I've lived in shacky rural housing for 30 years so have had lots of experience with mice. In my experience: snap traps best, and buy new ones when the old ones get TOO hair trigger or not snappy enough. A good snap trap kills almost instantly about 90% of the time. Bait with peanut butter, they have to work to get it off, giving the trap the max. time to work. Dead mice thrown in the field disappear within a few hours...something takes them. If you have one mouse, expect at least one more...they travel in pairs, so reset your trap after catching the first one. Place trap longitudinally where they run. Behind the trash basket in the kitchen has always been a good spot for me, no matter where I've seen them.

To keep them out of dressers (having to launder tons of winter clothing in summer, sheets, towels, etc. is no fun) upend and cover bottom with screen. If they nest in a drawer you might not find them for a long time so prevention is worth the effort.

Don't use Decon...aside from the astonishing amount of stench that can come from a tiny dead creature under the house or in the walls,
it's a bloodthinner and destroys not only mice but anything that eats the dead mouse, like cats. Glue traps are an abomination.

Encourage owls...their casts are full of interesting mouse bones, tiny intact skulls, etc.

Electronic emitters are famous for not working. Cats equally famous for the opposite. Dogs less effective...I've seen mice run right over the backs of sleeping dogs and their response time ("Wha????) is usually just not fast enough.

In this part of the country Hanta virus can be a problem, so pet wild rodents in the house not a good idea, even for the soft-hearted.
