Being sensitive to PI myself, I try to gear up as much as possible. The best way to totally eradicate the PI is to dig it up. My advice - put on a long-sleeved shirt, long pants, shoes and socks and put on some gloves. Dig up the whole clump, getting as many PI roots as you can without touching it with your hands. Next - do you have any plastic bags from the store or newspaper? Put these on over your gloves and up over your shirt-sleeved arms. Now you have a double layer of protection. With your hands still doubly-encased, Pick apart the clump, getting as much of the PI roots that you can. I generally put the PI into another trash bag and put it in the garbage. Do not burn or compost it. You can also peel the bags off your hands and throw in the trash. I would then put another set of clean bags over your gloves to divide the daylily. Remember that the daylily will have some of the PI plant oil on it as well as your shovel or spade. When you're done, hose off your shovel and the daylily divisions with water. Discard the second set of plastic bags. Don't handle the plant divisions with bare hands for a while, always wearing gloves or plastic bags. Remember to wash your shirt, gloves, etc and best to wash your skin as soon as possible just in case there was accidental contact. Might seem like overkill and you may end up not being sensitive to PI but it's worth the effort not to suffer from a possible rash.
