Control of Arum italicum

They are coming up everywhere. The bulbs are very deep. I'll destroy a lot of good plants if I try to dig them out. Is there an herbicide that works? I've tried Roundup. It doesn't work. Maybe the waxy leaves don't absorb it, as is the case with ivy.

Those of you who can't grow it should be grateful.
