Hello again I have a question about death heads + discoids. I read that dubias young will actually keep a colony clean by eating waste, will the discords + death head nymphs do the same?
I don't think the nymphs will do much in terms of eating the waste, you should consider getting some lesser mealworms, (Alphitobius diaperinus) for that.
Agreed with getting lesser mealworms. I know some people also recommend dermestids, but I can't stand them and since I have an insect collection I'd rather not have it eaten lol.
