I try to point out poison ivy to my kids any time we pass it, they’re getting pretty good at identifying it. Hopefully good enough that they can avoid it better than I did as a kid.
This is a great video about how to remove the urushiol oil if you do get in poison ivy. Basically, imagine you are trying to remove thick grease from your skin: use lots of soap and thoroughly scrub the area with a washcloth. This method has kept me poison ivy free for the last ten years!
