Well that is the problem. It is difficult. I have been cutting them
down in patches( using sheers) and then using glyphosate. But the
nettles have almost lethal stings on them! well painful anyway if I get

You'd be better off either going over them with a lawn mower or
walloping them down with a broom and damaging the stems, then when they
are trodden down and bruised apply the weed killer to them.
