Slugs - Pour a cold (canned) beer into a glass, and cut the beer can in half. Put the can into the ground so that it forms a little well, into which you pour a little bit of the beer. Slugs love beer, and they will crawl into the can and drown. Happily. Repeat this until you have pleny of slug beer traps, but don't drive afterward.
Also, if you have access to some copper sheet metal, surround the area from which you wish to exclude slugs with a copper edging. Slugs will not cross it. Once you initially rid the area of slugs, they will not return. (Install the copper just like the common plastic edging you might use to separate grassy areas from gardens.)
Also, if you happen to have pet turtles, they love slugs. If you are manually plucking slugs off your plants, give them to the turtles. I have one turtle who is too shy to eat in front of us. He eats well if we walk away and give him some privacy, but slugs are the *one thing* he will eat in our presence. Turtles are not hoggish, but both our turtles will eat slugs until they are so full they can no longer pull their heads or legs into their shells, and they have to sleep with their heads and legs just dangling limply.
