Rodents chewing through vehicle wires and cables causes thousands in damages annually. Rats, mice, squirrels and other pests are drawn to the soy-based coating on modern wiring. Once they start gnawing, expensive electrical problems follow. Here’s how to prevent rodents from wreaking havoc under your car hood.

Why Rodents Chew Car Wires

The plastic coating on vehicle wires today often contains soy or other organic compounds that smell and taste desirable to rodents. They chew right through the thin plastic to access the flavors within.

Once wiring is exposed, hazardous shorts and electrical failures can result. Chewed wires also provide access to shelter inside engine compartments and vehicle cabins for rodents.

FAQs About Rodents and Cars

Here are answers to some frequent questions about deterring automotive rodent problems:

Where do rodents enter cars? Through wheel wells, undercarriage gaps, openings under the hood, vents, sunroof drains, and any other small openings. Mice can squeeze through amazingly small cracks.

What smells keep mice out of cars? Mothballs and ammonia-based cleaners have strong odors that may deter mice temporarily. But sealing access points is more effective.

Is peanut butter good for catching mice in cars? Setting small sticky traps or snap traps baited with peanut butter can help remove mice inside car cabins when parked. But exclusion is still needed.

What damage do squirrels cause to cars? Squirrels love chewing through insulation for nesting material. They cause extensive damage to wires, hoses and other vehicles parts in the process. Their large teeth can chew through most coatings.

How do you keep rats out of car engines? Seal all possible access points into the engine bay. Place traps outside to intercept curious wanderers. Homeowners may need to also clean up debris piles and outdoor food that attracts rats to the parking area.

Do mothballs work to repel rodents from cars? The strong smell of mothballs provides limited, temporary repellency against rodents around vehicles. Works best if mothballs are hung up out of reach of pets. Reapply the smelly flakes regularly. But it’s better to exclude rodents fully with repairs.
