We have a garden, but we hardly have any snails.
When I see them in a friends garden, I take them off her plants for her, & squash them underfoot.
My friend can’t make her self do that. Next time I find them at home, I’ll put them in a jar & take them down to river & throw them in, for the fish to eat.
We found some really large ones, at the 2 places we stayed at in Bali a couple of weeks ago. I moved them off the footpath & put them into the garden. When my husband mentioned the snails to the owner of 1 of the places we were staying at, he said they eat them!
PS: If you don't like squashing them underfoot, put some sea/table salt into a tin your going to be recycling, & put the snails into the tin. Hey Presto, they'll be dead in seconds! Then tip into a plastic bag from a bread loaf & place in the garbage bin!
