Why Do Rodents Chew Car Wires?

The idea of rodents finding a delicacy in car electrical wires is quite bizarre. But rodents find excitement in outrageous things. 

  • The shape of the electrical wires is quite enticing because it resembles the shrubs they eat in the bushes. Hence, they can confuse the wires for their food source. 
  • Rodents are cunning and will gnaw at anything within their reach. So when their nest is near the car electricals, chewing the wires will be a favorite undertaking. 
  • There are wires made from vegetative matter, so rats will find them palatable. In addition, they will gnaw at the rubber coverings of wires to sharpen/trim the rodent teeth. 

What Types of Rodents Chew Car Wiring?

How to Prevent Rodents from Chewing on Your Car Wires

Lay Traps Around Your Vehicle

Traps are one way to fix the problem, especially when dealing with a large-scale rodent infestation.

 The good thing is that you can use many types of traps. They include 

  • Catch-and-release bait
  • Snap traps
  • Electronic traps. 

Also, undertake the following precautions to improve the chance of trapping more rodents. 

  • Set enticing bait. Rats will eat anything, but there are foods that they like more than others. For instance, nuts are more attractive than other foods, so you should consider using them/their products. 
  • Avoid touching bait with your hands. You will infuse human smell into the food, which may put off the rodents. 
  • Try out different traps to optimize the chances of catching the rodents.
  • Make sure to keep checking the traps. This step will help you to replenish the bait and remove the caught rodents continuously. 

Use Rodent Deterrents

Rodents are highly sensitive to smells, which helps them make up for their poor eyesight. So, using a deterrent can be exemplary in keeping them at bay. 

Peppermint oil is among the best repellents to apply around your car electricals. It is not a pollutant, and its strong smell will dissuade the rats from coming near the wires. 

An alternative is to use special tape, essentially laced with capsaicin, a chili pepper repellent. 

Block Entrances to Your Vehicle

The car’s hood and vent provide a perfect avenue for rodents to enter the vehicle. 

Blocking it with mesh wiring prevents the issue. Also, rats and mice love secluded areas such as your garage. 

Comprehensive coverage of all possible entry points will do the trick in keeping the rodents away. 

Keep Your Car Hood Up

The warm environment in the hood is an excellent habitat for rodents, meaning you’re most likely to find their nest in this environment.

 Consider having the hood up to expose the interior to discourage rodents from burrowing and nesting. 

Alternatively, install lights inside the hood area. 

Clear Hiding Places Near the Car

Cut all the shrubs around the garage as they are harboring grounds for rodents. 

Also, clutter in the garage can be a perfect rat breeding ground. So clear everything around to eliminate the hiding places. 

Regularly Run Your Vehicle

There is no way rats will stay inside the car engine chamber when it’s running because of the high temperatures. Make sure you don’t park your car for too long. 

Avoid Leaving Food in the Car

Your attempts to deter rats will be futile if you leave human and pet food all over the car. 

 A clever solution is always removing everything you’ve been eating in the car. Again, make sure to empty your car’s food waste bin.

Rodent damage

You can outright know when rodents have been chewing your car electrical wires. Check out for the presence of the following signs: 

  • Scratches or gnaw marks on the wires mean there’s a rat infestation. 
  • If you find rodent droppings in the car, this is also a telling sign that rodents are onboard. 
  • The main culprits of a rat attack will be the non-metallic components of the car. Hence, rodents are aboard if you see marks and holes on the plastics, in addition to the above signs. 
  • The car will develop issues while starting, especially if the rodents eat the critical components. The lights can also be affected if the mice gnaw on the electricals connecting to the battery. 
  • Finally, there may be an infestation if there’s a foul smell, tiny bits of paper, and wire cover chippings. You should immediately act on these issues, as rats are also a significant health hazard problem.
