All I mentioned is ONLY in the cricket bin, not in the chams habitat. Also, the water crystals are only put into the cricket bin after being fully hydrated. But I like the fact that you pointed that out for members that may not know
All that said, I never thought about a dried out water crystal in the cricket bin where a bug may carry one and in turn, get eaten by a cham where it can expand to a dangerous size internally.
My crickets typically don't out last the hydrated crystals. I can go through a couple of batches of crickets and then it's time to clean the cricket box out anyway and the crystals are still pretty well hydrated.....but it's something I had not considered so thank you for that <thumbs up>.
