I use household ammonia , mixed with water in a spray bottle which I call my slug gun , I find the slugs,remove them from the plant, and squirt them , very effective, no soap , no oil, and it is not harmful at all to the soil, I used to put the ammonia in a bucket and throw the slugs in, disgusting to clean up but also effective, I avoid spraying on the plant as it may affect the foliage that is sprayed.I also set up hiding spots after a night I check them in the am and take control of any at that point.
