When you fish worms and have leftovers at the end of the day, dump the worms and grass they are packed in into a bucket of salt water for a few minutes. They will freshen up and it will clean away their metabolic wastes. Put them back into their container and refrigerate them. They will last several days, hopefully until your next fishing trip. In these conditions the fish will feed by smell rather than by sight.
Natural bait produces the scent to attract the fish.
If you insist on using artificials, then add a scent to them. Bunker oil is a good one to try. Chumming also will bring the fish to your offering. Anchor and chum with bunker or clam. Use fresh bait on the hook.
