Rodent damage like this is not because the wires taste good

Myth: Rodents Like The Taste Of Wire Coating

You have probably heard rumors that car manufacturers use soy and other organic products when making car wires, which is why rodents chew on the internal wiring of cars. This could not be further from the truth. Unfortunately, rodents chew on things for a far more practical reason: they need to keep their teeth trimmed. Chewing on car wires gets the spotlight because it's an inconvenience to drivers and damages the vehicle. Rodents will chew on just about anything, including plastic, to keep their teeth trimmed.

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

This is not completely false; there is research to support the belief that some mice might be able to detect magnetic fields. Sadly, this is not the reason they decide to nest inside the compartments of an engine and it's not likely we'll find the answer anytime soon. Mice like to make a home out of dark spaces with nooks and crannies, which makes an engine bay in the winter look awfully homey. Vehicles not only offer protection but they have lots of things for mice to nibble on to keep their teeth trimmed.

Fact: Rodents' Teeth Keep Growing

As we keep mentioning, rodents need to keep their teeth trimmed. This is because their teeth do not stop growing. If rodents like squirrels and mice do not trim their teeth they will grow so long they will not be able to eat. There is a theory that rodents seem drawn to the wiring of vehicles because they somewhat resemble the natural growth of shrubs, vines, and various other greenery found in nature.

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

Try This: Move Vehicles Regularly

Typically rodents seem to prefer vehicles that are stationary for long periods of time. The easiest way to avoid dealing with rodents grooming their teeth on your wiring is to move your vehicle often. This is not to say a rodent will not call your daily driver home, but it is far less likely. When you start your car, the engine should scare away any visitors that may have stayed in your vehicle overnight. We encourage you to drive your vehicle often and move it from one spot to another or park in your garage. If you struggle with a rodent issue, it's best to call in a professional for advice.
