Well I had a big cheese ball container that I was housing crickets in. The crickets eventualy all died and I forgot about the container. I found it a while ago and saw a couple moths in there. Well I still left the container to "develope" some more. well I completly forgot about it and just found it. there is tones of little gray moths!! I found It pretty interesting. Just thought I would share this with you all. I think they are surviving off the cardboard and dead crickets (but it dosn't smell because they were tiny crickets).
