lost king?

[Iridium]

my nerves have been shot over this for the past three weeks; i'm worried sick and feel like a terrible keeper for letting this slip!

about three weeks ago a newly acquired speckled king, about ten or so inches long, happened to find a crack in the lip of the kritter keeper (that i never would've noticed in a million years ;___;...) and decided to make his best houdini impression. i've tried all suggested methods: the lines of flour in the doorways never yielded a single track, i had boxes and bottles with pinkies all over the place until they had to be disposed of, i sat up until about one in the morning for two days straight waiting for the bags i stuffed under all doorways not treated with flour to make sound. the day that he was lost and about two after i kept the cat secure in a downstairs room.
i don't believe he went downstairs and everything on the upper floor has been completely eviscerated looking for the little guy, but i never found a single sign of him (and because parts of the upstairs are being remodeled there's a staggering amount of places he could be!). i also checked in the heat vents the best i could then blocked them.

it's been awful cold lately so i was wondering if he crawled into a wall or the ceiling and went into brumation (although we do have a whole ton of places he could get warm to stay instead so idk why he would, but...)? i've ruled out the cat killing him because a body would've been found. i've left out little water dishes in every room in case he needs ever does come out to take a drink, but otherwise i'm at a loss for what to do. i've heard stories of people's snakes coming out months or years later...which is terrifying, in my opinion.

i apologize for the rambling and whining! i just would really appreciate a word of reassurance or tips from anyone who might know what else to do? also, for the sake of desperate curiosity, would it be acceptable to try and snag him with something like one of the sticky snake traps?

Don't use the sticky traps, bad idea. I had a albino Florida king that my wife let escape on the second floor of my house which has no openings that I could find. I found the girl 3 days later in my basement. Patience and keep using the pinkie traps, it'll turn up eventually.

Don't give up hope, all is not lost. Years ago I had a Ball Python that escaped. He was gone for more than 3 months before miracuosly re-appearing. Best wishes for a quick and safe return.

One of my BRB's went AWOL for three weeks. I found him because I put down a water dish/hide combo on the floor of the snake room, and found him drinking from it one day.

Check in furniture and stuff. I lost a 3ft Sonoran gopher snake when I was a kid. Looked forever. Gone for like a day. Then one day my brother flipped the recliner up and it was sitting right there on the foot rest, scared the crap out of my brother he jumped so hard he tipped the chair so far it fell. BUT he could have just as easily been in between on of the gears when he flipped it so I'm glad he was OK. Just be patient. Chances are he's within 10 feet of where you lost him though. The chair was near the tank I kept my gopher in. Check the ridges under tables and stuff like that.
