The slugs are out in force right about now. You don't always see them, being the nocturnal creatures that they are. But the next morning, you certainly do see the damage done to the garden.
If you are looking for a way to rid yourself of these pests without using toxic chemicals, consider installing beer traps in your garden. Slugs love beer! If you sink a container of beer into the ground so that slugs can crawl into it, they'll eagerly drown their sorrows, and themselves, in the brew. All you have to do is come by every day or so, scoop out the dead slugs and top up the beer supply.
You probably have all the "equipment" you need for making traps in your kitchen right now. A glass jar, a large empty tuna can, a plastic margarine tub - any of these will make a fine trap. Next you'll want something to use for a lid, as shown in the drawing below, that will serve as an umbrella. Then dig holes and install the containers, sinking all but the top 1/4" into the ground. (Leaving a bit of a lip exposed at the top will keep rain from running into the trap.) Now you're ready to add the beer - the cheaper the better - slugs aren't fussy.
If plying slugs with alcohol doesn't appeal to you, there are many other non-toxic ways to protect your plants from slugs. Our friends at Eartheasy have a long list of effective methods, which feature, among other things: garlic, copper strips, seaweed, coffee, or adjusting your watering habits.

Whatever method you choose, you'll be able to protect your garden without having to use toxic slug baits.
