Yes, the worms will find the leaves on the surface. These types of worms are "leaf litter" worms. They stay in the upper levels of the soil and eat decomposing leaf litter and things like that. If you are using any sort of organic soil (peat moss, coco fiber, etc), they will also consume that.
If you have any left, feel free to feed them to the toads. If they are on the larger side, you can cut them up. They are really quite good for them and it;s fun to watch them shovel one down.

My Marvin loves worms.
