The Best Cat Scarers and Deterrents Reviewed

Last Updated on

For most home owners, the most effective cat scarer we would recommend would have to be the UltraSonic Cat Repeller by PestBye. This model has proven useful for thousands of people, is probably one of the most popular models and is perfect for using to protect larger areas such as lawns and large flower beds. It's easy to use, can be tweaked accordingly and is very effective for a lot of people including myself, more on this later. 

Best Pick

By the far the most effective model currently available, its not perfect but we estimate its probably effective for around 70% of people.

  • Produces a high frequency noise that quickly sends the cat fleeing but cannot be heard by humans.
  • Uses an infra-red PIR sensor which can detect cats up to 23ft away in a 80 degree arc protecting large areas.

The Cat Repeller Guide

Types of cat scarers and repellents

There are many types of cat repellers so in this section we are first going to look at some of the most popular types and explain the pros and cons of each and when then should be used.

Ultrasonic Cat Repellers

These types of cat scarers are probably the most effective overall and our first choice in the battle against deterring cats from your garden. They work by producing a very loud noise at a frequency that only cats can hear which sends them fleeing, the good news is it cannot be heard by humans. They are activated by a motion sensor and can cover around 369sq ft making it ideal for large areas such as lawns and large flower beds. Older cats may not respond if they have hearing loss and some cats may just not respond to the noise. 

Jet Spray Motion Activated Motion Repeller

These are a great alternative to ultrasonic cat repellers previously discussed, instead of using a high noise frequency to scare off cats, they use a water sprinkler setup to spray cats with water when the motion sensor is activated. As you probably know, nearly all cats hate water so these scarers have proven very good. 

Also great

The Defenders Jet Spray Repeller is most definitely effective and probably the best model out of all the water type models we have seen. It is painless to setup and covers a decent area. The construction is pretty solid.

Prickle strips (walls, fences and flower beds)

These are very effective if installed correctly, they don't harm cats as they are not sharp but cats do not like jumping onto them. You can buy these from many sellers but we found the best ones where made by a company called 'The Cactus', we first seen them on TV's ‘Country File’ with John Craven a few years back. You simply fasten them in strips to the top of walls and fences and they help deter cats from jumping into your fence. Cats have been known to walk on them so its best to install them where cats need to jump to get into the fence for it to be effective.

Cat repellents such as pellets, gels and granules

There are many different cat repellents granules and gels on the market that claim to repel cats but most seem to be ineffective, they can work around flower beds between plants, some gardeners say they work, others don't agree. I think it's simply down to the cats visiting there garden, it seems to repel some, while other cats may not be able to smell it, maybe . they just don't care.

Out of all the repellers the one we are most impressed with is Silent Roar, we have personally used this product for over 6 years and have found it seems to work which is why we recommend it here.

Problems caused by cat poo

Cats can actually become in your garden, specially if you are a keen gardener and have children help out in the garden which we strongly encourage.

First off, it's unpleasant to have cat defecating in your garden so you want to do your upmost to deter cats from doing this, we simply want to encourage them to do it somewhere else, perhaps  in there own garden.


Reviews of the best cat repellers

Below are detailed reviews of each of our top recommended cat repellers starting with our 'Best Pick'. We review each model in detail outlining the pros and cons of each as well as our conclusion on each model in terms of quality, effectiveness and whether its worth trying.


  PestBye Cat Repeller

What we found is that sonic car repellers seem to work best when used in large open areas so this is ideal for large open spaces and lawns which is what we would recommend them for. There are many different versions of sonic cat repellers from different brands but this model by PestBuy is almost certainly the best, easy to use, very well made and it seems very effective for most people, around 90% of people should find this model works for them.

We previously review a very similar model by PestBuy around 3 years and this is actually the updated model. This new and improved model, the PestBuy Ultrasonic cat repeller is one of the most popular types of cat scarers you can buy and its easy to see why, generally, it's the quickest way to scare cats off and well as the most successful for most people. 

We think that this model by PestBuy is probably the best ultra sonic type model out there (and theres a lot of them) and it has the reviews to further back up our finding and experience. On Amazon alone it has over 160 reviews.

