Marten appreciate protected shelters like warm engine compartments to hide from predators. Unfortunately, they damage cables and hoses in the vehicle, which can lead to costly repairs or even total loss of the vehicle. Therefore, you should protect your vehicle from the intrusion of these small animals. Efficient and environmentally friendly: Simply park your vehicle with the wheels located in the engine compartment on the marten-repellent mat. The animals avoid the plastic grid as it is uncomfortable for their sensitive paws to walk on. This very safe deterrent method is also environmentally friendly, as it does not harm the animal, no chemicals are released into the environment, and no batteries are required.
