If you want them to metamorphose into flies, I wouldn't refrigerate them; I'd refer you to the articles above.Thanks ill give it more time. Should I store them in the fridge an keep feeding them bananas.
"Refrigerate" is technically correct, but probably overkill—literally. Keeping them cool can retard metamorphosis, but once you get down to 55F/12C they'll start to die off. A few folks here use a wine cooler (the kind you chill wine in—not the kind you drink ); I understand they operate at around 55F.
