StillLearning - it sounds like you had leopard slugs which I have been told actually assist in the composting process. I often find them in my compost bins and just leave them but they are the only slugs that get preferential treatment.
I find coffee grinds round plants works really well, but also collect in bucket of salted water, but towards end of last summer slugs were actually climbing out of quite strongly salted water! Scary stuff- just how much salt is needed?
I believe it is the caffeine in coffee that deters slugs though it may also be the smell as they home in in tasty leaves by scent receptors.
You do need quite a lot of salt - it should dissolve them quickly, not allow them to climb out.
