DE sprinkled around the pots will kill them as they try to crawl across it to get to your plants. Sluggo is a good suggestion too, which is what I use in my veggie garden. I can seem to get the beer thing to work, because I keep drinking it all......

Lol

I'll try the DE. Wasting beer on slugs doesn't seem right........

DE won't work if there's wind or rain in your area, as the barrier will quickly erode. You can cover your pots in copper foil or make a copper barrier of some sort around your plant area. Copper is lethal to many slug species, but should not cause a problem for your plants in this manner.

Rob,

Get some cheap beer - the $5 for a 12-pack stuff. The slugs will come to it as if it were an artisan ale.
