You think snails are annoying in your veggie patch? Land snails are infesting wheat crops, pulses, vineyards and pastures in southern Australia, clogging up machinery and threatening vital grain export markets like Japan.

So far, nothing seems to stop them. Researchers at Charles Sturt University have turned to a tiny native nematode which seems to be particularly efficient at knocking off snails, by giving the creatures blood poisoning.
