Mice are attracted to cars for several reasons: Shelter: Cars provide a warm and enclosed space that offers protection from predators and the elements. Nesting material: Mice may be drawn to the soft materials within a car, such as fabric or insulation, which they can use to build nests. Food sources: Crumbs, food wrappers, or other edible items left in the car can attract mice looking for a meal. Water sources: If there are water leaks or condensation within the car, mice may be attracted to these moisture-rich areas. Taking measures to eliminate these attractants and regularly cleaning your car can help deter mice.
