I heard (on GQT) that slugs and snails can track back over a certain distance, can't remember how far now, so lob them far. Though I can't imagine having much sense of where I'd come from if I was thrown a couple hundred times my body length.
They did an experiment on some TV show where they painted the shells of snails from different corners of the garden and overnight put them some distance away (I can't remember what) but the next day they were all back to their relevant corners.
