Yeah Cheekon: The worms are most likely "nightcrawlers." These are the common worms used for fishing. They are easy to raise and fairly easy to pick wild. Water your lawn, then walk softly at night with a flashlight with a red filter (use a red plastig bag if needed) as most animals (including predators i.e. dogs, raccoons) do not see red light. Most sold for use in fishing are picked at golf courses. Golf courses are notorious for chemical use so I have no idea how long that stays in the system of the worm. Worms are the major recyclers of plant matter, loving apple leaves most of all. They also can be raised in an old fish tank (in a dark place) and fed on newspapers. Fishing magazines often have articles on how to grow your own in a homemade plywood box. Happy hunting...
