I kept mine in a bait fridge. I would get the styrofoam containers from the pet stores and keep the night crawlers in them. They would fit perfectly in the fridge. I would keep 3 or 4 boxes in the fridge, along with a styrofoam minnow bucket of minnows. I used the worm bedding from WalMart and they kept just fine. I would take 10 dozen out at a time and put in a small bait to go container and when I came back and had worms left over I never put them back with the others and would just put the bait container in the fridge. Next time I would add to the bait container what I thought I would need to use that day. EB
