Hello,
Something is eating away at my leeks. Small larvae type grub or worms
2 - 5 mm in size are found well down between the base of the leaves.
They leave behind a trail of mushy green debris. I think that they are
probably onion maggots. Is this possible, and is there anyway of
getting rid of them? I really like my leek and potato soup so any help
or advice is very appreciated.

Thanks,
John
