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.

Why you should put your Vadalarm Smart products on Wifi?

Tóth Miklós

As you probably know, the Vadalarm Smart family, renewed this spring, has the unique ability to be connected to your home's Wi-Fi and be checked even while you're on holiday. But many people don't know that this is also very important for servicing and troubleshooting. Here's why this feature is useful for you too, with real-life examples.

The most important thing is the charging

You could say that the solar panel and the power supply are the overheads of Vadalarm Smart products, the basis of their operation. Because without it, there is nothing. We are often confronted with cases where customers indicate that their products are not charging enough. This is one of the most common sources of problems, which fortunately we can check remotely (provided the device is connected to Wifi).

In such cases, the service naturally begins with our customer service team interviewing the customer about the outsourcing and then our IT team verifying the data submitted by the device. We see nice diagrams like the one in the picture below.

Our first diagram shows an ideally operated Vadalarm Smart Mono. In the upper half of the graph, you can see that the battery is steadily dipping, which our customer charges every 11 days or so. On the lower half of the graph, we can see the variations in temperature between night and day.

The second is a Vadalarm Smart Pro used in a sunny location, which gets about twice as much sunlight as it needs every day, and its battery is constantly charged.

And the third figure shows a graph of a product placed in a sunlight deprived area. In this case you can see that the battery is getting a charge every day, but not nearly enough. In such cases, our customer service clearly recommends relocating the product.

The main lesson

If we had to sum up the main message of the article in one sentence: put it on Wi-Fi (if you can). This will save you a lot of hassle and even unnecessary postage (and the cost of it). And by sending data to our servers 24 hours a day (currently around 100 devices per second), you are helping to make our devices even better in the future. Thank you for this.
