I apologize for the delay in responding. We were flooded with questions and are working to catch up! There aren't really effective chemical controls for slugs, and it's impossible to eliminate all of them, but you can greatly control their numbers with a variety of methods. Here's an effective way to get rid of slugs that won't harm you or the environment. Since you've tried the beer, another method is to use barriers of diatomaceous earth or sawdust. Diatomaceous earth is basically tiny, fossilized silica shells made into an insecticidal powder. The slugs will crawl through it, be cut, and eventually die.

You can also create places for them to hide during the day, such as boards, garden pots, etc. over holes/depressions in the ground. They'll crawl under and can be easily collected. Finally, you can go out at night with a flashlight and collect them around plants where you have seen signs of damage. It's an ongoing effort, not a one-time deal with slugs. Good luck!
