There are other 'poison' plants besides poison ivy. I even
tried removing it in winter temperatures around 10 degrees F.
Don't do it without extreme protection, is what I learned.
Even the stems have those oils.

The active ingredient in poison ivy, et al is an oil
chemically described very similar to oils in chicken fat. But
even detergents that are good on such grease still did not
stop oils from causing damage (itch). Those oils are also why
burning is bad. Dig a deep hole and bury the stuff when it
is clearly dead. And be prepared to go after stragglers that
pop up their evil little leaves later that (and the next)
year. Clearly poison ivy, et al come from the dark side - with
all its powers.

Yes, even those vines climbing into trees can be another
member of the Lord Vader family.
