These pests love the warmth of cars and can quickly sneak inside through minor cracks and crevices. Once they are in, they can be hard to deter. To make matters worse, they stink.

Besides regular cleaning, you can also maintain practices that will keep your car clean for longer. Avoid eating or spilling food inside your vehicle. Take all trash out of your car and put it in a trash bin.
