Good tips!
I use beer traps, which is the most effective method here. I also use pieces of old logs or bark (boards work too, but are less decorative) where slugs like to hide and from where they can easily be collected and disposed of. I also make a habit of walking around the garden in the evening, when the dew has moistened everything and the slugs come out to feed and can be stomped on, speared, cut in half or whatever method of disposal one prefers.
The new type of Ferramol, which is slow to take effect compared to the old type (which was also less environmentally friendly of course) does not work here - either the slugs prefer my hostas or other garden tidbits or they - somewhat infuriatingly - eat the pellets as an hors d'oeuvre before proceeding to the nearest of my precious plants.
William, I like the idea of baiting the slugs near the compost heap (and maybe in other places where they are likely to 'hang out') as that would probably mean they would be killed by the pellets _before_ reaching my plants. Certainly worth a try!
Another thing I have learned is to avoid growing things they really like - but I would be very sad if I had to give up on my hostas!
