Poison sumac (Toxicodendron vernix) is a large shrub or small tree that reaches mature heights of up to 20 feet, but usually tops out at 5 or 6 feet. The stems are red and the leaves are arranged in 7 to 13 pairs of glossy green leaflets, often with pale green undersides.
Poison sumac trees grow in wet, swampy or boggy areas or along shorelines. The plant is most common in the Great Lakes and coastal plains, but it is sometimes found as far west as Texas.

Herbicides containing glyphosate are an effective means of control. Use the product strictly according to the directions on the label, and keep in mind that glyphosate is non-selective and will kill any plant it touches.
Alternatively, you can cut the plants to a height of about 6 inches (15 cm.), then apply the weed killer to the cut stems. Use pruning shears, not a weed trimmer or mower, to avoid releasing irritating plant parts into the air.
