How a Mouse Ate My Car

Our world is full of wonderful furry creatures. They just need to stay the heck away from our vehicles already.

I love animals: We have two cats and two dogs—and sometimes more when we foster animals for rescue organizations. I also love cars. These two passions cohabit my personality just fine, but a recent event reminded me that in the real world, vehicles and animals don’t get along so well—and that the consequences of their interactions can be pricey.

No, I didn’t hit a deer, thankfully. That’s the usual story when it comes to critter woes, especially in fall—mating season. The deer can get a bit distracted, you know. State Farm has studied deer-car collisions for 15 years, and its latest study puts the national average cost per claim at $4,179. Ouch! The insurance giant also calculates the likelihood of hitting Bambi on a state-by-state basis. Live in West Virginia? You had a 1 in 43 chance of hitting a deer in 2017. In Hawaii, it was only 1 in 6,823. (Deer in Hawaii? Yes, they were introduced.)

Hitting a deer with your car may damage the vehicle but is unlikely to injure you. But swerving to miss a deer or a dog or any other animal and instead colliding with a guardrail, tree or—the worst—another car is an entirely different story. If an animal does appear out of nowhere in front of you, brake as hard as you safely can, but don’t swerve, say safety experts. It pains me to say this, but just hit the darn thing if you can’t stop in time.

The rodent exclusion. Beyond your safety, there’s also a pocketbook issue for that guidance. If your car is damaged by collision with an animal, that’s a claim on your comprehensive coverage, which is meant to cover things that can’t be blamed on your driving (such as fire, falling trees and theft). But if you damage your car while avoiding an animal, it would count against your collision insurance. Collision claims are much more likely to lead to higher insurance rates than comprehensive claims. If you damaged property or hurt someone else in the process, that would trigger your liability insurance, and now things can really get ugly.

My wildlife woe—which wasn’t covered by insurance and cost me about $6,000—was caused by a much, much smaller animal that would not have made so much as a thump had I run over it. A mouse (or some other tiny creature with big, nasty, pointy teeth) chewed on the wires in the hybrid battery pack of my wife’s Toyota Highlander.

Mickey (or Minnie) isn’t solely to blame; I am as well, for having let a water leak into the passenger compartment—where the battery is located—go unrepaired. During an exceptionally heavy rain, water met gnawed cables, and the car’s hybrid system took deep umbrage. Unfortunately (I guess), the short didn’t cause a fire, because that might have been covered by insurance. In our case, we had no coverage because of my insurance carrier’s “rodent exclusion.” (My wife: “Can we tell them it was raccoons?”)

Not all policies have this limitation to their comprehensive coverage, says Penny Gusner, consumer analyst for Insurance.com. If you think you’re at risk for varmint invasion, it pays to check because the coverages and rules vary from company to company and state to state.

Quiz: Does Car Insurance Cover That?

How can you do your own rodent exclusion—that is, keep rodents out of your car? Keeping the interior clean is one of the anti-vermin tips recommended by rodent-control company Victor Pest (you might know them from their iconic snap traps). We definitely failed to do that with the Highlander, which carried my kids during the Cheerios-and-Chex-Mix phase of their lives. Another tip is to let your cat roam the garage where the car is parked—if you have a cat. Victor Pest also sells scented products it claims mice will avoid.

Rodents don’t always head for the interior of your car. Air intakes for both the passenger compartment and the engine can be another vector. I’ve seen people improvise barriers made out of metal hardware cloth for the engine air intake. If you try that, make sure it doesn’t get plugged with leaves or other debris that could reduce airflow.
