar power
  • Car cigarette lighter
  • DC power

It all comes down to you and your situation also where you are going to place your cat repeller. However I personally would go for a solar rechargeable, if there is enough sun the batteries should last about a year before you would need to recharge them fully, making it fairly maintenance free.

6-in-1 Pest Soldier SentinelWhile looking for the best ultrasonic cat deterrent the 6-in-1 Pest Soldier Sentinel has stood out for having some of the best user reviews and positive results.

I believe it is a blatant copy of the best-selling Yard Sentinel but it is more reliable and cheaper. Check out my full review here or find latest price and more reviews on Amazon here.

UK best ultrasonic cat deterrent

Selections GFA805 Ultrasonic Cat scarerThe Selections GFA805 Ultrasonic Cat Repeller first came to my notice as the cheapest ultrasonic cat repeller, fully laden with all the best features I though this is too good to be true! It must be cheap and nasty, where is the cost cutting to be found?

Apart from the supplied rechargeable batteries I found no cost cutting and the user reviews were glowing and positive.

Note: Amazons best-selling PestBye Cat Repeller has reduced its price to match the Selections GFA805 but it still lacks a solar battery recharger.

Conclusion Ultrasonic cat deterrents

Best Ultrasonic cat ScarerUltrasonic cat deterrents do work! They are not 100% effective but in most cases they will keep cats out of your garden.

They are not expensive and are easy to use and can be maintenance free, just set and forget.

Ultrasonic blasts are a humane way to repel cats without harming them or your garden.

If you have tried free home-made or shop bought repellents that confuse their sense of smell but have not worked, then Ultrasonic cat deterrent should be your next choice of action.

I hope you have found this post from StopUpest.com useful. If you know anyone else that would like to keep cats out of their yard please share this post. Thank you.

Best Sonic Cat Repeller Reviews

Best Ultrasonic cat ScarerI’ve compiled two lists of Sonic cat repeller one for the USA and one for the UK.

Here at StopUpest.com I have been looking at ways to stop those pesky cats from pooping in your garden.

I’ve found that this problem has many varied solutions to keep cats out of your yard, from homemade scented cat repellents to shop bought state of the art cat deterrents.

In this post I’m concentrating on sonic cat repellers as they are among the most successful and easy ways to eradicate your pest problem.

I have found that sonic repellers can be feature rich and expensive but are out performed by simpler but better built sonic cat scarers.

I have compiled a list of sonic cat repellers that I have reviewed on StopUpest.com with my most recommended first, then going down the list from best to worst… In fact for the last one I recommend you don’t buy it’s that unreliable!

Sonic cat repeller Reviews USA

This is the best sonic cat repeller that I have reviewed. It is fully adjustable but simple to use and has great results.

The Yard Sentinel is Amazons best seller. It has near identical feature to the 6-in-1 Pest Soldier Sentinel but is has reliability issues and not as many positive cat scaring results on average.

Again another simple but effective sonic cat repeller

The PestAway ultrasonic repeller is a fully loaded model with flashing lights and simpler to use functions. However you are not able to target just cats with this but it will scare all wildlife from your garden.

I’ve left this in as a sample of what is a bad buy. This while looking good on paper has many reliability problems and bad reviews from other buyers.

Sonic Cat Repeller Reviews UK

Americas best-selling ultrasonic repeller now over here

Cheaper and better than Amazons best-selling PestBye

Number 3 in the USA list but it is very good and in the UK it is extremely cheap… And now with 50% off (at the time of writing) it’s Amazons best buy as well.

A good easy to use sonic repeller with the option to connect to the mains for power.

Are sonic cat repellers any good?

Sonic cat repellerNo cat repeller is 100% efficient! You are targeting animals with personalities ranging from the timid to the belligerent, the old and young, the deaf and blind.

Good newsUltrasonic cat repellers do have a very good success rate. Even though sonic cat repellers are advertised as cat scarers, this is not what will keep cats away from your garden. We have to make it very uncomfortable for cats to do their business in your flowerbeds and on the paths.

