I went to the store and looked through the "rodent trap" section. The only rodent sticky papers they had came with anesthetic in the glue, I'm very worried that it could kill her or something. I also bought some plastic box traps, though they're mouse-sized and probably won't hold her. I bought several window fly sticky traps too, basically clear plastic with heavy glue on it, but no other chemicals. I'm going to put the plastic boxes out with f/t fuzzies in them, spread the fly traps all around, and hope for the best. I've already lined some of the major walls with plastic bags, hoping to cause her to make noise as she moves along. If she's already found a way inside the walls, I probably won't get much reaction. I set her aquarium on its side in the room, put her substrate fairly thickly on what is now the "bottom" and put a UTH on the bottom, which is now the side. There is a water dish, a hide, and a f/t fuzzy on top of the substrate, and I've put a line of cornstarch along the entrance, so I will know if she goes near it.
I'm really hoping I can find her, but we haven't seen any sign, no poo, no shed skin, not even any of the dust along the walls has been disturbed. I don't know if this means she's still in the room she escaped in or if it means she already got outside. :/
I'll keep you guys posted though, I really love my little snake.
