Should I be worried if my sub adult Emps have not molted yet? I've had them for 4 months now. And, much to my dismay, I went to do a routine cleaning of substrate etc. and noticed a foul smelling sulphuric/rotten egg odor. Is it the substrate or too much moisture in it that might be causing them not to molt? Temps are at 90 via IR 75 Watt and humidity at about 80%. I'm stymied as to what the smell is and why they haven't molted yet. Oh, the substrate is coco fiber (eco earth) and I don't know who is eating how much but I throw in 5 crickets every week and a half and they seem to hang around for a few days and then start to disappear. Thanks so much for your help.
