Does she have a favorite hiding spot inside her cage? If so, leave some food under a heat source and move that hiding spot to be nearby. 9 times out of ten, if she comes out to get warm and have a snack, she'll want to hide herself under the familiar 'safe spot' to warm back up. She won't want to go far. Or you could place the food inside something, like a liter soda bottle, milk jug, a cardboard box with a small hole cut in it, or small carry-cage, anything that you think would make her feel secure after feeding.


Your snakes main priorities are going to be warmth and security. Look any and everywhere that provides a warm or snug hiding spot.


Snakes usually don't like to travel very far. Normally, I'd bet on them spending AT LEAST a day or two in the room they escaped in. Most snakes aren't big travellers. If she has escaped pretty recently, put a small strip of flour or corn starch or something across the bottom of your doorway. Not enough that she can't get through without having to inhale a face full of flour, but enough that if she does leave the room that way, you'll at least have a pointer in the right direction.


Leave her cage open in case she decides to cruise on home on her own. There's always a chance.


A lot of keeper I know suggest laying out glue traps, and then using oils to release the snakes. I would advise against it, however. Your snake could hurt herself struggling to get free, or could suffocate in the glue... it could just be bad. So, don't be surprised if your search for solutions turn up this suggestion, but please be very wary of using it.


Last but not least, don't beat yourself up. Most snakes are incredible escape artists. It can happen to the best keepers. Just keep looking, and also try to figure out how she escaped and what you can do to prevent future escapes.
