Sphagnum Moss -- Mold Spores?

[Jim Smith]

I am not a fan of having any mold in my enclosures. Even if they are not harmfull to your snake, the spores certainly will drift outside the enclosure into your living environment waiting for the right conditions to grow. I would remove that dish of moss, clean the dish with bleach and replace the moss. That's just my two-cents worth.
