My dubia adults are dying fast enough to worry me but slow enough that it's not a disease I think. I don't see any parasites, and I just cleaned the bin a few days ago. But it's mostly the females who are dying, I've had maybe 5 males out of 20 roaches die. I'm not sure if they've just gotten to the end of their days or what. They are dying about 2 or 3 every week now. I'm wondering if I have enough ventilation.
