What kind of rodents do you have in your part of the world that they damage your _vehicles_??
Sadly, it turns out that rodents really like to eat that kind of insulation. So if you have a car made after ~2000, you need to keep pests away from wherever you store it.

https://en.wikipedia.org/wiki/Beech_marten#Car_damage:
“Since the mid-1970s, the beech marten has been known to occasionally cause damage to cars. Cars attacked by martens typically have cut tubes and cables. A beech marten can slice through the cables of a starter motor with just one bite. The reason for this is not fully known, as the damaged items are not eaten. There is, however, a seasonal peak in marten attacks on cars in spring, when young martens explore their surroundings more often and have yet to learn which items in their habitat are edible or not.[29] The fishoil often contained in the cables of cars from Japan may contribute to this”
It's weirdly common(ish) problem.
