Advice wanted on whether to clean or just buy a new bin for $10. It's going to cost me $50 of my time. 2 colonies- both in about 40 liter tubs. Dubia colony about 300 adults, 500 medium, and 500 nymphs-small. Rough estimate- I'd say about 4-5 pounds total. Orange head colony is about 1/3rd that size, same container. I know the little ones need some frass. There is no substrate and I use 4 pack coffee cup holders from the convenience store for them to climb on. Each colony has about 6 of these egg crate type things (I like them better than egg crates because there are holes for better airflow.
