Ok, just had an idea... probably a bad one, but it's worth throwing out there. Crickets smell. That's a fact; it's also a fact that they're loud. Well, I can't think of much to do about the noise level, but I have an idea about a possible suppression, or even end, to cricket smells. How about putting crix on a coco substrate, and seeding the substrate with springs? The springs would take care of the cricket poop and dead crickets, wouldn't they? Just an idea...
