This is "swinging the blue lamp" somewhat (police anecdote time) but when I was providing armed protection at Sir Humphrey Atkin's house in the early 90s; he and his wife would walk around their garden collecting slugs and snails. They then crossed the road outside and deposited them on a small green opposite. If the slugs/snails managed to cross the road during the night then same again the next night. Thankfully the IRA didn't know this went on.
