Need clean 2-liter plastic soda bottle, scissors, stapler. Cut top off just above cylindrical portion of soda bottle. Invert top and insert into cylinder (should look like a funnel) and staple together. Drop slug pellets into device and lay on its side in some shady, popular-with-slugs area. Nestle into mulch a bit so it won't blow around. Attracted by bait the slugs climb in. Not being intellectually gifted, they cannot figure out how to get out. When it is very yucky, discard in trash and make a new one. Ancillary advantages - safe around birds, pets, small children. And you avoid getting slug-slimed hands as can happen with beer traps.
