Beer Traps to Bait Slugs
The most common piece of advice you’ll get when dealing with slugs is to put out beer traps. Beer traps are easy and cheap to make, and the traps work well because slugs are attracted to the scent of the yeast in the beer. However, we don’t recommend them as a first line of defense. These traps do drown and kill slugs, but they frequently also kill beneficial insects, so we recommend only going this route if you are dealing with an overwhelming infestation.
