I can top that, emmadogs.  I just recently gave up a storage building adjacent to a wetland that was severely mouse-infested.  This past summer I was cleaning and I grabbed an old copy paper box that had a spare printer in it.  After I lifted the printer out, I heard rustling in the box.  There was a mouse living in the box with my printer!  A very fat mouse. She perched on the edge of the box and saw me, and then took off scrambling.  I put the empty box in my trash pile.  About a week later, I asked a friend to flatten a bunch of boxes so I could put them out for the trash.  (Boxes have to be flattened or recycling won't take them.)  To her horror, she found seven dead baby mice in the printer box.  The mouse I evicted had recently given birth.

Anyway, since that was a storage building, I favored old-fashioned spring traps.  However, for indoor spaces, I use a multi-pronged strategy, everything but spring traps.  

My favorite are glue traps.  The Catchmaster brand sold at Walmart are the best.  

I also like snap traps, including Tomcat brand.  I don't like the idea of reusing them after they have killed a mouse, but they are a snap to empty and reuse, or you can just throw them away.  

The D-Con circular mousetraps are nifty, but I'm not sure I ever caught a mouse in one, and they're more expensive.  

The D-Con poison boxes are useful, and their emptying will tell you if you still have mice.

I don't favor live trap mousetraps.  I tried one of those once and caught two mice at once, who killed each other inside the trap and made an awful racket.

I have tried ultrasonic pest repellers with mixed results.  They made no difference in that storage building.  At best they are a passive accompaniment to an active program of mouse killing.
