Cat, I am convinced that "natural" worms are hardier and will keep longer than "treated" worms. Maybe it's something to do with damage to the mucous coating.

I know dug worms will last over a week in the fridge; storm-drenched worms I collect off the porch at out horse barn (although very active when collected) turn to smelly slush in 2-3 days in the same fridge.
