EUROPEAN NIGHTCRAWLERS

Common Name:
  • European Nightcrawler
  • Belgian Nightcrawlers
  • Euros
  • ENCs
  • Super Red worms
  • Big Red Worms

Scientific Name:
  • Eisenia Hortensis


European Night Crawlers are fast becoming a favorite breed for the worm farm. In fact, some worm industry leaders predict that someday European Night Crawlers (ENC) will become more popular than Red Wiggler Worms. Euros are a great pick for vermicomposting, using worms to compost. 

European Night Crawlers are dark pink or red in color and grow to about twice the size of red worms.

Like red worms, the Euro is easy to raise and reproduce quickly so they are a good pick for both first timers and experienced worm farmers. Euros are pretty hardy, love table scraps, and grow quite large. If you plan on raising bait worms the Euro is a perfect choice.

So whether it is composting, raising bait worms, producing worm castings, or simply enjoying an eco-friendly hobby it's hard to beat the European Night Crawler when it comes to stocking your worm farm. But don't rush out and buy a bunch of ENCs without first learning more about them. Our European Night Crawler facts page will tell you everything you need to know to raise ENCs.
 
Advantages of European Night Crawlers 
Euros possess many traits which make them perfect for worm farming. Among the large worm breeds, the ENC is the most tolerant of temperature fluctuations and environmental changes. They definitely are more hearty than the African Night Crawler. If you want to worm farm in northern climates and want large worms the Euro is right for you.  
 
European Night Crawlers dig deeper than red worms, however, they are still considered top feeders. In other words, they thrive closer to the surface layer of top soil; close to the decomposing vegetative organic matter. Euros prefer just about any matter. Decaying leaves, grasses, wood and animal manure are all favorites of ENCs.

Euros have a good appetite making them ideal for the compost bin and nice worm casting (a.k.a. worm poop) producers. This breed gets much larger than red worms, getting up to 7 inches long and as thick as a pencil.  However, despite their size, they eat a little less than their red worm cousins.  Some estimates say the European Night Crawlers eat half their body weight each day.

European Night Crawlers are also colony dwellers, they don't mind bumping into each other in the worm bin. Close quarters living also makes them quick breeders and an ideal breed to raise in your worm farm. Just remember, if you want to fully develop Euros into outstanding bait worms they need plenty of room to grow large.

ENCs reproduce rapidly, but not as quick as red worms, but still fast. New hatchlings become mature breeders in an average of about 13 weeks. European night crawlers produce an average of a little over 1 cocoon a week. And from each cocoon, an average of about 1.5 hatchlings will emerge, so that means under ideal conditions you ENC worm farm will double in population about every three months. As with all worms factors that influence reproduction rates are food sources, temperature, and moisture conditions.     
 
Another big advantage of ENCs is their ability with tolerating a broad range of temperature extremes compared to other worms.  Typically Euros do best in temperatures between 60 F and 70 F (15 C - 21 c)  and can withstand temperatures from about 45 F to 80 F (7 c - 26).  When it gets below 45 F ENCs need to be protected from the cold. It's a bit riskier to keep ENCs in outdoors in the winter as they are colder sensitive than red worms. If you can maintain the Euros beds above 45 F give it a try. However, if you can move them indoors or to the basement start there. 

Euros also need protection from the heat. They will naturally burrow deeper into their beds when they get warm, or worse will try to escape the bin. Keep the beds under 80 F through the use of shade, careful watering, or experimenting with putting jugs of ice cold water buried in the bedding. If your worm farm is small consider moving them into the basement. 

Like other worms, European Night Crawlers breathe oxygen through their skin. To breathe they need a moist bedding material. Worm farmers report that ENCs need a bit more moisture than red worms. If you utilize plastic bins or a flow through worm farm your ENCs will likely be found deeper in the bedding material where moisture collects. In shallow bins or stackable bins make sure and closely monitor moisture conditions.   

The moisture in your bins helps breakdown bedding and vegetative matter by the microbes found naturally in worm beds. It is this liquefied mixture of decaying food and microbes that ENCs eat.
