We use Tom Cat bait blocks, they work like a charm. They also come with a bait holder so that kids or other larger animals can get to it. They do smell quite nice.
Check the video. I know it's a bit long, but there's a narrative with it, and the mouse really is unique in its ability to avoid being caught. I tried bait blocks, once in a small bait station, and once in a bait station I made by myself with a piece of four-way PVC connector. I tried the bait chunks by themselves, and in a combination I call "mouse bane." He simply wouldn't take them.
