African Nightcrawler Composting Worms


African Nightcrawlers (Eudrilus eugenia) are exceptional composting worms, converting copious amounts of feedstock bedding into high quality castings in just a few weeks.

For vermicomposting, we recommend a density of 100 African Nightcrawlers per gallon of feedstock bedding material. These earthworms are larger than most other composting breeds, so expect approximately 300 worms per pound.

Orders received by Sunday 12 pmCT will ship the following Monday or Tuesday. Please read our Shipping Policy before placing an order.

Shipping is included in the purchase price.

Additional Information

Breeding Stock
All our worms are bred, hatched and raised here at the farm on the same high quality bedding we use to produce castings.

African Nightcrawlers do like it warm. They live comfortably and breed at temperatures between 70 – 80 degrees F, but temperatures less than 60 degrees F or greater than 90 degrees F for extended periods of time can be fatal.
