Mold in Cricket Enclosure

[tomboy1988]

Okay I've posted before about breeding crickets. Well, here I am again. The babies are hatched, eating, and growing, but the mold will not stay out of their enclosure. I constantly have to move them from one bin to another and the same thing happens! I don't mist them, I started using potatoes instead of cricket chow (the potatoe pieces stay in for a day before I remove them) And there is STILL mold! Is there anything I can do that will prevent it?
