One potential problem with glue traps is that mice can learn to recognize and avoid them. I believe they can even teach this to their young. It’s always a good idea to have a backup method.

A double row of traps is helpful too. Sometimes mice will skirt around a single row of traps, or set off one of the traps on the interior row without getting caught, and it’s the second row trap that gets them. Mousetraps are cheap, and sometimes it’s necessary to get extra depth.

Bacon makes a good bait because mice have to yank it off the catch and that increases the chance they’ll trip the trap.

That’s a good strategy for new places, although mouseproofing an old place is practically impossible. They can squeeze through tiny gaps. Sealing up does help narrow down the points where you need to put traps in old houses, though, so it’s not a waste of time.

There’s a downside and an upside to cats. The downside is if you have a big infestation, the cat may well only catch one or maybe two a night, and that’s not enough for population control. They’ll happily stay up all night tormenting a single mouse while the rest run rampant.
