I'm sorry your snake is lost.

I once found a loose snake curled up in the laundry room in some dirty clothes.

If you have wood floors or tile in some areas, they suggest sprinkling flour across doorways and then check every so often for a trail. That way you can see if you snake is coming or going or moving from room to room.

Another good trap to make is to take a 20 oz. or 2 liter pop bottle. Cut the top off and then insert it backwards into itself. Tape it down good and tight. Put a pinkie mouse in the bottle. The theory is the snake will go in to get the mouse, but will be too plump to get back out.

Good luck!
