Gross, but not as bad as what can happen in more modern cars: hundreds of dollars in repairs. While the rodent’s nest could quickly become a fire hazard in a running car, it’s their teeth that do the most damage. The double whammy of cars sitting too long mixed with a lack of food from shuttered restaurants are driving the rodents to seek out parked cars as not just shelter but as a potential food sources. The little guys are chowing down on the wiring of some cars, the Free Press explains:

A class-action lawsuit was filed in 2016 in California against Toyota claiming the company should cover — under warranty — damage from rodents chewing through insulation for wiring that is now soy-based versus petroleum-based.


But even owners of cars with petroleum-based wiring insulation can find their electrical system chewed to bits, as all wires make for great chewing for critters with constantly growing teeth. Replacing a whole wiring harness is not cheap. One Michigan mechanic told the Freep his independent shop averages around $400 to $600 for the repair.

The best way to avoid an infestation is to drive your vehicles, but that’s not always an option. If you’re worried about leaving your ride laying around, the Freep has some solid tips for keeping your car vermin free. Hopefully, these tips aren’t too late to save some cars:

Here are some other suggestions from the experts:

Reminder: Do not use a rat or mice poison for outdoor vermin as local birds or prey or cats might accidentally ingest the poison.
