What is Poison Ivy?
Ironically, poison ivy is neither a poison or an ivy. It's an allergen and a member of the cashew family. It, along with it's cousins, can cause a red, itchy rash called allergic contact dermatitis. The body considered it harmful and reacts, fighting to protect you from it . . . but you may not appreciate the attempt! You become sensitive to the oil through contact, sometimes over many exposures over many years, sometimes on first contact. Here's a link to a WebMD Topic Overview and one from the Mayo Clinic. For more detail you might want to check Wikipedia's article on Toxicodendron. Captain John Smith wrote about poison ivy in the early 1600's and originated the common name because of its superficial resemblance to English Ivy or Boston Ivy. And did you know that the cashew we all love roasted and salted is actually a seed found inside the cashew apple which contains the very same urushiol? |
Poison Ivy is common and pervasive in New England.
It grows pretty much anywhere and can be a free-standing shrub, a ropelike vine growing up a tree or a trailing shrub along the ground. It has three leaflets attached to the same smooth stem. They are sometimes a glossy, bright green but may be dull, and sometimes colors other than green. NOTE: the scouts used to teach "Three small, shiny leaves." Three is always true but glossy and small may or may not be true. I've seen 8-9" poison ivy leaves and, at least in my experience, more often flat, matt or satin (to compare to paint) and only occasionally gloss. |

When Can I 'Get' Poison Ivy? You can be exposed any time of the year but less likely in the winter when the leaves have dried up and fallen to the ground. You can still 'catch' it in the winter from the stems of plants whether on the ground or growing up a tree. Unfortunately, there are no "Leaves of Three" to see in the winter so you need to know where you are at all times, hopefully in reference to a summer visit. Mature vines growing up trees are still easily identified by their 'hair' (see photo above) but the poison ivy stems sticking up through the snow look just like any other twig. |
How Can I 'Get' Poison Ivy? |
1.
|
You get a reaction to poison ivy when you your skin comes in contact with urushiol, the oil in the leaves, vines, stems and roots of poison ivy and it's menacing cousins. Physical contact is needed. Just being near them does not spread the irritant. |
![]() The exposure for the hands picture above was from some beautiful green and white berries on vines collected for Christmas decorations. |

|
Playing with a dog that has brushed against a poison ivy plant - thankfully, man's best friend isn't usually affected by poison ivy, they just pass it on unknowingly to their loving master. | ||
3.
|
Clothing that has come in contact with urushiol (even someone else's clothing). If you suspect clothing has come in contact, wash it separately. | ||
4.
|
Mowing the lawn, especially around the edges. Mowing won't kill the poison ivy but it can really spread the oil around. If you know you have poison ivy in your lawn, let it grow so you can see it and kill it. Once it's dried out, mow again. | ||
5. |
Burning poison ivy - REALLY BAD - breathing the smoke can produce life threatening reactions in your lungs. |
"Help . . . I've been exposed." Exposure involves direct contact with urushiol. Quick action is needed before the oil begins to be absorbed by the skin (up to10 minutes). |
1.
|
Cleanse the skin with lots of rubbing alcohol if you have it. If not go to next step. |
Jim, Thanks for your help in taking care of the poison ivy. Great service!

|
2.
|
Wash the area with plenty of water (any temperature is OK, cool will keep the skin pores closed) - NO Soap until next step (as with any oil, soap will break up urushiol and make it easier to be absorbed). | ||
3. |
Shower with soap and water to remove any remaining urushiol. | ||
4. |
Clean tools etc. with rubbing alcohol, taking care to use disposable gloves. If you don't have rubbing alcohol, rinse thoroughly with soap and water. |
"Help . . . . . . my yard is infested - what can I do?" |
5.
|
Don't try to pull it up. Even if you are fully protected and you don't contact urushiol, some of the roots will almost certainly break off and the plants come back.. |
Thanks for getting the PI under control. Hopefully I can keep it that way!

If you have only a few plants, you can apply Roundup per instructions on the label. | ||
3. |
Watch especially for poison ivy in the trees. If you don't get those, they'll be seeding your yard.. | ||
2.
|
Avoid direct contact with any part of the plants. | ||

What about Poison Oak and Poison Sumac? In Massachusetts, it's pretty safe to say we have no Poison Oak (T. diversilobum) which grows mainly west of the Mississippi. I've never seen live poison oak. Next time I get to California, I'll try to look for some. It's also unlikely that you have any Poison Sumac in your yard since it grows primarily in very wet, swampy areas. I've only seen one poison sumac plant in Massachusetts (Hutchins Pond, Concord) | .
He went around my property and discussed the poison ivy situation in my yard. He's very knowledgable . . . He was prompt and did what he said he would do. His demeanor was pleasant. I'm glad I did it.

Sprayed all visible poison ivy on property on two separate occasions, several weeks apart. We had a pretty extensive problem, poison ivy in many different spots. This seemed to do the trick. . . they offered a strong guarantee of their work and promised to return if the poison ivy does. They were prompt and friendly.

Optional - Annual rescan of your yard to treat any new poison ivy. Remember, the poison ivy we kill is DEAD. It won't ever come back. But we can not treat seeds that may already be in the ground or that may be dropped by birds who love to eat the berries for food in the winter but can't digest the seeds. |
