Poison ivy questions, answered straight

Three leaflets on every stalk, with the middle one on a noticeably longer stem than the two beside it. The leaves are 2 to 6 inches long, smooth and slightly glossy, with no thorns on the vine. Older vines climbing a tree look like they're wrapped in rusty steel wool, which is the plant's aerial rootlets. It is not a true ivy, it does not have serrated edges like a raspberry cane, and Virginia creeper, the plant most often mistaken for it, has five leaflets rather than three. If you are unsure, send us a photo rather than touching it.

Yes, and it is the only way we work. Herbicides on poison ivy are slow, frequently need repeat applications, and leave a dead but still-toxic plant standing on your property, because urushiol, the oil that causes the rash, stays active in dead material. They also soak into the soil your family and pets use. We remove the plant physically instead: vine, crown, and root run. When we leave, there is nothing toxic left to touch and nothing to wait out.

Not from what we take out. Poison ivy regrows from its root system and from creeping stems that root wherever they touch soil, so cutting a vine at the base does nothing but hide the problem. We take the root run out. What we cannot control is reseeding: birds eat the berries and drop them, so if there is untreated poison ivy on adjacent land, new seedlings can appear. Those are easy to pull while they are small, and we show you what to watch for before we leave.

It depends on how much there is, where it is, and how hard it is to reach, so we do not quote over the phone without seeing it. A single fence-line run is a very different job from a half-acre of woodland edge or a mature vine 40 feet up an oak. The assessment and the written estimate are free, and the price you sign is the price you pay, including hauling the material away.

Never burn it. Burning poison ivy vaporises urushiol into the smoke, and inhaling it can cause a reaction in the lungs and airway that is a genuine medical emergency, not just a rash. Pulling it by hand is safer but still risky: the oil is on every part of the plant including the bare winter stems and roots, it transfers off gloves, tools, boots, and pet fur, and it stays active on those surfaces for months or longer. Most of the worst reactions we hear about came from someone clearing their own yard on a Saturday.

Yes. Urushiol is present in every part of the plant year-round, including the bare vines, the roots, and the leafless stems. Winter is actually when people are caught out most often, because a hairy grey vine on a tree trunk does not look like anything dangerous and firewood gathering, brush clearing, and fence work all put bare hands straight onto it. Dormant-season removal is often easier for us, because the structure of the plant is visible.

Yes, and it is one of the most common calls we get. A mature vine can reach the crown of a tree, thicken to the width of a wrist, and put out branches that look like part of the tree itself, which is how people end up gripping it. We take the vine off the trunk and out at the root rather than just severing it, because a cut vine left in place stays toxic while it dries and drops toxic material every time the wind moves it.

Far less than you would expect, and much less than a bamboo or knotweed dig. Poison ivy runs shallow, so most of the work is careful hand removal along fence lines, tree bases, and bed edges rather than heavy excavation. We do disturb the ground where the root run sits, and dense woodland-edge growth leaves the area looking cleared for a season until it regreens. We walk the boundary with you before we start so you know exactly what will look different.

As soon as we have finished and cleared the site. Because we do not spray anything, there is no re-entry interval to wait out, no dead toxic material left standing, and nothing in the soil. That is the practical difference between physical removal and a herbicide programme, where the plant stays on your property, still toxic, for weeks while it dies.

It leaves with us. Poison ivy must never go on a compost heap, into a chipper, or onto a burn pile, and municipal green-waste collection is not an appropriate destination for it either. We bag and haul the material off your property as part of the job, which is included in the price rather than added afterwards.

We remove everything on your side of the line and take the root run right up to the boundary, which stops the spread rather than trimming it back. If the source is a mature vine on the other side of the fence, that vine keeps producing berries and birds keep moving them, so it will keep trying. Many of our jobs end up being done for both properties at once, and it is usually cheaper for everyone that way. We are happy to talk to a neighbour directly if that helps.

Yes. We keep capacity for emergency calls, because poison ivy problems are rarely discovered at a convenient moment: a camp opening in three days, a property closing next week, a play area where a child has already reacted. Call rather than using the form if the timeline is short, and tell us the deadline you are working to.

Yes. All three carry the same toxin, urushiol, and all three are removed the same way, physically and without chemicals. Poison sumac in particular grows in wet ground, bogs, and swamp edges where it is often mistaken for a harmless shrub, and it is generally considered the most potent of the three.

Yes. Giant hogweed, wild parsnip, and stinging nettle are hazardous to people in their own ways, and Japanese knotweed, kudzu, phragmites, multiflora rose, English ivy, Oriental bittersweet, mile-a-minute, and running bamboo are all invasives we take out. If you have poison ivy, you usually have at least one of the others alongside it, and it is more efficient to deal with them in one visit.

Yes, and that work is a large part of what we do. Schools, camps, playgrounds, parks, golf courses, marinas, and nursing homes all carry a duty of care over ground that the public walks on, and poison ivy along a path edge or a fence line is a liability that shows up in incident reports. We handle scheduling around your calendar, including out-of-hours and closed-season work.

We cover New York City and Long Island, the lower Hudson Valley, northern and central New Jersey, coastal Fairfield County in Connecticut, and the New Hope area of Bucks County, Pennsylvania. There is a page for each county we serve with the towns listed. If you are just outside it, call anyway, because we travel for larger jobs.
