If they're just toad tadpoles, you can also try to boil lettuce for 15-20 minutes, they'll go nuts on that. Otherwise, if they're salamander larva, there are some really good articles on feeding them on this site.
For adult toads, small worms at first or pinhead crickets work pretty well, basically any small insect (non-poisionous) will work pretty well. They get easier to feed as they grow larger, because you can feed them larger food items.
