I had cleaned out my dubia tank, double-bagged the substrate (figured there would be a few nymphs mixed into it) and completely forgot to put it outside in the trash can.... for like three months.... It was really late at night that time and I was tired, so I had meant to toss it into the front spare room until morning so the cats wouldn't get into it. We weren't using that room for anything and had no reason to go in there and it completely slipped my mind that I had done it.
I was unfortunately reminded of it several months later when my husband went in there to move some boxes around and started screaming at me that my roaches got loose. :lol: I found about a dozen huge nymphs, so they must have been having fun in there since I know there wasn't anything larger than a 1/4 inch when I bagged them. They had chewed through the plastic and where molting fine - and this was the dead of winter without any heat in there so they were doing it in probably 55 degrees. I think they all lived once I "rescued" them and tossed them back into their proper tank.
