I have not had this problem yet luckily but if I were in the situation I would pick up anything off of the floor. Fold blankets and maybe put them in another room so it doesn't hide in the creases of blankets. Remember that they like to hide and slither really close to thigs so around and behind dressers, under or inside things that it could fit in. Keep the door closed so you know it is still inside and after a while of looking it should turn up. You might put its favorite hide on the floor. I'm not too sure how well that will work though. Good luck!
