Vermicast

Vermicast

Vermicast (worm manure) is stabilized organic matter which has been produced by the interaction between composting worms and soil microbes during the decomposition of organic material.

Multi-Gen Worm Mix contains worms in all generations (babies, juveniles, breeders) as well as the essential “composting associates” (beneficial bacteria, microbes, fungi) which drive the decomposition of organic waste.

Bait Worms

Bait Worms

Our bait worms are red wigglers that get special treatment in order to fatten them up to bait-size: they live in shallow trays with a monitored population in order to ensure that they have plenty of room to grow.
