There's one surefire way. suspend all the furniture in the house from the ceiling by ropes and pulleys. Erect scaffolding if necessary, but the feet of the scaffolding must be sitting inside buckets of kerosene, gasoline, or naptha. The mouse will not enter the buckets. This will basically clear the whole floor, but the spaces on the scaffolding must be wide enough apart that you can run through them to any part of the cleared floor.

Now shut all the doors.

Now plug all small openings...except ONE...in the floor or at floor level and empty all closets and cupboards. Stuff taken out of closets and cupboards must be thrown outside through an open window.

Now shut window.

Place bait in middle of floor. Peanut butter and bacon bits work great.

Wait till after dark. Mice get active after about 10PM or midnight.

The mouse will soon emerge through the one opening you left and head for the bait. IMMEDIATELY plug the opening from which the mouse emerged!!!

You now have the little rascal where you want him...trapped on a bare floor with nothing to hide under. Heh! Heh!

Now destroy that mouse! Armed with your trusty sledgehammer, shotgun or flamethrower, you can pursue the vile rodent around through the house and hound him to his doom.

Be careful not to strike any of the scaffolding or buckets while swinging the hammer at the mouse, firing the shotgun or activating the flamethrower. I know one guy who did that, he broke a section of scaffolding in his living room, and was he crushed under a china cabinet full of Royal Doulton that he'd been collecting since 1932.

Not good.

And the mouse escaped too!
