Why do martens bite cables?
Martens seek out engine compartments because it is warm and dry here - an ideal place to sleep. Sometimes they take some insulation with them to pad other sleeping quarters or their nest. It is not clear why martens nibble on cables. One theory is that they use their teeth to explore their surroundings and taste everything while doing so. Another theory is that they become aggressive when they scent another marten that has slept in the same engine compartment. They then bite furiously and cause great damage. This happens especially during the mating season.

High-voltage devices against martens
The high-voltage devices are permanently installed in the engine compartment and give the marten an electric shock if it steps on the line. It works like a pasture fence that is electrified, preventing horses and cows from escaping. When the engine is switched on and the bonnet is open, high-quality devices switch off automatically. In addition, the devices consume negligibly little power, so that it is almost impossible to discharge the battery.
Numerous buyers confirm the good effect of high-quality devices and speak of very positive experiences. Some cheap products also get positive customer reviews.
