OK I have the same problem as the OP and my mouse (I'm trying to believe there is only one) ate all the peanut butter, and walked right back out.
This is starting to really piss me off.

Wow, they've already figured out a way around that. I guess that saying, "How to build a better mouse trap," is not just a cliche.

My sister actually has some big, huge black box thingie. The OP can do an
Amazon search for it.
We were sitting in her kitchen at night when I heard this subtle whoomp! sound and a click. I asked what that was & she said it was that door on the mouse trap box. She went over to check the number counter on the box & it had indeed clicked forward the mouse count.
She's the one who said it indeed catches mice, with no need for food.
I asked her what they did with the mice.
She said, the first mouse they caught, she & DH went down to the curb by the street & went to release the mouse. (No woods nearby - all residential.) Well, as soon as the mouse let go on the street & he took one look around to get his bearings, he ran right back towards their house!
Needless to say, they didn't do that again.
Now, let me tell you about my experience with glue traps. I thought that they were a great idea. The mouse gets stuck to the glue trap, I lift him off, put him outside and all is well. NO WAY! My kids were younger, waiting to go outside for the school bus when we heard this screaming sound. I went into the living room, where I had put the glue trap and there was this poor mouse, his whole body stuck to the trap.
I went through the same thing with a
HUGE rat stuck on one of the rat glue traps the exterminator laid down.

(Notice
I did NOT recommend glue traps in my previous post.

)
It was 4 am & I hear this thrashing & screaming coming from the kitchen. I knew it was a rat. I turn on the light. I don't know which one of us was more frightened staring at each other.
I KNEW the rat wasn't dying, he was just stuck to the trap.

It would take
days for him to die of starvation on a trap. (A little oversight on the glue trap makers.

)
I also had a feeling the rat was way to big for the trap. Eventually he would wiggle his way off...then he'd be mad

...he was in the house with me...
If I had had long fireplace tongs, I would have clipped the edge of the trap with it & left it outside. I thought about taking a cast iron frying pan & hitting him. But the thought of rat splattered all over the place, made me nauseous.

And frankly, I just couldn't do it to a poor, defenseless rat. It would be different if he was foaming at the mouth & chasing me.
I went back to bed and listened to the rat struggling for another 45 minutes, until he finally got himself off the glue trap. He left a big patch of fur on the trap. It was like hair waxing for rats.
