i havent kept them in the fridge for fear that they would freeze because i had put some worms in there and they kinda froze poor things, but i dont want to mess with the temp because its not my fridge (i live with someone else) it shouldn't be too humid there just in a plastic "shoe box" with a plastic lid with lots of holes slashed into the top of it,for air, sitting next to the frog tank with only the wood shavings they came in ...ill be going easy on the wax worms though my frogs were ,well i dont want to say skinny because that would sound like they were unhealthy, but they were smaller one day and fat the next it happened that fast lol
