No offense but I'm not overnighting crickets. Most are in large quantities and most will die off. It's just not economical. His humidity is fine, he has fresh water and gets a mist. I tossed two moths in before I left for work and I'll check when I get home. His size is about 2 inches and I'll get a pic when I get home. I'll remove his substrate and put some paper towels down. As for stress, I generally leave him alone and don't handle him. I'll check the pet store again tomorrow morning. If they are still out I'll probably just go hunt for some myself. I know it's frowned upon for potential parasites, but it might be the only option.
