i only mist when they are in shed mode daily (should have been specific). but i do miss daily with the brazilian rainbow boa because it needs the humidity.
and even when i mist their enclosures i wait until they get bone dry, i dont mist them like every hour. it would be every four -6hrs if even then because the water dish keeps it humid.
And there isnt anything in their enclosures what would cause mild dew to grow or mold because i use paper towels with the BCIs.
