Raising Nightcrawlers

Updated on April 6, 2015

Raising Nightcrawlers could be one of the most meaningful things to do especially when you are not busy. Aside from the fact that they are both good as composting worms and fishing baits, they are also very adaptable making it easy for you to raise them.

Just like the Red Wiggler worms, Nightcrawlers are heavy eaters of organic materials. In order to nourish them, you should provide them with a good environment and diet. For their home, you may use your old containers and tubs at home. Carefully place the bedding (coconut coir and peat moss are highly recommended) at around six to eight inches deep but before that, make sure that the bedding is moist. Night Crawlers have the tendency to escape from the bin if their environment is too dry or too wet. To check whether or not you have it right, try to squeeze the bedding and if out get at least 1 or 2 drops of water, then, that’s fine. Their environment should also have a maintained temperature of 55-78 degrees Fahrenheit though Nightcrawlers can still stand a temperature of 45 degrees.

PH level is also important. You have to have 6 to 7 PH level of acidity and to better achieve that, sprinkle powdered limestone in the bedding. You should always have PH meter on hand to monitor the bin. Foods are likewise vital for the Nightcrawlers. Give them organic foods but minimize dairy products and meat. Your kitchen scraps, fruit peelings, tea bags, newspapers, coffee grounds and chicken mash would do. If you are raising Nightcrawlers for the first time, it is advised that you do not yet give them foods for the first 3 days so they can adapt to their new environment.

Nightcrawlers multiply easily so it will not take a long time before you see the fruits of your labor. offers live earthworms for vermicomposting like European Nightcrawlers and Red Wiggler worms.They also offer quality organic gardening products from organic fertilizers, herbicides, pesticides to other green gardening supplies and equipments. Visit their site and browse their catalog to know more about their products.

      We do a lot of fishing and gardening in south Texas and want to raise worms to benefit both.

      We have now set up an old freezer under the trees behind the shed. We've drilled holes around the opening, just below the lid, and in the bottom corner for the liquids. I want line it with a durable garden fabric or other material, over the sub bottom. This bottom is to allow one direction drainage and make it easier for us to harvest worm tea, but something that will prevent the worms from getting down in that area. We also want it to be durable so it won't rot and doesn't have to be replaced often.

      What is recommended for this?

      Can they live outsite in 100degree weather if I keep them in the shade and damp?

      Hi Alex! Thank you for reading and voting up. Here's another hub that I wrote about making worm farms for nightcrawlers

      Are you raising them for fish baits or just for composting kitchen food scraps? if you're composting just to get rid of small quantities of kitchen scraps I would recommend you to use Red Wiggler worms. But if you want to compost a lot and want to produce a lot of worm castings, Nightcrawlers are perfect. You need to have a bin that is large enough for at least 6-8 inches of bedding as they eat faster and are deep burrowers compared to Red Wiggler worms. As for PH testing, any PH testing kit that you can get from a hardware or gardening store should do the job. :)

      Happy composting!

      Thanks for the informative hub - I'm more familiar with the nightcrawler for fish bait, but I'm interested in using it for composting as well. I was going to use some old plastic containers, but not sure what size to use. Do you have any recommendations for size of container based on how many worms? Also, you mention the temperature and pH of the soil are important - is there any particular equipment that you recommend using. Nice hub and voting up and useful.
