I'll never buy another Poulan either. Do yourself a favor and buy a Stihl. Mine has yet to fail me.
I was TERRIBLY allergic when I was a kid until I decided to eat it so I wouldn't have to go to school. (I wasn't fond of school. The dentist was better). It DID NOT WORK. It was either that or I out grew the terrible allergy. Yeah, if I mow it wearing shorts and it splatters all over my legs I get it. I scratch a some, but it heals soon enough. No biggie. Nothing like it once was. I'd have done it for you had I been there. But I wouln't have dressed in a costume, as you did.
Be aware that it will sprout from the roots. It is a very hardy vine. Make sure that you have some RoundUp on hand when it sprouts back out. Watch for it in the Spring!
I just let mine grow. I leave it alone and it leaves me alone. It's a pretty vine.
