I use these traps:

baited with just a bit of peanut butter. No poisons. I'd rather have a quick kill than the sticky traps do.
Check them daily. Mice procreate fast, so you if you aren't catching them all in a pretty short time, the problem will persist.
Yes, these are the ones I've used after the stray cat that adopted us got too old to hunt. They always work for me, and I just used peanut butter. Easy to bait, easy to set, easy to empty. That 90 degree action just makes it so much easier to handle - you don't need to get to the part that is on the mouse, just press on the 90 degree bar part. Several keys:
A) Get a BUNCH of them (at least four), you want to catch as many as you can as quick as you can. And having several set around the area increases your odds of catching at least one per night. Mice leave a scent trail (their urine/feces - gross!) that others follow, so you want to get rid of them fast so others are not following.
B) I rarely need to re-bait them, the mouse trips it before it gets to eat any of it, so just dump the mouse into the garbage bag, reset, and you are good for at least a week (though I did catch one in a trap I left set that had year old bait in it - peanut butter really doesn't go bad, as far as a mouse is concerned). When I was re-baiting the larger chipmunk traps, which were outside and ants would get the bait over a few days, I filled a baggie with some peanut butter, cut a corner, and squeezed out a bit like a pastry bag - easy and quick and no mess!
C) Recommended: I attached each trap to a 12" long thin plank of wood. This makes it easy to set the trap deeper in a hidden place. And though it doesn't seem to happen very often with this brand of trap, sometimes the trap will just catch the mouse by a little hair/skin on the side, and the mouse will drag the trap away. It might end up somewhere you can't reach, and create a stink, or you just lose your trap. With the board attached, it won't be able to drag it far, and you will be able to retrieve it easily.
D) They should be placed perpendicular to walls, bait side against the wall. Again, use several of them each night.
E) Make sure they are sensitive. Test with a stick. If it doesn't trip easily, a little veggie oil on the catch may help. This was easier on the old wire snap-traps, I could bend the catch until it was a hair trigger.
F) Leave them out year-round where you can, and check them. Best to get that lone scout right away, before it leaves a trail for others to follow, or makes a nest and you've got babies there.
I have not had the problem of them coming in from the side and not tripping them, as in the earlier video, but that's a different brand than these (and some of the other similar ones I tried did not work as well - these had the best reviews at the time on Amazon). I did have that problem with the larger 'rat trap' size that I used to get rid of chipmunks (striped ground squirrels, other names in places) that were digging up DW's flower beds. So I added sides to the plank I mounted them to.
Please don't use glue traps! I'm not really an animal lover, and I'm not all that squeamish, but that's a terrible way to die. These snap traps kill them in seconds, sometimes instantly (I've actually seen some chipmunks get caught, it was fast in these brand traps, others sometimes caught them by the side, not nice). I figure this death is better than what they would probably experience in the wild (I've see what they go through when the cat would get them - yuck!).
