I've been collecting some for a misdemeanour I have in mind. So, on Sunday night when it got dark I take a wine bottle out to the back garden (which has a bit of wine left in the bottom) and catch some slugs. I push them through the narrow neck and they land in the wine. Next morning all the slugs I caught are all on their backs ****** as farts. Since then no slugs have been seen in my garden. Why? I'm Perplexed!
