What kind of animal could be living in the suspended ceiling?

If you hear strange noises from the ceiling, it may be a stone marten, mouse or rat. An ultrasonic rodent repeller can be an effective solution. We recommend Vadalarm Smart Mono or Vadalarm Rodent Repeller.

How can I tell whether there is a marten or a mouse in the attic?

Martens leave noticeably larger droppings, mark their territory with secretions from their scent glands, and in some cases animal remains may also be found.

How many square meters can a rodent repeller cover?

This depends on the power of the device and the characteristics of the environment. In open areas, a single repeller can cover several hundred square meters, while indoors, in segmented or divided spaces, a smaller effective area should be expected. With higher-power ultrasonic wildlife repellers (such as the Vadalarm Smart Pro, Duo, Tripla and Hexa models), coverage of several hectares is also possible.

How do ultrasonic insect repellers work?

Based on our experience, unfortunately they do not work effectively. Ultrasonic insect repellers lack strong scientific support, as insects primarily rely on vision for orientation and do not possess well-developed hearing. As a result, they generally do not have sensory organs capable of detecting ultrasonic sound.

What can I do against martens nesting in the engine compartment?

Many people swear by PET bottles that crackle due to thermal expansion, however it must be acknowledged that this method is rather inconvenient and its effectiveness is questionable. The main problem with martens and rodents nesting in car engine compartments is that the vehicle’s bodywork and engine bay sound insulation—especially in modern cars—absorb the ultrasonic sound used for deterrence. Therefore, if your car’s engine compartment is very crowded, it is recommended to place a Vadalarm ultrasonic rodent repeller in front of the vehicle instead. If there is more space in the engine compartment, Vadalarm rodent repellers can safely be used there with the automotive accessory kit.

I found footprints around my car in the morning. How can I tell which animal it was? Could it be a marten?

Marten droppings are larger and darker in color compared to mouse droppings. A strong, pungent urine smell characteristic of martens can also help with identification.

We will not stop innovating during the crisis

Tóth Miklós

As autumn arrives and inflation peaks, everyone is increasingly faced with tough financial decisions, and businesses are no exception. But in such a situation, it's important to think not only about what costs we can cut back on, but also what is most important that we certainly won't.

As you have hopefully read many times, at Vadalarm, continuous improvement and development is in our blood. It has got us this far and we firmly believe it will take us much further.

And that is something we will certainly not let go of in the period ahead, no matter how big the crisis we face. You may be familiar with the TV series MacGyver (THE ORIGINAL 1985), whose protagonist even used a matchstick to cut his way out of tight situations. That's sort of how we see ourselves, and how we think all development companies should operate: in a bad economy, you have to pull engineering ingenuity out of the drawer and keep moving forward at the same pace. Because if you think about it, the crisis we're in right now can be solved by increasing efficiency. Less gas to heat the same buildings as last year.)

It's all about efficiency and ingenuity. And these are the things that mean continuous improvement for us. And our basic principle is that we will not give up on this - innovation - even in a crisis. We plan to COME SOON WITH A COMPLETE INNOVATION, which many of our customers have been waiting for for a very long time (some of them ordered it from a photo without asking how much it would cost).

Have you thought about what - if it breaks, if it rips - you won't let go of?
