How to get rid of poison ivy safely
Here’s how to get rid of poison ivy: cover your skin, then kill the plant at the roots. Pull or dig out small plants with every bit of root, and spray larger patches or paint freshly cut vines with a systemic herbicide such as triclopyr or glyphosate. Bag everything, wash your tools and clothes, and never burn it. Expect to treat regrowth at least once.

How do you identify poison ivy?
“Leaves of three, let it be” is a good start, but poison ivy varies a lot from yard to yard. Check several features together:
- Three leaflets per leaf, and the middle leaflet sits on a longer stalk than the two side ones.
- Leaflet edges can be smooth, wavy, lobed or coarsely toothed, even on the same plant. Leaves can be glossy or dull.
- Color changes: reddish when new in spring, green in summer, bright red-orange in fall.
- Three growth forms: a low ground cover, an upright shrub, or a climbing vine.
- Hairy vines: climbing stems are covered in dark aerial rootlets that make old vines look like fuzzy rope on tree trunks and fences.
- Berries: clusters of whitish, waxy berries in late summer and fall.
In winter, the leafless vines and stems are just as toxic. If you are unsure what you have, compare it with the plants in our weed identification guide.
Poison oak, poison sumac and harmless look-alikes
| Plant | How to tell it apart | Causes a rash? |
|---|---|---|
| Poison oak | Three leaflets with rounded, oak-like lobes, duller green and hairy on both sides; usually an upright shrub. Atlantic poison oak grows in the Southeast, Pacific poison oak on the West Coast. | Yes, same oil |
| Poison sumac | A shrub or small tree with 7 to 13 leaflets per leaf, found in wet, swampy ground. | Yes, same oil |
| Virginia creeper | Five leaflets spreading like fingers from one point; blue-black berries. | No for most people |
| Box elder seedlings | Three to seven leaflets arranged like a feather; leaves sit opposite each other on the stem. | No |
| Fragrant sumac | Three leaflets, but the middle one has no stalk; upright shrub with fuzzy red berries. | No |
Poison oak and poison sumac are controlled exactly like poison ivy, with the same precautions.
Why poison ivy is dangerous even when it’s dead
Every part of the plant (leaves, stems, roots, berries) contains urushiol, an oily resin that causes an itchy, blistering rash in most people. It is there all year, it stays active in dead plants and roots, and it clings to gloves, tool handles, shoes and pet fur for months or longer. You can get a rash from a dog that ran through the patch or from a shovel used weeks earlier, without ever touching the plant.
Never burn poison ivy: the smoke carries urushiol. Breathing it can cause serious allergic reactions in the eyes, nose, throat and lungs, which can be life-threatening. That includes burn piles of dead vines and brush with poison ivy mixed in.
What should you wear?
- Long sleeves, long pants tucked into socks, and closed shoes or boots.
- Heavy-duty disposable gloves or waterproof gloves. Cloth gloves soak up the oil.
- Safety glasses, especially when cutting vines or working overhead.
- Plastic bags and ties within reach, so you never set debris down.
How do you remove poison ivy by hand?
Hand removal works for a few plants or young seedlings and is the only option right next to vegetables or plants you can’t risk spraying.
- Water the day beforeMoist soil lets the roots slide out instead of snapping. Pieces of root left behind will resprout.
- Use the bag trickSlip a plastic bag over your gloved hand, grab the plant at the base and pull slowly. Turn the bag inside out over the plant and seal it.
- Dig out the rootsFollow the runners with a trowel or shovel and remove roots several inches deep.
- Come back every week or twoCut or pull any new shoot. Removing the leaves again and again starves the roots over time.
What kills poison ivy?
For established patches and big vines, a systemic herbicide is usually the most effective and the safest choice, because you handle the plant much less. Systemic products move from the leaves down to the roots, so they work best on plants with healthy, fully grown leaves, between late spring and early fall. Plants stressed by drought absorb less and respond poorly.
| Active ingredient | What it does | Best timing |
|---|---|---|
| Triclopyr | Selective: kills broadleaf plants and woody vines, spares lawn grasses. Often the most effective on poison ivy. Can stay active in soil for a month or more, so check the label before replanting. | After the leaves have fully expanded in spring, through summer |
| Glyphosate | Nonselective: kills grass and any plant it touches. Inactive once it reaches the soil, so you can replant sooner. | Around flowering, then any time the plant is actively growing |
| 2,4-D + dicamba + mecoprop | Three-way broadleaf weed killer for lawns; helps on young poison ivy, but expect to repeat. | Late spring to early summer |
Spray on a calm, dry day so the product does not drift onto nearby plants, and wet the leaves without drenching them. Leaves wilt and brown over the following weeks. Spray again when regrowth appears: one application rarely finishes an established patch. Read and follow the label for rates and for any pet and child re-entry time; in the US, the label is the law. Our weed and grass killer guide explains when a nonselective product makes sense.
