I buy a couple dollars worth of crickets and keep them in a critter keeper from wal mart.. I put cricket quencher in there and some baby oatmeal and whey and a crumpled paper towel for them to hide under.. If I can stand the chirping, they stay in the bedroom by one of the lamps to keep warm.. Usually they end up in another room.. As far as meal worms, I just toss them in the fridge..
