Effectively prevent marten damage: Martens may look cuddly and cute, but they can quickly cause serious problems in your home, garden or car. They gnaw through building materials and cables with ease and leave behind faeces, urine and foul-smelling food scraps. Added to this is the noise nuisance, especially if they live in the loft. Before you hire an expensive exterminator to deal with a marten problem, you should use this car marten deterrent, which uses high-frequency sounds and flashing lights to ensure a marten-free environment. Drive away martens in an animal-friendly way: The car marten repeller has an impressive range of up to 60 square metres in enclosed spaces. At 30-second intervals, the marten repeller emits high-frequency sounds that disturb the furry creatures. The sound frequency is constantly changed to prevent a habituation effect. An LED flashing light is also triggered at regular intervals. Another advantage is the built-in vibration sensor, which recognises when your car is moving and automatically switches the device off. This ensures energy-saving use of the marten repeller in the engine compartment. Flexible power supply: The marten deterrent can be used in the car as well as in the loft, garage or on the patio. In the vehicle, the compact device is powered by the car battery. For all other locations, the marten alarm only requires four standard AA batteries.
