Mice found my daughter's Irish Spring soap bars tasty (they were for bathing, not to repel mice). I do the bucket traps occasionally (when I actually see a mouse, signs of a mouse or the dog thinks she hears a mouse). I use a solid mouse bait (D-Con or TomKat) that I cut into 4 "slices" as a backup (I only put it in a few entry points). If you didn't catch any mice with a 5 gallon bucket, then you may not have mice but rats, which requires a taller bucket ( a tall kitchen trash can at minimum or 45 gallon trash can).
If I had an "outside kitchen" (which I think is a pest attractor), I would keep a "slice" of solid mouse bait in that area at all times.
