This is an interesting thread!!!
First to answer, I use peanut butter in this mousetrap:

The wooden ones doesn't seem to work as well, and this is wicked easy to set.
Now the interesting part.
From my youth, we've always used smoked bacon or sausage. Without fail, if there was a mouse, they found it.
Nowadays though, I can put a whole friggin' slab of bacon out on the table and not one miserable of them critters will even look at it!
Now another interesting thing about peanut butter.
I only get mice in the shop during mid fall and early spring, so I cast out like 10-12 of those traps in various places.
After getting 30 or so in total, it appears that I get them all and the traps stay baited... well with the exception of 1 or 2 of them.
For some reason those 2 seem to loose the entire load of the peanut butter overnight, and yet, the latch stays open!
At first I figured that there is at least one wicked smart or very very lucky mouse left in the shop.
Well, that is NOT the case!
One time I re-baited the trap early in the evening while I've stayed in the shop.
After a couple of hours I casually looked at the trap, only to find the sum'bitch empty!
So, now really curious, I re baited the trap again and kept on looking back at it frequently.
Lo and behold, after about 20 minutes a long ass trail of ants showed up! Line leading out of a crack in the floor, to the trap, to the peanut butter and then back into the crack!
Them little bastards in less than 10 minutes polished up a spoonful of peanuts, all without leaving a single trace!
