Question: are mothballs toxic to skunks?
Answer: It may seem ironic, but skunks hate certain odors (as if they have room to judge). Citrus, ammonia, mothballs and predator urine (dog, coyote, etc) are three smells that can scare off skunks. If you use mothballs or ammonia-soaked cotton balls, be sure to keep them far away from children.
