Well my girlfriend was checking on our snakes and noticed mold growing under their water dishes as well as near them. I'm sure that some spills occur when we replace their water because some of the tubs are pretty snug and a little difficult to pull out and put back into the rack, and a few of the tubs don't keep great humidity so we do have to spray them about once a day. I'm sure this probably contributed to the issue. We're using aspen bedding to, which after this incident I've learned is known to grow mold easily? Would any of you have recommendations on what action to take? Maybe switching to a different bedding? Newspapers? Or something different? Has anyone came across this problem before? Thanks for any help, greatly appreciated.
