use papertowels as a substrate, check the water bowl too, they'll look like poppy seeds. Also, treat the inside, and around the enclosure with PAM. Or reptile relief. Remeber to always read the instructions. You cant spray the snake with the PAM.
Also, when did you get her? Its best to let her acclimate in her tub for 2 weeks before disturbing her. Only go in there to change the substrate, new water. NO handling. Then after 2 weeks, offer her a rat