Cats like peace and quiet and the sonic repeller will not allow that! But that’s still not the whole story, you have to train the cat that your garden is not a tranquil litter box but this may take time.

Some cats learn very quickly before they move on and find somewhere new. however for some cats it can take months even up to 3! So be patient and don’t expect instant results.

Cheapest Ultrasonic cat repeller Selections GFA805 Solar Powered Battery Operated Ultrasonic Cat Repeller review

Cheapest Ultrasonic Cat Repeller

Selections GFA805 Ultrasonic Cat scarerThe Selections GFA805 Solar Powered Battery Operated Ultrasonic Cat Repeller is the cheapest sonic cat repeller on the market. How do they do it? It has great functions and even a solar charger… so let’s go through its features and see if it is too good to be true.

If you have found this page and looking to just buy the Selections GFA805 ultrasonic Cat Repeller please click the Amazon link HERE, where I have found the best price along with great service and quick delivery.

In this review I’ll look at the features and compare them with the bestselling Pestbye ultrasonic and see if they are better or not. I’ll go over the features, letting you know if they are useful or just marketing fluff.

I’ll find other owners thoughts about this cheap ultrasonic scarer and see if there are any major faults with it. Finally I’ll give you my conclusion and recommendations about the Selections Ultrasonic Cat Repeller.

Features of the Selections GFA805 Solar Powered Ultrasonic Cat Repeller.

  • Activated by a Passive Infrared Sensor

No cat can hide from this sensor, working day and night and any weather conditions the infrared sensor can detect the heat from a cat up to 22ft (6.7m), which in turn triggers a sonic blast at the cat.

Comparing this sensor with the PestBye it has the same detection range… no corners cut here.

  • PIR sensitivity adjuster

Staying with the infrared sensor, just like the Pestbye this is fully adjustable for sensitivity. There are 2 ways to use this. You can adjust how far away the sensor will work, for example if you have a path at the end of your garden you don’t want the ultrasonic repeller going off, draining its battery every time someone walks past.

Or you can adjust for the size of pest you want to repel. Not only does the Selections GFA805 Ultrasonic Repeller work on cats but also big dogs, foxes, squirrels, rodents and right down to insects.

  • Frequency adjuster

A frequency adjuster is included as well. Some ultrasonic scarers don’t have this and just blast away using the full frequency range, this will scare cats away but also every other animal in your garden including birds.

Being able to adjust the frequency you are able to target just one particular pest (cats) and still have birds visit your garden

  • Weatherproof

My research and reviews of other ultrasonic repellers show that many break down due to rain. Looking at owners comment for this one there has not been one complaint of failure due to rain. Big thumbs up for the Selections Ultrasonic Cat Repeller.

  • Solar Panel

So far this Ultrasonic repeller has stood up to the best-selling PestBye, now it surpasses it for features by including a solar panel for recharging the batteries making this repeller maintenance free. Depending on the weather and position of the unit the batteries can last from 3 months up to a year!

  • Rechargable Battery

Batteries are included…Yet another plus point over the PestBye which has none.

  • USB cable

Every now and again (depending on the amount of sun) the batteries will need recharging and the Selections GFA805 comes with a USB charger, unfortunately you cannot run the unit from the mains as it turns the detector off while recharging.

Check out the latest price here

  • Flashing light indicates low battery

An easy to see visual flashing light lets you know when the batteries are low. No worry about finding piles of cat poo in your garden because the ultrasonic cat scarer has stopped working.

  • Mounted on a spike or hung from a wall

Easy to set up… Point at the area you want to keep cats out of your garden and simply place in the ground or hang on a wall or post

  • Repels other pests

As mentioned above the Selections GFA805 Solar Cat Repeller can keep your garden free from other pests as well as cats. These include dogs, foxes, squirrels, rodents and insects… Also probably every other animal with ears.

