Do Ultrasonic Pest Repellers Work on Roaches?

Last Updated: 16.04.24


There are many products that will help you chase away annoying intruders such as rats, mice, coyotes, or many others, and some of them might have both advantages and disadvantages. Among the ultrasonic pest repeller side effects, we can remember the fact that some breeds of dogs might be able to hear the sounds and they can become a bit uncomfortable.

Some folks can be disturbed too – it depends on how sensitive a person is and how delicate his/her hearing is. Although there are only a few situations when dogs/humans were disturbed by these devices, you should take multiple facts into account before making a decision. It is better to be on the safe side, especially when it comes to your health or that of your beloved pet.

It would also be interesting to know if these ultrasonic pest repellers truly work on all types of insects, including roaches. In order to clarify this matter, we will need to understand how these devices work and if they are suitable for your needs. As we have already mentioned, there are many ways to chase away pests, so maybe a different option will work better for you.


How do ultrasonic pest repellers work?

We have all heard about ultrasonic repellents, but how do they actually work? The answer to this question is quite simple – they emit sounds at a frequency that the human ear cannot hear. But, the sounds are high and disturbing enough to chase away pests from your premises. This means that it is totally safe for humans and bad for your unwelcome guests.

Thanks to the rapid growth of technology, anyone can now enjoy a safe and clean environment free of cockroaches, fleas, rats, mice, and others. These pests will just run like crazy when they get close to these types of devices. The best part about most of them is that they are super easy to use – you just need to plug them in and you are done!

But, it is believed that chasing away mice and rats with ultrasound devices alone might not be the best and the smartest idea. Many people strongly recommend that you use them together with the traps! By doing this you will ensure that the rodent issue is fixed 100%. The ultrasound high-frequency sound waves will drive the rodents out of their hiding right into your traps.

Another important characteristic of these devices is that they can be short range and sometimes, depending on the device that you own, the range can also be weak. Moreover, if you want to avoid any delays in driving away pests from your property, you need to make sure that the ultrasounds are not blocked by walls or furniture.

How do roaches react to ultrasound repellers?

We have learned that ultrasonic pest repellers can affect a pest’s nervous system with the high-frequency sound. But what about cockroaches, how do they react? Well, cockroaches can detect these sounds through special hairs, but it is believed that they are not extremely bothered. Just because crickets get super annoyed, it doesn’t mean that roaches will get, too.

Some people say that mosquitoes, ants, or spiders are not bothered by the sound – they will just become a little more active than usual and will start moving around more. However, there are a lot of people who say that these devices really helped them keep their home free of roaches. The opinions are different, which means that nobody knows for sure if they will work or not.

There are some individuals who stated that they have noticed amazing results in the first few weeks and that afterward the roaches would not be disturbed by the sounds as they had gotten used to them. With this in mind, it is entirely up to you if you want to give it a try and see if it works for the type of issue you are facing.

Ultrasound pest repellers are a great alternative to chemicals, and it would be great if they could chase away those disturbing roaches. Another thing that can help you keep insects as far as possible from your home is to maintain your kitchen and basement clean all the time. This way there will be no temptations to attract them to those places.  


A safe alternative

Our health is the most important, and that is why you should know that these devices are a safe way of chasing away pests. Instead of getting rid of annoying intruders with sticky traps, various pastes, and liquid baits, people prefer ultrasound repellers as they are less hazardous especially when children and pets are around.

Pesticides are not only dangerous for your health but not using them in accordance with the label directions also means that you are violating the law of the USA. Nowadays, more and more people are embracing these hi-tech devices instead of resorting to those solutions that are considered outdated.

It is important to know that these devices do not guarantee complete pest eradication, but studies do show that they can cause a decrease in pest numbers. In order for the device to be effective, you have to choose wisely and it has to be suitable for your needs. First and foremost, it should be appropriate to the size of the area you will be using it for.

Moreover, there are certain types that work better on mice while others are more effective against insects. That is why you need to do some research in order to find out which is the one that will best serve your needs and only after that you should make a decision. A well-informed decision is one that you will not regret!

Are ultrasonic pest repellers effective?

We are sorry to disappoint you, but the studies undergone by various researchers are not too many which makes it impossible for us to conclude that these devices are effective 100%. Although they have never been proven to truly work, there are plenty of customers who are very satisfied. In other words, these devices may vary depending on particular situations.

There are certain animals who are not bothered at all by the noise, others that can get used to it in a short time, and those who feel very annoyed and run as far as possible from it. Moreover, there are certain species that can even get killed by these ultrasonic devices as they can experience audio-induced seizures.

Moreover, some studies show that these types of repellers can also disrupt certain natural habits in pests such as eating or mating. Just because the studies done on these devices are very limited doesn’t mean that they are not effective. We should also take into account those many individuals who swear by these products, as they have observed great results.

No matter how annoying pests are, they all hold some benefits for the environment, and that is why they shouldn’t be killed. Even if there are situations when pests can die because of these devices, in most cases they will just be chased away. This only makes us trust these devices even more, especially that they are safe for everyone involved – including pests.
