Does this help with copperheads?

This product is recommended for use to repel rattlesnakes (Genus Crotalus) and checkered garter snakes (Thamnophic marcianus). While the product might deter other types of snakes as well, it is not expected to consistently repel snakes of the following types: corn snakes and other rat snakes (Genus Elaphe); and “moccasin” snakes such as cottonmouths and copperheads (Genus Agkistrodon).
