Agree with @Obelixx here. I've been doing that for a few years, since the bindweed crosses the fence from my neighbour's "garden" which they leave "natural". It's a long battle for a never-ending war.
Ideally yes but if you can't get to it just removing the leaves - food factory which feeds the bulbs - will eventually kill it.
I have its cousin, arum italicum, happily smothering a clematis I found struggling when we moved here. I dug out as much as I could but can't get it all without destroying the clematis which turns out to have gorgeous blue/purple flowers and is responding well to lots of TLC and feeding.
I now let the arum italicum foliage grow in spring as it protects tender new clematis shoots from any frosts but have just pulled up every single leaf and stem and flower of the arum. There was less this year and there'll be less next year until it's gone.
