Disclaimer: Our worms are classified and described as Eisenia fetida or Eisenia andrei based on our breeding lines, supplier records, historical stock separation, and observed performance characteristics consistent with each species.
Due to the extremely close genetic relationship between Eisenia fetida and Eisenia andrei, and the existence of overlapping traits, cryptic lineages, and documented hybridization in scientific research, species-level identification cannot be guaranteed with absolute certainty without laboratory genetic sequencing of individual specimens.
Routine DNA testing of commercial worm harvests is not practical, and no species classification provided by our operation should be interpreted as a genetic guarantee.
Accordingly, species designations are provided in good faith and represent our best professional judgment, but are not guaranteed for legal, scientific, or regulatory purposes. All worms sold are intended for composting, soil health, and vermiculture use and are collectively considered red wiggler composting worms (Eisenia spp.).
