How to Deal with Mice Entering the Engine Compartment?

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.

As someone who often tinkers with cars, I've found that mice enter the engine compartment mainly for warmth or to search for food. When dealing with them, don't rush to act recklessly. First, turn off the engine and wait for it to cool down. Put on protective gear, open the hood, and remove the mice—you can use long pliers to gently extract them or wait for them to run away on their own. Next, inspect all wire connections for damage, especially areas where the insulation has been chewed, and promptly wrap them with tape to prevent short circuits. Clean the compartment, spray alcohol for disinfection, and then place electronic rodent repellent tablets in the corners. For prevention, install mesh covers over air intakes and park away from areas where rodents are commonly found. I also recommend performing seasonal maintenance on the compartment to keep it clean. This approach saves money, protects the vehicle, and can essentially eliminate rodent problems, reducing unexpected repair costs.

From a safety perspective, having rats enter the engine compartment poses significant risks, so I always handle the situation with extra caution. First, I open the hood to ventilate for ten minutes, then wear double gloves and a mask when dealing with the rodents, as they may carry viruses. After gently sweeping or removing debris, I thoroughly clean any stains with water and disinfectant. I carefully inspect for any chewed components, and if found, I immediately repair them with temporary materials or seek professional help. For prevention, avoid leaving food in the car and place mothballs or chili powder around the compartment to deter rodents. Park on hard surfaces, avoiding areas near bushes, and conduct regular inspections. These measures protect family health and ensure vehicle safety, as neglecting a rat infestation can disrupt daily use.
