How to Deal with Mice Entering the Engine Compartment?

[DiClara]

You can place strong-smelling items such as mothballs or cooling ointment in the engine compartment to repel mice. Mice may chew on the wiring inside the engine compartment, causing damage to the electrical system. It is advisable to visit a repair facility to inspect the wiring and perform maintenance on the circuits.

I also encountered a mouse getting into the engine compartment last time, which was really annoying. I suggest first putting on gloves to open the hood and inspect, then gently shoo away or remove the mouse, being careful not to get bitten. Next, carefully check for any chewed wires or debris left behind. After cleaning, spray some rodent repellent or place some peppermint oil, as mice hate the smell. For prevention, choose clean parking spots away from trash bins or grassy areas—preferably open spaces—and regularly clean out any debris or food scraps in the compartment. Also, pay attention to cleaning the corners of the compartment during car washes to keep it dry and reduce the warm environment that attracts mice. This approach is both safe and simple, preventing potential short circuits and bigger issues. After all, mice carry germs and pose a safety hazard. I haven’t had any recurrence since handling it this way.
