Mouse Update Day

We discovered evidence of a mouse in the house last November and it remains uncaptured to this day.

Over the past three months, part of my daily mental load has been mouse management. I clean up mouse poop in certain parts of the house in an effort to induce migration towards areas more amenable to traps. I've filled in tiny gaps under the stairs that might somehow lead outside. I've tried traditional traps, humane traps, sticky traps, gravity-based DIY traps that would be more at home in a game of Mousetrap, and most recently, electric traps. I've use cat food, peanut butter, cookies, and granola as bait. I always make sure to handle the traps with a plastic bag on my hand to avoid any human scents.

Throughout the mouse war, this little asshole rolls up to each trap, checks it out, then bails:

Since I've only seen the one mouse on camera at any given time, I'm presuming that Little Asshole is a loner. I'm not conceding the war, but I have switched from Googling "mouse traps" to Googling "mouse lifespan".
