Try to park away from areas where mice are active, such as garbage dumps, ditches, or grassy areas. Regularly inspect and clean the engine to check for signs of mouse activity and ensure the engine compartment remains clean. Placing rodent repellent bags or mothballs in hidden spots within the engine compartment can also be somewhat effective.
I drive a ten-year-old car, and the engine compartment is always infested with mice, which drives me crazy. Later, I realized the key is prevention: clean out any debris in the engine compartment before parking, and don’t leave any food crumbs behind, as mice will sniff them out and crawl in. I also bought an ultrasonic rodent repellent and hung it in the engine compartment—it works pretty well and isn’t expensive. Regularly cleaning the surroundings of the car is also important, like trimming bushes and emptying trash bins to reduce hiding spots for mice. Extra caution is needed in winter since the engine compartment stays warm after parking, making it an ideal cozy nest for mice. Once, I sprinkled some cat fur in the compartment—I heard the scent scares them off, and it worked somewhat. In short, developing good habits can save you a lot of trouble. If all else fails, it’s best to visit a repair shop.
I've encountered this issue too, and the risks of mice entering the engine compartment are significant. They can chew through wiring and hoses, leading to short circuits or oil leaks, and in severe cases, even cause fires. So whenever I find bite marks or droppings in the engine bay, I take immediate action. First, avoid parking near garbage piles or grassy areas—it's best to park in a garage or on hard surfaces. Regularly inspect the engine compartment with a small flashlight to check the hidden corners. If the wiring gets chewed through, the repair costs can be steep—I once spent hundreds replacing a wiring harness. I recommend using rodent repellent spray on the compartment walls; there are specialized products available on the market. In the long run, maintaining cleanliness around your parking area to prevent mice from breeding is the most crucial step.
As someone who loves DIY and can't resist tinkering, I've tried many methods to repel mice. A simple one is using peppermint oil: just drip a few drops on a cloth and place it in the engine compartment—mice hate the smell. Alternatively, hanging a small bag of mothballs can also be effective. I also learned a trick from a friend: stuffing cat fur into the gaps of the engine compartment. When cleaning, spray the interior walls with soapy water to remove odors and deter mice. Park in open areas, away from bushes. These natural methods save time and money and can generally reduce mouse invasions. Consistently checking once a week yields even better results.
