Thanks for the feedback. There are many legitimate concerns re wild insects, but ways around potential problems as well. But never risk free.

A friend in Louisiana keeps nightcrawlers in a commercial cooler for 2 days, to allow them to feed. He buries 3-4 freezer packs in earth and dead leaves to keep temps down; or you can just store in frig and coat with supplements. Tests run by our nutritionists years ago showed that several batches of worms came in with a near ideal Ca: Phosphorus ratio, and that they were fine to use right away. Nutrients will vary with diet, of course, but I find them to be a valuable food item, esp for large amphibs, and so always find a way to keep on hand.
