I use bread, or nothing. I've caught a lot of mice in unbaited traps. Mice are super curious creatures, and if the trap is in their path they often poke at it out of curiosity.
Bread works great; I moisten it and smoosh it into the trap platform where it hardens and must be chewed to consume it. I avoid oily and stick stuff because I reuse my traps. No sense throwing out perfectly good traps IMO.
I hate killing mice BTW. I have a couple of giant mice in my back yard who have completely annihilated the infestation of earwigs that plagued us for years. I see those mice out there nearly every day, and I tell them thank you, and I beg them not to enter my house. So far they seem to be listening.
I have no issues with mice as long as they are not in my house. But I don't mind killing them, I dump the corpse outside and it's always gone in less than a day, so some other critter is getting a meal.
I set mine with grapes, cut in half, with the grape skin in the trigger. The grape skin seems to be strong enough to prevent removal without triggering.
