Many worm farms also supply vermicompost (a natural compost produced by using worms to speed up the decomposition of waste organic matter) and wormery kits (used for composting) to retailers such as garden centres.

Some worm farms supply live worms and wormery kits directly to anglers, reptile keepers and gardeners, and to organisations such as schools.

Worm species typically bred on commercial worm farms include dendrobaena, lobworms and tiger worms, which are all earthworm varieties commonly used for composting or as fishing bait. Some farmers also breed maggots (used as fishing bait) and mealworms (used as feed for chickens, wild birds and reptiles).