How to kill poison ivy vines on trees
- Cut the vine near the groundSaw through the vine about 6 inches above the soil, wearing full protection.
- Treat the stump right awayWithin minutes, brush or spray a concentrated triclopyr or glyphosate product on the fresh cut, following the cut-stump directions on the label. Waiting lets the cut seal and the treatment fails.
- Leave the upper vine in placeCut off from its roots, it dies on the tree. Pulling it down sends toxic bits everywhere, and the dead vine is still loaded with urushiol.
- Treat sproutsSpray or cut any shoots that come back from the base. Never spray poison ivy leaves up in a tree canopy.
The same cut-and-treat method works on woody seedlings and saplings; see our guide to weed trees.
Can you kill poison ivy naturally?
Yes, with persistence: pulling, digging and repeated cutting all work if you keep it up until the roots run out of energy. What does not work are the homemade sprays that circulate online. Vinegar scorches leaves but the roots regrow. Salt stays in the soil and keeps anything from growing there. Bleach and dish soap harm soil life and nearby plants without reliably killing poison ivy. Our homemade weed killer guide explains what these mixes can and cannot do.
How do you dispose of poison ivy and clean up?
- Bag it: put all plant material in heavy garbage bags, seal them, and put them out with the trash. Do not compost poison ivy.
- Tools: wearing fresh gloves, wash shovels, pruners and saws with warm water and detergent; rubbing alcohol also removes the oil.
- Clothes: wash them separately from the family laundry, in hot water on the longest cycle. Wash the gloves too, or throw away disposable ones.
- Pets: if your dog ran through the patch, bathe it while wearing gloves.
What if you touch poison ivy?
Wash the skin as soon as possible with soap or dish soap and plenty of water, or with rubbing alcohol; the sooner you wash, the more oil you remove. Scrub under your fingernails and wash anything that touched the plant. Go to an emergency room right away if you have trouble breathing or swallowing, swelling of the face (especially an eye swelling shut), or a rash around the eyes, mouth or genitals. See a doctor if the rash covers much of your body, comes with a fever, or looks infected.
How do you keep poison ivy from coming back?
Birds eat the berries and drop the seeds along fences, under trees and at the edge of woods, so new plants show up in the same places year after year. Walk those spots each spring and pull seedlings while they are small. In beds, a layer of mulch makes seedlings easy to spot and pull; in the lawn, thick turf mowed regularly keeps poison ivy from spreading in from the edges. Keep children and pets away from areas you are treating.
Common mistakes
- Pulling vines off a tree while they are still rooted, instead of cutting at the base.
- Using a string trimmer or mower on poison ivy without full protection.
- Touching your face or phone with contaminated gloves.
- Throwing dead vines on a burn pile.
- Stopping after one treatment: the roots survive and send up new shoots.
FAQ
What kills poison ivy permanently?
A systemic herbicide that reaches the roots: triclopyr or glyphosate sprayed on actively growing leaves, or applied to freshly cut stems as the label directs. Poison ivy is a tough perennial, so plan on a second treatment for any regrowth a few weeks later or the next season. Pulling small plants out with the roots also works if you get every piece.
What kills poison ivy but not grass?
Triclopyr. It is a selective herbicide that affects broadleaf plants like poison ivy and spares lawn grasses, which makes it the usual choice for poison ivy growing in a lawn. Check that the product is labeled for your grass type. Glyphosate kills grass too.
Is dead poison ivy still dangerous?
Yes. Urushiol, the oil that causes the rash, stays active in dead leaves, bare winter vines and roots, and on tools, gloves and clothing, for months and even years. Handle dead plants with the same gear as live ones.
Does vinegar kill poison ivy?
Vinegar burns the leaves it touches but does not kill the root system, so poison ivy regrows. Pennsylvania extension specialists also advise against homemade mixes based on salt, bleach or dish soap: they damage soil or nearby plants without reliably killing poison ivy.
Can you burn poison ivy?
Never. Burning carries urushiol in the smoke, and breathing it can cause a severe allergic reaction in the eyes, nose, throat and lungs. Bag the plants and put them in the trash instead.
How do I remove poison ivy from my yard without touching it?
Wear long sleeves, long pants, closed shoes, eye protection and heavy waterproof gloves. For a few plants, slip a plastic bag over your gloved hand, pull the plant, then turn the bag inside out over it and seal it. For larger patches or vines, spray or use the cut-stem method so you handle the plant as little as possible.
