Do moth balls repel snakes?

Moth balls do not normally repel snakes, notes the National Pesticide Information Center. Snakes did not hesitate to cross over moth balls in a study performed by the University of Nebraska.

Because moth balls do not repel snakes, and most purchased snake repellent powders are made from crushed moth balls, homeowners have to use other techniques to get rid of snakes. Some techniques that are effective at getting rid of snakes include physically removing the snake from your property, using a snake trap and securing places, such as holes and gaps along the home's foundation, where a snake could enter the home.
