You’ve probably heard of rats looting around in the garbage or inhabiting sewers. But you may not have heard of rats finding their way into car engines. While it might seem hard to believe, it’s actually a reality many have faced. Though it is surely an unpleasant thought, and even more unpleasant if you find yourself faced with it, there are steps you can follow for managing and getting rid of rats in car engines.
Why are rats attracted to cars?
There is some speculation that there are more rats seeking refuge under car hoods and in engines because of an increase in plant-based biodegradable material that make those materials seem like sources of food; additionally, some claim (even bringing about class-action lawsuits to various manufacturers like Honda and Toyota) that new, soy-based wiring rat her than petroleum-based wiring attracts the pesky rodents.
In addition to these speculations, there is the usual reason for why a rat would find itself in a car engine: They are seeking shelter. Many rats look for dark, enclosed areas when finding places to take shelter, both of which are offered under the hood of a car. And in the winter, they’ll likely be looking for somewhere warm. More often than not, rats are targeting cars parked in rat infested areas, areas they travel in or cars that are rarely used - such as cars in storage for long periods of time. For this reason, certain measures should be taken specifically to protect cars in areas that rats are known to be.
How to get rid of rats in car engines

Also, consider a mask so you don’t breathe in any contaminated rat byproducts. While the engine compartment is perhaps the most common place to find a stowaway rat, you should also check:

- The trunk
- Underneath the hood
If you suspect to have a rat infestation in your car, it’s crucial to have a mechanic properly inspect all areas carefully.
What not to do
If you find rat droppings or urine, don’t vacuum or power wash. These methods could distribute germs and bacteria in the air.

This should then be sprayed on all the affected areas, and then left to sit for at least five minutes to properly disinfect the materials. You can then clean up the droppings or other byproducts with a paper towel, keeping your gloves on. This should all be immediately discarded, and covered with additional disinfectant before sealing the bag tightly. If you are cleaning out the engine compartment, the CDC recommends for you to disconnect the battery while you are cleaning and then only reconnect it after everything has dried.
