Do Ultrasonic Cat Repellents Work?

Ultrasonic cat repellents are devices that emit high-frequency sound waves to deter cats from entering an area. They’re often used by homeowners who want to keep cats away from their gardens or yards, but do they actually work?

The answer is not as straightforward as you might think. While some studies have shown that ultrasonic cat repellents can be effective in keeping cats away, other studies have found them to be ineffective. In addition, customer reviews of these products vary widely, and it’s difficult to draw any definitive conclusions about their effectiveness.

One study conducted in 2013 tested the effectiveness of a commercial ultrasonic cat repellent on a group of domestic cats over a period of three weeks. The results showed that the device was able to reduce the number of visits made by the cats during this time period, suggesting that it may be effective at deterring them from certain areas. However, further research is needed before any firm conclusions can be drawn about its efficacy.

Another study conducted in 2015 looked at how well different types of ultrasonic cat repellents worked when placed around garden plants and flower beds. The researchers found that while some models were able to successfully repel cats for short periods of time (up to two hours), others had no effect whatsoever on feline behaviour. Again, more research is needed before any definitive statements can be made about their effectiveness against felines in outdoor settings.

Customer reviews also provide mixed feedback regarding using ultrasonic cat repellers outdoors; some users report success with keeping unwanted felines out, while others claim they had no effect whatsoever on local strays or neighbourhood pets visiting their property uninvitedly. Ultimately, whether or not an ultrasonic cat repeller will work depends largely on individual circumstances and should always be evaluated carefully before purchase and use.

Overall, ultrasonic cat repellents can be a useful tool for keeping cats away from certain areas. However, it is important to consider the pros and cons before investing in this type of product. Next up, we will explore some of these advantages and disadvantages in more detail.

Key Takeaway: Ultrasonic cat repellents may be effective at deterring cats from certain areas, but research and customer reviews provide mixed feedback. Factors such as individual circumstances should always be considered before purchase and use.

Pros and Cons of Using Ultrasonic Cat Repellents

Ultrasonic cat repellents are a popular choice for those looking to keep cats away from their garden or property. They work by emitting high-frequency sound waves that cats find unpleasant but humans can’t hear. But before you invest in one of these devices, it’s important to understand the pros and cons of using them.


Cost-Effectiveness – Ultrasonic cat repellents are relatively inexpensive compared to other methods of keeping cats away, such as fencing or netting. They also don’t require any ongoing maintenance costs as some other solutions do.

Ease of Use – Most ultrasonic cat repellents come with easy-to-follow instructions and take just minutes to set up and use. Plus, they don’t require any special tools or skills, so anyone can use them successfully.

Environmental Impact – Unlike chemical sprays which may contain harmful toxins, ultrasonic cat repellents have no negative environmental impact since they only emit sound waves that cannot be heard by humans or animals alike.


Limited Range – The range of an ultrasonic cat repeller is limited, typically between 30 and 50 feet, depending on the model you choose. This means if your garden is larger than this, then you will need multiple units placed strategically around the perimeter to cover all areas where cats might enter your property.

No Guarantee of Effectiveness – While most people report good results when using an ultrasonic cat repeller, there is no guarantee that it will always work effectively as each individual situation can vary greatly due to factors such as wind direction, terrain type etc. Additionally, some cats may become accustomed to the sound over time, making it less effective at deterring them from entering your property in future visits.

Overall, it is important to weigh the pros and cons of using ultrasonic cat repellents before making a decision. However, there are other alternatives that may be more effective in deterring cats from your home or garden, so let’s take a look at those next.

Key Takeaway: Ultrasonic cat repellents can be a cost-effective and easy-to-use solution for keeping cats away, but they have a limited range, and their effectiveness can vary depending on individual circumstances.

FAQs in Relation to Do Ultrasonic Cat Repellents Work

Do cat repellents actually work?

Yes, cat repellents can be effective in deterring cats from entering certain areas. However, the effectiveness of these products depends on the type of product used and how it is applied. Repellents that contain natural ingredients such as essential oils or pungent odours like citrus are often more successful than chemical-based repellents. Additionally, for best results, repellents should be reapplied regularly and after rain or snowfall to maintain their efficacy. Ultimately, using a combination of deterrents, such as motion-activated sprinklers and barriers, may provide better protection against cats than relying solely on repellent products alone.

What is the best deterrent to keep cats away?

There are a few methods that can be used to deter cats from entering your garden or home. One of the most effective deterrents is motion-activated sprinklers. These devices detect movement and spray water in the direction of any intruding cats, startling them away without causing harm. Additionally, strong smells such as citrus peels, vinegar or essential oils can help keep cats away. Lastly, loud noises like clapping hands or shaking coins in a jar will also scare off unwanted felines. All three methods are humane and effective ways to keep cats out of your space.

Do cats react to ultrasonic sounds?

No, cats do not react to ultrasonic sounds. Ultrasonic sound is above the range of human hearing, and cats are unable to hear it. However, some research has suggested that cats may be able to detect infrasound frequencies which are below the range of human hearing. This could explain why some cats seem to respond to certain noises or vibrations that humans cannot hear.

Do electric cat repellents work?

They work by emitting a high-pitched sound that is unpleasant to cats but not audible to humans. This sound creates an uncomfortable environment for the cats and encourages them to stay away. Additionally, some models come with motion sensors which activate when a cat approaches, further reinforcing the deterrent effect. However, it’s important to note that these devices are not 100% foolproof and may require regular maintenance or replacement over time in order to remain effective.


In conclusion, ultrasonic cat repellents can be an effective way to keep cats away from your garden or home. However, it is important to consider the pros and cons of using them before making a decision. Ultrasonic cat repellents may not work for all cats, and there are alternatives that you can try if they don’t seem to be working for you. Ultimately, the answer to “do ultrasonic cat repellents work” depends on how well they fit into your specific situation.
