Getting rid of bush snails?

[Mr.Fakename]

In France we use various techniques to attract snails.

• Beer in a container. The yeast inside works wonders and they'll rush to drink
• A slice of fresh potato will also bait them
• Humid cardboard. They seek humidity at night and hide under

I guess if you remove enough of them daily, you can effectively keep their population under control in the long term. Not sure how to cook bush snails though.
