It is often underplayed how much poison ivy can be spread after the initial contact. It isn’t the poison ivy plant itself, but the urushiol that has the potential to be spread after the first contact. This is especially true if you do not realize you and Poison Ivy have made contact. I speak from personal experience and every few years I face this problem. For me, it is an occupational hazard, but I want to shed a little light on how easily this can occur for just about anyone who ventures off the sidewalk.
Urushiol is an oily substance that is present in all parts of a poison ivy plant. Unfortunately, every part of the poison ivy plant carries the oil that results in itching and painful blisters for many people. The substance is found in the leaves, stems, berries, and roots. It can even be present after the plant is dead. It can be transferred by the root even when dormant. I know this one from personal experience.
If you know, or expect, you made contact with poison ivy you can prevent a reaction. You do need to act quickly though. Immediately use rubbing alcohol to wipe down any skin that was exposed. This removes the oil. Remove all clothing, shoes, gloves, etc that may have made contact. Put them all in the washing machine with detergent and give them a thorough wash. Make sure to clean anything else that may have made contact with the plant. I have read you have up to 8 hours to prevent the results of contact. I have not put the 8 hour timeline to the test however. I have successfully utilized these steps several times with a timeline of 2 hours or less.
Once you have had the itching and blisters resulting from contact with poison ivy, you will not likely forget what it feels and looks like. If you notice symptoms indicating an expected exposure, it is important to make sure you remove the oil from anything you may have touched. The reaction can take several days to show up so you need to think back to all the possibilities of what you’ve contacted during this time. This may include the inside of your vehicle. Make sure to clean the seatbelt, steering wheel, door handles (inside and outside), and seats. Consider the items you may have had with you where you likely were exposed. In my case, that would include pruning shears, work shoes (including laces), and a work belt. Consider bedsheets, pillow cases, and blankets. Removing the oil from all items is important to avoid repeated contact with the oil that causes the reaction.
Be careful out there! You expect to find poison ivy taking a hike in tall grass or off the beaten path. Unfortunately, it is often where you don’t expect to find it that leaves you itching and uncomfortable. The few times I have had a reaction have all been after spending time on a residential landscape where I had not seen poison ivy present before. Poison ivy doesn’t always look the same. It can take multiple forms from a vine climbing up the corner of a house, a plant growing amongst your perennials, or an opportunistic vine weaving through an Arborvitae 5 ft off the ground. Just remember “leaves of three, let them be”.
