So I recently moved my Giant African Mantis into a bigger enclosure since he outgrew his old one. But I noticed mold growing in the bottom, I cleaned all the mold i saw out and then when I woke up the next morning I saw the mold growing on his wooden sticks. I'm currently cleaning everything in a bleach and water solution and soaking his wood and after they dry I will bake them. But will the mold come back? How do i prevent this from happening? It's it common?
