Thanks so much. I put them in grande starbucks cups that I tape up the slits and pock pen holes in. I might not be keeping them warm enough. I think around 70 in my laundry room. When I set up a new culture they all die off about 3 weeks in and then in a week or two later they start to reapear. I then harvest them for a month or so. Then the beans looked like they all have holes in them and a little dry. There is a light tan dust kind of stuff that starts to apear. Then I throw it out. I make 4 new cultures a week. I would like to use less containers and produce more beettles. I have 28 adult Poison Dart Frogs and Mantellas to feed.
