@Beman @teen apparently roach allergies are fairly common (a few friends had allergy testing and all of them had moderate to severe cockroach reactions).
I got hooked up with a colony of Dubia. The adults still skeeve me out, especially when near the bin and I can hear them scurry around *shudder*. That being said, I'm definitely getting desensitized and the nymphs don't really bother me. I do not handle them, though. My veileds love the small nymphs. All they had ever had were crickets so I think they appreciate the variety!
For those who clean the bins out infrequently, what do you do about the food remnants? I've found mine carry anything they can under the cardboard to eat. I occasionally find funky carrot chunks or orange peels pulled into the egg crate. Maybe I need to add more CUC (derm beetles?). I have darkling beetles, maybe I'll add some of those... although I haven't seen them actively eat at all yet.
