Unless your yard waste bin has a very fitted top that will say closed unless you apply sufficient pressure to open, it will not keep the snails in place. You would be amazed at what they can get in and out of!!

They are pests and invasive ones at that - very few are true native species. Consider them to be the garden/crop damaging pests that they are and kill them off. The more you can destroy, the less offspring they will produce. You would kill off aphids or scale insects, cutworms or other damaging pests....treat the snails and slugs the same way. If you use an ecologically sensitive bait like Sluggo, the "killing" is out of your hands :)

Ok. I can handle Sluggo, just not the squishing myself. To note, the snails have made it to the top of my yard waste bin and are hanging out (literally) clinging to the top inside. They certainly are determined!

Yeah, I can't deal with squishing either....except those inadvertantly stepped on :-) But I have no qualms about picking them up (by the shell) when I encounter them and heaving them as far into the greenbelt covering of ivy and blackberries as I can manage! Truth be told, I have also tossed them into the road to face death by car......or hungry birds :-)

There are reports of them having a 'homing' instinct......but AFAICT, this has never been fully substantiated and the distance to which this might be attributed is not great.....maybe 50 yards or so.

My fallback is Sluggo :-)
