What methods can be used when mice enter the engine compartment?

When mice enter the engine compartment, substances like mothballs can be used to repel them with their odor. After driving the mice away, it is necessary to inspect the vehicle's condition. If no issues are found, a protective net can be installed to cover the car's chassis. Regular cleaning of the engine is also required to prevent mice from re-entering the engine compartment. The reasons why mice are attracted to the engine compartment include: 1. The car is frequently parked near garbage dumps or trash cans; 2. The car is often parked next to walls, grassy areas, or sewage ditches; 3. There are leftover food residues near the parking spot, prompting mice to enter the engine compartment for feeding; 4. During the colder seasons of winter and spring, mice tend to seek warmth by entering the engine compartment.
Last time my car was also visited by mice, leaving debris and a strong urine smell in the engine compartment. I tried applying peppermint essential oil to the wire conduits, reapplying every three days with good results. When parking, I made sure to avoid bushes and trash bins, opting for open concrete spaces. Someone recommended an ultrasonic rodent repellent, so I bought one that plugs into the cigarette lighter and automatically emits high-frequency sound waves when driving. Placing Sichuan pepper packets in the corners of the engine compartment worked well, but I had to bring them in during rainy days to prevent mold. Now I regularly lift the hood to inspect, and each time I find traces of lingering odors near the throttle body. When cleaning, I wear gloves and wipe three times with disinfectant—otherwise, the smell can linger for months. The most crucial thing is to maintain a clean environment and avoid eating snacks in the car to prevent crumbs.
