Hundeschreck mit Ultraschall – konfliktfrei und schonend - IREPELL

Dog Scare with Ultrasound – Conflict-Free and Gentle Solution

If a stray dog interferes with the tranquility of the garden on a daily basis, causing damage, leaving dog droppings in the garden, or even exhibiting aggressive behavior, it's time to act. However, especially when it comes to a neighbouring dog, this can lead to conflicts that you would rather avoid.

Ultrasound has proven to be an extremely effective dog scare and is also pet friendly and discreet. In this article, we therefore explain how ultrasound devices work, what advantages they offer and why they are superior to conventional deterrents. 


How does ultrasound work against dogs?

Ultrasound works against dogs by emitting high-frequency sound waves that are inaudible to humans but uncomfortable to dogs. Dogs have a much wider range of hearing than humans, reaching up to about 65,000 Hz, while humans can only hear up to about 20,000 Hz. 

The ultrasound emitted by the devices is usually in the range of about 20,000 Hz to 65,000 Hz and is irritating to dogs. This experience keeps the dog away from those areas where the sound pressure of the device is still perceived as annoying by the dog. People, on the other hand, do not perceive the sound.

The method exploits the natural hearing spectrum of dogs to achieve deterrence without causing physical harm to the animal. The dog links the unpleasant tone to the specific area and avoids it in the future. 

The automatic activation of the ultrasonic sound by motion sensors ensures that the sound is only emitted when a dog approaches the monitored area. In addition, innovative devices vary the frequencies or patterns of the sounds to prevent the dogs from getting used to the sound.

Driving dogs away with ultrasound – the advantages

The use of ultrasound to drive dogs away offers several advantages. One of the most important is undoubtedly that ultrasound equipment reliably drives away dogs, but does not cause them any physical harm.

The high frequencies emitted by ultrasound equipment are unpleasant for dogs, but they do not harm the animal. The ultrasound only makes them avoid the range of the device, but there are no further consequences for the animal. It is therefore one of the animal-friendly solutions compared to other potentially harmful methods. 

Another argument for the use of ultrasonic defenses is that the sounds are inaudible to humans. The frequencies used to repel animals are outside the human hearing range, so the devices do not constitute a nuisance or disturbance to neighbors or other people in the area. Sophisticated models not only work against a particular species, but can also be used as a marten scarecrow (for marten defense in the carport) or cat scarecrow through various modes. 

The easy installation and use of ultrasound equipment is also a great advantage if you want to use it as a dog repeller. They are extremely compact and can be easily installed at strategic points outdoors or in the home. Many models are battery-operated or can be connected to a power source and can therefore be used flexibly.

In addition, ultrasound devices often offer automatic activation when moving. A motion detector ensures that the device only emits sounds when a dog actually enters the monitored area. This saves energy and ensures that deterrence only occurs when it is necessary. For devices with battery or battery operation, this is an important function that guarantees long-lasting, reliable protection.

Ultrasonic distributors are also relatively easy to maintain. Unlike chemical repellents, which need to be reapplied on a regular basis, ultrasonic devices only require occasional battery replacement or charging. Devices such asIREPELL ®, which can also be connected directly to the mains, do not need to be charged at all.


The disadvantages of conventional alternatives

In addition to an ultrasonic dog scare, there are various other ways to keep an unwanted dog away from a property. However, many of these dog repellents are less reliable or have other disadvantages, such as high costs. 


The purchase of a fence is associated with some effort. A conventional pasture fence is often not sufficient, as a strange dog could slip under it or jump over it. The fence must be high enough and stable for effective dog protection, which is often associated with high costs. 

If you want to attract little attention because you want to avoid conflict with your neighbours, erecting a high fence is probably not very effective.

Dog repellent with water systems

There are certain water systems that are activated by amotion sensor. They are often used for cat repellent, but also for dog repellent.

In some cases, these systems work very well in the beginning. Unfortunately, they often prove useless if the unwanted animals have seen through the trick and a habituation effect occurs. After that, thebeds in your garden are no longer safe.

In contrast to ultrasonic animal repeller devices, the installation is also complicated and relatively expensive. 


With odors that are unpleasant for dogs, you can keep the four-legged friends away from your own property in some cases. These agents are usually offered in the form of sprays or granules.

Although this type of dog scare is not harmful to animals, if the chemicals seep into the soil of the garden, it can cause damage to plants. After a rainfall, the funds also have to be reapplied – a big disadvantage for those who hope for permanent dog protection. 

IREPELL® – gentle on animals and the neighbourhood

Despite all the possibilities that exist to repel dogs, some are more and less reliable against uninvited guests who dig around the garden or leave piles in thebeds.IREPELL® has been developed as an effective solution to help garden owners 

Protect property damage, health risks or potential hazardous situations caused by aggressive dogs – discreet, animal-friendly, and chemical-free. 

Since the frequency is not perceptible to people, peace in the neighbourhood remains assured. The device is not only able to drive away dogs in an animal-friendly way, but has a total of 16 different modes for different animal species, which you can select yourself via the app.

IREPELL ® is extremely effective against dogs, but also against a wide range of pests such as rats or ticks, ants, mosquitoes, moths and cockroaches as well as mice. Even larger animals that can roam in gardens are successfully repelled. These include, for example, raccoons, stray cats or martens. In addition to the ultrasonic predator sound and the infrared motion detector, IREPELL ® also offers a flashlight that drives away certain animal species with bright strobe light.

IREPELL® can be connected to the socket as well as to a powerful battery, so that the device can also be used on the go. In the future, you can not only enjoy the peace and quiet in your own garden, but also enjoy barbecue parties and picnics stress-free. 


Is ultrasound against dogs allowed?

Yes, ultrasound devices against dogs are allowed in most countries, provided that they do not have any harmful effects on the animals and are used within the legal regulations. However, it is advisable to check local regulations and animal welfare laws to ensure that the use of such devices is legal and ethical.

How do dogs respond to ultrasound?

Dogs react differently to ultrasound. Most dogs find the high frequencies unpleasant and therefore avoid the areas where ultrasound equipment is activated. However, some dogs may be more sensitive to these sounds, while others may be less impressed. Efficacy often depends on the individual sensitivity of the dog and the frequency of the ultrasound machine.

Is ultrasound uncomfortable for dogs?

Yes, ultrasound is usually uncomfortable for dogs. The high frequencies are outside the human hearing range, but are clearly audible and unpleasant for dogs. These sounds can cause stress or discomfort, which is why dogs avoid the areas where ultrasound equipment is installed.
