Winning The Slug War

We have made a slug barrier that works. It uses no harmful chemicals and
doesn't hurt the slugs and snails. We were able to use reclaimed
materials for a large part of the input.
The barrier is a moat made of normal household guttering and kept filled
up with water. At night we can watch in glee as snails make a bid for
the plants only to be stopped in their tracks.

So how is this going to stop those soils dwelling slugs eating all my spuds?
It's the worst slug/snail problem we have.
