I am building a rocket stove, basically a large cylinder with a smaller cylinder inside it. The smaller cylinder has the insulating material around it between it and the larger cylinder. What materials could I put between these two cylinders to insulate from the extreme heat?? Because I do not know where I can get vermiculite or perlite as suggested in the youtube videos. Thanks for your help.
Same thing happened to us, but we still had about a million baby crickets- so I wouldn't stress about it too much. Just keep an eye on your humidity, and make sure you submerge your vermiculite in a hot water bath to sterilize it (partly anyway). Of course let it cool down before introducing it into your breeding colony, but all in all, don't stress too much about it.
It may not attack the eggs now, but if the mold continues to grow, it may destroy all eggs. I would scoop as much of the mold out as you can and then let it dry out a little, maybe stop adding water to it.
