Podcast with a person who has studied it and controls of it. Talks about NY primarily but also N. WI.

His take, let it go, it will gradually disappear leaving just a few stragglers.

What to control instead. Many here won't like it but Deer are bigger problem.

Earthworms, Garlic mustard and deer and their relationships.

Interesting listen.
