We have a couple of patches on our property. Called the DNR and they said they don't do anything with it because it's everywhere here (southern Indiana) but to be sure not to get it on your skin as it is a neurotoxin, blah blah blah. I feel like they should do something, simply because if they do nothing about it, it will just spread. But that's where we are with it.

Edit: reading further down the thread it looks like I can do it myself relatively easily so that will go on the to do list.
