2. What types of marten repellent are there?

marten repellent test

Pay attention to the indicators in your car if you fear marten damage.

there are three different types of marten repellent devices. All three have both advantages and disadvantages. The basic distinction lies in the way the marten is to be disturbed. The types of marten repellent work with ultrasound or electric shocks. some marten repellent models have an additional flashing light function to scare off martens.

The marten repellent with ultrasound works, as the name suggests, with ultrasound. The sound travels in a frequency range that cannot be heard by humans. A marten, on the other hand, hears these frequencies clearly and finds them extremely unpleasant and is therefore kept away from the car.

The marten protection with high voltage drives away the animals, similar to the cow grazing system with electric shocks. When touching the contact plates, the marten receives an electric shock and then leaves the area.

A very effective way to repel martens is to use a device that combines ultrasound and electric shocks. these models include an electronic control system, several metal plates and an ultrasonic component.

some marderschrecks are also equipped with a motion detector or a circuit diagram.

  • Frequency range that cannot be heard by humans, martens find this very unpleasant and drive them away.
  • High quality devices change stands the frequency range, so that the animals can not get used to a certain frequency.
  • In the case of cheap products, some frequency ranges can be heard by people, especially babies and small children, which in extreme cases can lead to damage to the hearing.
  • Marderschreck is suitable also for the house.
  • Consists of several contact plate and a control unit.
  • In the engine compartment the contact plates are attached exactly at the places which are to be protected.
  • As soon as the marten touches the contact plates, it receives an electric shock.
  • When the engine is switched off, the marten repellent activates automatically, provided you have chosen a high quality device.
  • Offers protection from martens through ultrasound and high voltage.
  • Consists of an ultrasonic component and an electronic control system and metal plates.
  • Contact plates are attached to the places that are to be protected.
  • The entire system aktivates as soon as the engine is switched off. As soon as the engine is switched on, the system deactivates itself again.
  • If, despite ultrasound, the marten does get in should the marten get into the engine compartment, an electric shock will drive the marten away.
  • With the combination of high voltage and ultrasound, this variant offers almost 100 percent protection against marten damage.

To make your purchase decision easier, we have listed the advantages and disadvantages of the combined version of the marten repellent with ultrasound and high voltage:


  • Very effective.
  • Offers double security through marderschreck ultrasonic component and high voltage.
  • Automatic activation of the system as soon as the engine is switched off.
  • Almost 100 percent protection against marten damage.

3. Buying advice: what points do you need to pay attention to when buying?

In order for you to buy the most suitable marten repellent for you, we have put together a buying guide for you.

3.1. Legal regulations must be observed

marten deterrent harassment

Some products produce a very unpleasant beeping sound.

First of all, you must make sure that your device complies with the legal provisions and is approved. Especially cheap products often do not meet the standard.

If the beep of an ultrasonic device can be heard by humans, the device does not comply with the legal requirements. For neighbors and especially babies and small children, the marten repellent becomes a nuisance and they may even suffer from hearing damage.

Therefore, we strongly recommend that you buy equipment that complies with the legal requirements. Otherwise there may be legal consequences.

A marten repellent with high voltage must also comply with the CE standard. It should have a low power consumption.

3.2. Quality must be right

marten scare frequency

Your marten repellent should be able to change frequency.

The quality goes hand in hand with the legal requirements. the frequencies of a cheap marten repellent can often be heard by humans as well. The noise is not only unpleasant, it also damages the hearing.

A cheap marderschreck is also very often characterized by a non-changing frequency of the ultrasonic sound. A marten gets used to a certain frequency after a certain time, so that the device is then useless for you.

A more expensive device with constantly changing frequencies keeps the rodent away for a long time, because the animal has no chance to get used to the frequency.

3.3. How each type of marten repellent convinces

marten repellent test marten trap

Marten traps should not be used to get rid of a marten.

With the marten scare with ultrasound you drive away the marten with very high frequencies. Provided that the sounds are not perceptible to the human ear, and the device produces constantly changing frequencies, we can highly recommend this type to you. A marten repellent with ultrasound is also comparatively inexpensive.

Also the marten repellent with electroshock usually works well. Some critics and animal rights activists have the following opinion, it is cruelty to animals to attach a marten repellent with high voltage to your car. Proponents of the marten trap with electric shock counter that it is also not conducive to the healthy lifestyle of the animal, if it feeds on plastic and plastic cables. For the protection of the human being from car accidents it is also extremely important, prevent marten damage.

Attention: to catch a marten, we can not recommend to you. On the one hand, the marten will return to your car after release and on the other hand, the animal is unnecessarily tortured by marten traps, because they are very narrow and the marten has hardly any space in them.

The combined solution, in which the marten repellent is equipped with both ultrasound and high voltage, offers the best protection against marten damage, but is also the most expensive variant. Nevertheless, we advise you to use this type of combination for maximum safety.

4. Is there a marten repellent test from the stiftung warentest??

5. What questions and answers about the marten repellent are helpful?

5.1. On point – how does a marten repellent work??

The functionality of the marten scare for the car depends on the model. With an ultrasonic marten repellent sounds are emitted, which are not perceptible for humans, which are but makes martens absolutely uncomfortable, so that they look the other way.

Other marten repellent products work with electric current and emit a shock as soon as the marten enters the networked area.

5.2. How much power does a marten repellent need??

A marderschreck consumes fortunately relatively little power. The sound generator is only stimulated more strongly in pulses. This increases its current flow to approximately 130 ma. Otherwise it is far below.

connect marten repellent correctly

When installing the marderschreck is to be careful.

If you have chosen a device with ultrasound, or the combination of ultrasound and high voltage, you must when installing the device, make sure it is placed correctly.

Ultrasound behaves in its propagation similar to light. Thus, objects can create shadows that prevent the glaring sound from reaching every area. Therefore, make sure to orient your ultrasonic device so that all parts at risk can be sonicated.

As far as the electric marten repellent is concerned, it is very important to place the contact plates in the right place. Martens often climb over tires and wheel housings to where they don’t belong: in the engine compartment. we therefore recommend you to place some of the contact plates here. The electric fence should be placed in such a way that you protect car parts that are particularly vulnerable to marten damage.
