Said It Here

Why are animals chewing holes in my car plastic and gas tank?

Rodents and wildlife chew on vehicle parts like plastic wheel covers and gas tanks because modern engine components use soy-based wiring and materials that attract pests. This leaves vehicle owners dealing with expensive physical damage and rendered equipment that cannot be safely used until repaired.
