What Do They Eat?
Opossums are omnivores who eat primarily animal matter such as insects, earthworms, small mammals, snakes, birds, fruits and vegetables.

Why Do We Need Them?
Opossums are extremely beneficial to the environment. They eat a variety of critters considered pests or vermin by clearing your yard of roaches, mice, and rats. In one season, an opossum can consume about 5,000 ticks, helping minimize tick-borne diseases such as Lyme disease. They are also known to eat carrion, which minimizes disease in the environment.
