Poison sumac plants can be pulled from the ground manually, but this method only works when the roots, leaves and vines are removed.

An herbicide can be applied one of two ways to the sumac plant. The first method is to wipe the leaves of the plant with herbicide. The second method involves using a sprayer. A certain amount of herbicide is placed into the sprayer and then sprayed directly onto the plant. A shield on the sprayer helps avoid accidentally spraying nearby plants.