So like all Ultrasonic cat repellers, It works by using a infra-red PIR sensor like that found on a house alarm too sense the cats movement, once activated it emits a high frequency sound which cats do not like and will leave the area as fast as they came. Its doesn't effect birds which means you can still encourage birds into your garden.

We like that It can cover up to 23ft (7 meters) at a 80 degree arc, that is an impressive total unobstructed working area of 184sq ft making it perfect for lawns or other large open areas.

It is fully waterproof and comes with a stake, so you can stake it into the ground or you can fasten it to a wall or fence which is handy. Its does take 4 x AA batteries which you need to buy separately.


Final Conclusion

What we found is that sonic car repellers seem to work when used in large open areas so this is ideal for large open spaces and lawns which is what we would recommend them for. There are many different versions of sonic cat repellers from different brands but this model by PestBuy is almost certainly the easiest to use, very well made and it seems very effective, around 90% of people should find this model works for them.

To be honest, we did find one alternative model by 'The Commander' which we really like and its probably just as good but this model but its more expensive which is why it didn't get the 'Top Pick' spot.

What we did learn is that some cats do learn how to avoid the sensor which is why it needs to be in areas where cats need to pass through. It may also help to move it around a bit to keep the cats on their toes so they find it harder to find an alternative root. Overall though, this is an excellent model and is very effective.

  Defenders Prickle Strip Dig Stopper

The Defenders Prickle Strip Dig Stopper is specifically designed for installing in planted grounds. If you have been struggling to keep cats off your flower beds, then the Dig Stopper is your perfect solution. You can even install this near fences or specific places where cats tend to jump down into planted areas.

The Defenders Prickle Strip Dig Stopper is designed for those who want to keep pets off their flowerbeds, seedbeds, containers, vegetable gardens, pots, and other vulnerable planted areas. This prevents animals such as cats, dogs, squirrels, and rabbits from digging in planted areas in a simple, yet effective manner. If animals try to dig at all, the prickle strip gives a tingling sensation to their feet, it doesn't cause them pain but does seem to really deter them from digging. You could put them just under the soil and seeding can grow through them while you can carefully place it around larger plants.

It comes in rolls that are 28cm wide by x 2m in length which is just over 6ft long, its a little fidderly but it can be secured in the ground with tent pegs or similar. They can be trimmed to size or connected together which we like so you can cover a large garden area if needed.

Install just below the ground level, this prickle strip allows seedlings to grow and find their way freely through the mesh to thrive.


Final Conclusion

The Defenders Prickle Strip Dig Stopper is specifically designed for installing in planted grounds. If you have been struggling to keep cats off your flower beds, then the Dig Stopper is your perfect solution that is nearly always guaranteed to work. You can even install this near fences or specific places where cats tend to jump down into planted areas but it better to use it to help deter them from digging. 

The spikes are very effective at deterring domestic felines but it doesn't cut them in any way, its more uncomfortable and helps to simply put them off digging. The strips are easy to cut, join and install, so you can buy as many to meet your garden requirements. We absolutely recommend this product for guarding vulnerable sections of your garden. Be sure to follow the installation instructions carefully for it to work perfectly. Overall a great simple product and very well made. If you have pots, it's probably the most effective way to stop cat digging in your pots.

  Defenders STV415 Jet Spray Repeller

The Defenders STV415 Jet Spray Battery Operated Fox Repeller and Cat Deterrent is most definitely effective, especially for the fact that cats run at the slightest sight of water. It is painless to install and covers a decent area. The construction is pretty solid and this unit is reliable all year round. Now we are not sure how much water this device uses, but that probably depends on how often animals come around.

The Defenders STV415 Jet Spray Repeller repels garden invading animals such as cats in a humane way, it's advertised as a fox repeller but it's perfect for using if you have a problem with the local cats. We think it's probably the most effective water sprinkler scarer we have seen and seem well made overall, it got a few design improvements such as the removable pop out battery compartment which makes changing the batteries much easier, specially if its at the other end of the garden. 

