How to Prevent
During colder times, the car is a most unpleasant place for something like this to happen. Another interesting way to deter these critters is to add “bad-tasting rubs” to the wires, so they won’t find it enticing to have a nibble. You can use things like bitter apple spray, which has a bad taste but is still safe for the squirrels.
Advice from the Mechanic
Before you take any measures in preventing these animals from lodging in your car, it is best to get advice from your mechanic or veterinarian as to which step is best so no one gets hurt. You can keep the squirrels away, keep your property safe, while still not causing damage to the wildlife.
