Hotspur, thanks, I'll try that. My mother's method is just a bit not my taste: large jar (Horlicks for preference) of brine. Insert snails by hand. Our garden had dozens of them. I don't like pellets, though I'm using them at the moment, and can't get soot. I've tried lobbing them into the middle of the lawn for the thrushes. They never took to the beer.
