I buy crickets 1000 at a time and keep them in a big rubbermaid bin in a dark closet. I usually cut a few potatoes in half and put some gutload in to feed them but I would say about half of the thousand die every time. Any tricks or sugestions on keeping tons of crickets alive?
Do you have eggrate or some other material in there for them to climb on? Are you providing water crystals? Is it staying warm in there? Are you removing the dead crickets? Those are the biggies that I can think of.