  • Inaudible to humans

The ultrasonic noise should be inaudible to most humans… The older you are the less chance there is of you hearing the sonic sound.

  • Protected area radius 6-7m (22foot)

The area of protection is very similar to the PestBye and other ultrasonic repellers

Owners Comments

It works! At least for most people, unfortunately there are a minority of cats that seem to be immune to the sound and carry on as usual. (no cat repellent is 100% effective)

One fault that I came across was that the batteries supplies are not very good (the first bit of cost cutting) and better rechargeable batteries should be purchased.

Selections GFA805 Ultrasonic Cat scarerConclusion

The Selections GFA805 Solar Powered Ultrasonic Cat Repeller is not only as good as the bestselling PestBye cat repeller but it is in fact better, added to that it’s also cheaper making this a fantastic buy which that I’m sure will soon be Amazons top seller.

UPDATE: The PestBye as reduced its price to compete with the Selections GFA805, but is still is not as good due to lack of solar recharging.

Where to Buy the Selections GFA805 Ultrasonic Cat Repeller?

Which Is The Best Ultrasonic Cat Repeller USA 2017?

I’ve researched and reviewed many cat repellers and my research has shown that the best ultrasonic cat repeller sold in the USA is the 6-in-1 Pest Soldier Sentinel.

I’ll explain my reasons and criteria and tell you why I believe the 6-in-1 Pest Soldier Sentinel is the best. But If you don’t want to read my reasons and just want to keep cats out of your garden you can read my full review here or click here to go straight to Amazon to purchase or check it out.

Best ultrasonic cat repeller – Why this is my choice

While not the most feature rich sonic blaster the 6-in-1 Pest Soldier Sentinel compares well with Amazons best seller the Yard Sentinel, has better results at scaring cats, more positive comments and overcomes a flaw that many ultrasonic pest scarers suffer from and that is it’s totally weatherproof.

While not the cheapest it is competitively priced and here we are paying for reliability and quality. You want your cat scarer to continue working years down the line and not until the first rain storm.

A quality feature is that it is fully adjustable both in sensitivity and more importantly you can set it to target just on type of pest not everything with ears. For example you may just want to deter cats from coming into your yard but still have birds coming into your garden.

The Soldier Sentinel can be used indoor, outdoor and even in vehicles due to its many ways of power input. It can be powered from the mains via its extremely long power lead, or from a DC power source or just ordinary AA batteries.

It is very easy to set up and is also discreet. Its size is small and colored green so it can be placed on the ground or hung from a wall or post without spoiling the look of your garden.

The most important reason that the 6-in-1 Pest Soldier Sentinel is the best Ultrasonic cat scarer is because it works. It has above average reviews for success for clearing cats out of gardens than the other cat repellers in its class, and let’s face it that’s what we want!

How to set up the 6-in-1 Pest Soldier Sentinel

The Pest Soldier Sentinel is extremely simple to set up and once done you can forget it and let it get on with its job.

It has 2 adjustable setting.

  • One that adjusts the sensitivity of the sensor.

You may want to keep a small are free from cats or have a path at the end of your garden and you will not want the ultrasonic blaster to go off every time someone walks past.

  • The second adjustable setting is for the type of pest you want to scare away.

Different pests find different pitches in the ultrasonic range more annoying than others, also younger and older animals are also affected by different pitches. You may have to experiment here.

Next is to position the 6-in-1 Pest Soldier Sentinel, just point it at the area you want cat free. You can place the unit on the ground or higher up on a wall or fence.

Turn it on and you should have a cat free garden, it’s as simple as that!


Another reason for choosing the 6-in-1 Pest Soldier Sentinel is its price. Right now there is a price war on; you can check it out here at Amazon where you will get a great price with the knowledge of a fantastic service with super-fast delivery.

Along with its great price, quality fully adjustable settings and great results for a cat free garden I believe the 6-in-1 Pest Soldier Sentinel to be the best ultrasonic cat repeller for 2017.
