What Are Red Wiggler Worms?
Of the 4,000 species of earthworms, one stands out as best for home composting. The natural habitat of the little red wiggler, Eisenia fetida, includes rotting organic matter lying near the soil surface. Thus, it adapts well to the shallow boxes used for worm bins and to a varied diet of kitchen scraps.
