My speckled king was loose for four days in my heating ducts.i found her when gettin ready for work in my bath tub looking for water.just look in dark small places throughout the room where it was kept IE under furniture, cushions,in shoes,etc...block the underneath of the door if it is not a main room.and look in closets as well.Also you could try baiting.Get an escape proof container and put a mouse in it with an opening large enough for the snake to get in, and the mouse not to get out...The snake eats the mouse, and can not fit back out.... :crazy02:
