White mold growing on moss?

This keeps happening since the box of moss I’ve bought, I thought I wasn’t cleaning it thoroughly enough but after replacing it again after washing it 5 times it’s become fuzzy again basically overnight? All the other mosses I’ve used have never had this happen and my enclosures conditions have never changed, could it just be a bad box of moss or is this normal? And most importantly is it crazy harmful for my lil snake? He won’t touch it anyway but I’ve removed it as soon as I’ve seen it everytime. Thank you ahead of time!!
