Product advantage: Instead of cumbersome wiring, this device can be used immediately in all conceivable locations without connection. The integrated interval switch of approximately 60 seconds prevents martens from getting accustomed to the sounds. Martens are nocturnal animals and flexible in their feeding habits. Houses, barns in cities and villages, as well as warm places like garages or motorcycle rooms are among the preferred habitats of martens, where they cause significant damage. If a marten makes its home in the attic, night quickly turns into day; the rodents scratch and rummage through everything that is not securely anchored. Flower pots are emptied and overturned, and even chickens are not safe. Especially in cities, where houses are built closely together and there are few hiding places for martens, they often choose motorcycle rooms as warm resting spots. Martens often cause considerable damage to cars by gnawing on fuel, brake, hydraulic lines, or ignition cables. A marten leaves scent traces, which other martens react to aggressively, leading them to gnaw on cables and lines. The problems of chewed cables often occur during relocations to another marten territory or at territory boundaries. The mating season begins at the end of June. Therefore, territorial fights peak in May; male martens are then the most aggressive.
