Rodent damage like this is not because the wires taste good 

Myth: Rodents Like The Taste Of Wire Coating

You may have heard something about car makers using soy or other organic products when making car wires, and that's why rodents chew on them. However, this just isn't true. You see, rodents' chew on things to keep their teeth trimmed. The chewing on car wires gets all the attention because it's so destructive. However, rodents will also chew on plastic or anything else that's in their reach.

Myth: Car Wiring Emits An Electric/Magnetic Signal That Attracts Rodents

OK, there is evidence that some mice may be able to detect magnetic fields, but there's far less evidence that this is the reason they decide to call engine compartments home. Until we can sit down and ask a rodent for their secrets, the most likely explanation is that a car just makes a great habitat. It's typically dark with lots of nooks and crannies for a critter to hide in and stay safe. In the winter, an engine bay can offer warmth, and there's lots of stuff to gnaw on and keep their teeth trimmed.

A dark part of a car like this one is a great place for rodents to call home 

Fact: Rodents' Teeth Keep Growing

We mentioned keeping teeth trimmed above, and that's the main reason that rodents like squirrels, mice, and others need to chew on things. If they don't, their teeth will grow to the point that they wouldn't be able to eat. In fact, one theory on why rodents seem to always find the wiring harness under the hood is that it resembles the natural growth of shrubs and bushes in the wild.

Experts know what they're looking at and how best to proceed 

Try This: Move Vehicles Regularly

While we can't say that a desperate rodent won't find their way under the hood of your daily driver, it is far less likely. Imagine if you were all curled up for a nap when your couch turns out to be a massive and noisy engine. That's why we typically see damage from rodents in vehicles that are kept outside and not driven regularly. Try to drive the car regularly or at least move it from one spot to another. If you can, park in a garage. Of course, the best rodent deterrent is to call in the pros.
