Red Wiggler Worms
You gave me a great answer about Red Worms being best for composters, but I'm having trouble finding them. Where are the best places to acquire a supply of Red Worms for composting?

Thank you for using eXtension for your vermiculture composting question. Red wigglers (Eisenia fetida) are preferred over night crawlers or earthworms (Lumbricus terrestris) because they tolerate the conditions of living in a bin better. Earthworms live in a vertical burrow that can be quite deep, red worms do not really have burrows living horizontally between the layers of organic materials migrating to the new food added. Red worms also tolerate the warmer temperatures of a bin better. Larger earthworms either escape from or die in worm bins.
This is primarily why we recommend this worm species for use in vermiculture bins. Here are some websites for more information about worms and vermiculture.
Worm growers are listed in the Directory of Vermiculture Resources by State in the U.S. and by Country. Also, red wigglers are often available at your local bait shop. Many fishermen prefer them to the bigger night crawlers. At least you won't have shipping charges. Rhonda Sherman, North Carolina State University"
