I have a deep moist sand/soil mix in the bottom of my cricket bin, to ensure that the cricket eggs remain viable. I hadn't heard anything about it being hot and dry, that doesn't match what I've read on their breeding requirements. The surface of the soil is dry, but it's damp beneath that. It should be an ideal environment for the cricks.
It's been down to 40 degrees F in the past few days, and the cricks are thriving. The cold snap apparently didn't bother them one bit, I've had no deaths. They appear to be gearing up for their final molt into adulthood.
I live in a VERY dry environment, and keeping enough moisture in the bin is more of an issue than having too much. I thought of the worms as a possible way to control mold due to cricket wastes. If the worms eat the cricket wastes, producing castes, then what I have is a bin full of perfect compost/fertilizer and healthy crickets.
I'm not sure why herps would be unable to eat red wigglers. Earthworms do not breed as quickly, and need deeper soil and cooler conditions, so I thought wigglers might survive in there better. But my primary concern is whether they will eat the cricket eggs.
