Organic slug control; the "Marie Antoinette method"

More than 1,500 slugs have been "organically controlled" in my garden in the last ten days using no chemicals or beer.  I use what I call the "Marie Antoinette method" using a powerful torch and dedicated pair of scissors after dark.
They are carnivorous.  Once a carcass is left on the lawn, there is almost a geometric progression of slugs returning in the following nights, which builds up to quite a heap.  You no longer have to go looking for them.  They assemble at the execution points waiting for you.
See http://www.bbc.co.uk/news/magazine-18672728 for slug news today.
The carcasses dry out -- eventually and almost disappear.  Foxes don't seem to eat the dead slugs.  And there are no longer hedgehogs to do so, as badgers have eaten them all.  I'll spare you any pictures.