It's a brilliant but simple design, it uses a PIR sensor and a water sprinkler like that used on garden sprinklers. When something passes in front of the sensor, just like the Ultrasonic cat repellers, the device is activated and in the case of this model, directs a jet of water at the animal, hopefully a cat to scare it away. A harmless but very effective design. It’s a brilliant idea since cats naturally hate water, but this device is also meant to scare off foxes as mentioned. 

This has a coverage area of up to 10 metres in a 120-degree arc but can be set to only 2 meters using the black reach dial in top of the sprinkler, it creates a protected zone of over 100 square metres.


Final Conclusion

The Defenders STV415 Jet Spray is most definitely effective, especially for the fact that cats run at the slightest sight of water and the design is brilliant and quality is robust. We like that it is painless to install and covers a decent area.

As mentioned, the construction is pretty solid and this model is reliable all year round but will ether need disconnecting when frost is forecast (keep an eye on the weather forecast) or maybe try some lagging, don't forget if you try this the hose pipe would also need lagging.

Now we are not sure how much water this device uses, but that probably depends on how often animals come around. 

A 2 year guarantee on all its electronic components provides additional peace of mind should anything become faulty. If you are looking to protect vulnerable areas such as hen runs from foxes, beautifully mowed lawns, your beloved fish pond from pesky herons, then this deterrent is worth considering and will certainly do the job.

Cactus Fence & Wall Spikes

The reason for this is that the cats have actually been known to walk on the spike, but they WILL NOT jump onto them. For this reason they need to be placed where cats have to jump to get onto the fence or wall to be most effective.

The Cactus Fence wall spikes have proved very successful but there are many brands available and the one that stands out as being good quality and most effective is by a company called ‘The Cactus’ and they are UK made as a bonus, a real quality product.

These strips of spikes fasten to the top of your fence and will stop cats coming into your garden, they come in 4.5 meter lengths and you simply fix them to the top of your fence or walls, you can even put them on the top of play swing sets if you have a problem with birds sitting on them and pooing on the swing etc.

They don't actually harm the cat or animals that stand on them but they are very uncomfortable to stand on. ideally you set them up high, so that the cats or foxes have to physically jump up onto them, they don't like that and will soon be discouraged from doing that.


Final Conclusion

We first seen these on TV's ‘Country File’ with John Craven and were very impressed, these could really be the fix for your cat problem.

Some pointers to note is that we found you need to place them on a fence or wall that is fairly tall, 5 or 6ft or taller would be ideal, this mean the have to jump up onto the spikes rather than step on them slowly which some cats will still do, the idea is to deter them so they find an easier route to another garden.

Another tip is, if you split each strip into 3 narrow strips, one pack with cover 13,5 meters instead of only 4.5 meters and there still just as effective. Another tip we only recently learn is to bend them into half moons along the fence, we think this makes them much more effective too.

  Silent Roar

Silentroar Silent Roar Nitrogen Based Fertilizer 0.5kg

Silent roar has an interesting story and has proven very effective for some people and we have used it for over 6 years ourselves now which is why we strongly recommend it. We have a long history of success with using this product.

Being pellets it is recommended for smaller areas where cats are pooing in small flower beds in small areas of the garden. We recommend lightly raking it into the soil for the best effectiveness.

So what is is?, Silent Roar are actually fertiliser pellets which have been soaked in real essence of lion dung and dried. The idea is cats enter the area where the pellets have been spread and smell the scent of a larger cat (the lion). They then see this area as marked by another larger cat and move on to find another area, this makes sense as this is how cats and lions scent there territory to warn off other cats. It should last around 4 weeks being needing applying again.


Final Conclusion

You may notice that it is sold as a fertiliser and not a cat repellent and it took some research to find out why. It did use to be sold as a cat repellent but then new EU rules can in that meant that EU certification was needed as cat repellents are usually made up of certain chemicals and they need the relevant EU certification to be able to put on the packet that it is a cat repellent.

People have mixed views on Silent Roar, some say it works wonders, some say it's a waste of money, however, we think its worth a try as its seems to work for us in our own garden.

Final Conclusion

We first look at different cat repellents back in 2015, we have seen some improvements in design, specially with the water sprinkler type models, however what still rings true is that a mixture of a different types of repellents and scarers is the most effective way to deter cats.
