I currently use Peat moss as substrate for my AGB millipede. I've noticed after about 2 weeks its starting to stink. Im just wondering how often the substrate should be changed or cleaned? if cleaned, what is the easiest way? and if there are special techniques to help avoid odor? I am also open to a change in substrate if anyone knows of any alternative that is more odor absorbant or that the millipedes enjoy more. Any information would be appreciated Thanks!!!
