Virginia Creeper, which is stunning in fall, but has a quite different leaf shape and growth habit.
This is the best time of year to catch up before it takes over next spring and you are no longer easily able to distinguish from all the other new, green things. My control method is similar to a hazmat team. Before I even start, I open up my clothes washer and set a path from door to the washer and to my shower so that I do not have to touch any walls, doorknobs, light swotches, etc. to get to them after exposure. I put on leather gardening gloves then grab some newspaper sleeve bags. I pull those on my hands up to my elbows and then put rubberbands over to keep them in place. I often double-bag my arms to be sure of no break-through. I then get grocery bags and rip out the poison ivy and put it in one bag, then double that bag. Then carefully peel off my arm bags and place them and the poison ivy-filled bags in another bag for good measure. Never, ever compost it or burn it.
Note that I took all of these photos this morning in one 20-yard patch of Poison Ivy on the edge of a park and a state highway in Montgomery County, Maryland. The amount of color variation is amazing and runs from bright yellow-green to dark green through yellow to oranges and burgundy red. This is just feet from a playground and a metro bus stop, so BEWARE in your travels and haunts where you step! Have a wonderful Halloween!
