Ok, but before I waste beer on snails what is going to happen? Is it poisonous to snails? Or do they get drunk, fall in, and drown? Also do you think they like Amber Bock, that's all I have? Thanks.
It's an old gardener's trick. I've never had to try it. I think they are attracted to it, then fall in and can't get out. There may be something else to it, like instead of drying out like salt, the osmotic gradient is opposite, so they get waterlogged. Not sure. It shouldn't take much, give it a try and let us know.
I did the same when we lived on the river went on a nightly slug / snail hunt . Sluggo will kill the large ones but not the tiny bush snails . I finally used rock salt around the bench legs out side and the foundation of the green house ,, Gin
