Because raccoons are scavengers, they play an important role in cleaning up carrion. They also dine on other species we consider pests, including snakes, frogs, lizards, and rats. Raccoons don't exclusively eat meat, either. Like skunks, raccoons are omnivores that also feast on berries and nuts, which in turn helps plants spread seeds. They may be known for making messes, but they do a good job of cleaning things up elsewhere.
