When I was unemployed I would take a weed pulling fork and crawl around the yard pulling them up one at a time. Right after a rain is a good time. Otherwise the root breaks off and no real benefit.
But if you pull out the root they don't come back.
You can try Weed be gone and Weed need but I suggest pulling them out. You can make wine out out of them I have been told.

I like to do my hunting BEFORE I pull the trigger!
There is only one kind of dead, but there are many different kinds of wounded.
