Step 6 in How to Vermicompost
What Types of Vermicompost
Worms to Order
There are thousands of worm species. Most, however, are not suited for an indoor worm composting system. Common night crawlers and garden worms require very cool temperatures to survive and would do poorly if kept indoors at room temperature in a contained environment.
The two types of worms most commonly used for vermicomposting are Red Wigglers (Eisenia foetida) and European Nigh Crawlers (Eisenia hortensis).
Red Wigglers are also sometimes known as tiger worms, brandlings, or red worms. They're often sold in bait shops as "trout worms." Red Wigglers are a smaller worm (2-3" long) and are very active breeders.
European Night Crawlers are sometimes known as Dendrobaenas, Euros, or Belgian Night Crawlers. They are longer (3-5" long) and thicker than red wigglers, but smaller than most other night crawlers. Recently gaining in popularity, European Night Crawlers make slightly finer castings than other worms (and are also good for fish bait!). The finer castings can be easier to use in thin layers for houseplants or seedlings.
Either type of worm will work fine for your vermicomposting system, and will produce high quality worm compost for your garden or houseplants.
