Holy MOLY...
I've watched some of the Better Mousetrap builds on the YT, which is good fun. Around my house they're mostly in the attic, walls, or roof. Very hard to set traps. The GF gets 'em in the basement, and keeps searching for their remaining entrances.
first two years in my house, while fitting obvious sill joints and such with 2-4 inches of ISO foam "plates" hand cut (and removeable - spray foam is an invitation to death threats)... and using a FLIR, i noticed a large amount of traps and bait from prior owners. after finding and sealing many "leaks" - a few days of -15F temps are a godsend

short of a smoke test (super vape!) i nailed most of the obvious with metal wool/firebreak foam, and silicone... no mice in basement. maybe 1-2? they were try hards, and suffered a long long journey when they finally met their end.
outside. jeeebus. they ate my trailer. most of the plastic is gone, and the wiring is 100% frakked. depending on temps, might rebuilt this winter just to get outside, definitely spring. need to haul things
i'm blessed to have a two car garage, cuz the tractor lives in one, and the car in the other. can't imagine rodents having their way.
wow, great trap, trap to get the super tall variant of "the standard bucket", rodent can jump like super high, ..., so either six inches of water or anti-freeze (it preserves the dead - so you could use a bio safe version or ... such), the liquid keeps them from jumping and drowns them fast.
the perfect mouse trap... i've invented it
basically you catch the suckers (with buckets), and their only way "out" is a one way connected set of pipes. which is a chamber. which slowly closes. no scare. and behind them 2000000000000 psi builds. and whoosh, freedom! a 45 degree exit pipe suddenly opens and ... yee hah, they're shot into space. okay, not really, but ideally far far far away. into a cliff. or so on, lol. self cleaning, automatic, etc...
alas, too many neighborhood people, dogs, cats, and door to door salesmen fall into the traps too

oh wait. yeah, probably shouldn't say that . lol. j/k fbi. it's okay! they're just a few miles away!
