I have a dubia colony. my banded crickets from LLL keeps dying. I buy 100 and put them in a Rubbermaid tub with 5 egg crates with water crystals, bug burger and carrots. temp drops to 60s at night and goes up to 70-80 during the day. each day I probably pick out 5 crickets. I don't leave dead crickets in bin. some times they will die at night and some times during the day. its frustrating. i'm only feeding crickets for diversity. Is it my source? I've only cleaned my bin with vinegar/water.
