May Day Wild Garlic

One of the downside of feeding birds in the garden is that they thank you by bringing in seeds and scatter them around. Thank you birds for this wild garlic - impossible to get rid of and spreads like wildfire. Also they dropped the seeds among Lily of the Valley so the new growth of leaves is very similar. I am waging war on the wild garlic but as I do it just seems to spread!
AAAAAARGH.
