Poison ivy loves to wreak havoc and make you itch. And because it packs a complex root system and a rash-inducing oil, it can be a pain to get rid of. Thankfully, there’s a method for controlling the madness. Survey problematic areas monthly during growing season (May through November) and look for new poisonous plants that might have appeared.
You’ve probably heard, “Leaves of three, let it be.” But there are a ton of three-leaved plants out there! Here are some handier ways to identify poison ivy:
Watch for three leaves with smooth sides and pointy tips. There are two smaller leaves beside the longer middle leaf. Leaf lengths range from 1/4 of an inch to 2 inches.
Poison ivy can appear as ground cover (4–10 inches), upright bushes or shrubs (up to 4 feet), and as vines that climb trees.
Each group of three leaflets grows on its own thorn-less stem and alternates arrangement. These stems all connect to the main vine, which is covered in hair.
“Hairy vine, no friend of mine!”
Leaves emerge a reddish color, but will start to turn green as the spring progresses.
Leaves are typically green, and the plant may have clusters of light green or cream-colored berries.
Leaves change from green to shades of red, orange, and yellow.
Poison ivy loses its leaves in the winter. But beware of the leafless vines, as they can still produce rash-causing oil.
North America, primarily in the Midwest and eastern United States. Poison ivy typically doesn’t reside in the western United States, desert areas, or at high altitudes.
Poison ivy annually invades yards because of the “edge effect.” That’s when seasonal weather patterns cause wooded areas at the fringes of yards to dry out, creating a perfect habitat for poison ivy.
The dark floor of wooded areas frequently houses creeping, crawling poison ivy.
Poison ivy loves to play hide and seek and commonly imitates tree branches. Sorry poison ivy, you’re not fooling us.
Poison ivy sometimes makes a home for itself on or around dead tree stumps.
While not typical, poison ivy can even develop into a shrub, usually in a sunny location.

To control thick poison ivy vines, cut them to 3–4 feet and then spray the leaves with Roundup® Poison Ivy Plus Tough Brush Killer. That’ll do the trick.

Proper disposal is the final step in getting rid of this noxious weed. Make sure to wear disposable gloves and clothes that cover your skin completely. Place the remains into a tightly sealed garbage bag, and then clean your tools and clothes with hot, soapy water.
Poison ivy’s secret weapon, urushiol, is both a toxin and an irritant. Contact causes a red, itchy rash that can take 10 days or longer to heal. Also, know that it covers not only the leaves, but the entire plant. So even when the leaves are gone, the urushiol isn’t.
“Even when the leaves are gone, the urushiol isn’t.”
