Peanut butter is usually okay, but Nutella works better. Additionally, a little bit of dollar-store powdered chicken soup mix with enough water added to make a gooey paste will also attract mice.
McDonald's french fries also seem to be irresistible to them.
The bait should be changed weekly so the scent is strong.
Mice often travel up through floors by holes that radiator pipes come up through, or even plumbing. You can easily seal these holes by jamming steel wool (real steel wool, not SOS pads or Brillo pads) into the gaps and sealing it with cheap caulking.
I find that the sticky pads that fold into tubes work best, because once the mouse gets stuck in the tube they're a lot less likely to drag the tube around and get it stuck to furniture, etc.
And as to the PETA brigade on this thread, you can get very sick if you eat food contaminated by mice, and mice also carry fleas which can give you fatal diseases. They're not pets, or our friends.
