If you're already into outdoor or indoor worm composting, then why not make the most out of your worms? You can actually use your worms (whether these are red wigglers or nightcrawler worms) than just using them for composting purposes. They're not only good when it comes to breaking down the decomposing (recycling) organic wastes that you've accumulated at home, they can also be used to make money out of. They are that handy, multipurpose, and valuable to have. So try raising earthworms and get to reap the full benefits to breeding these earth wonders.
Sure you can make a profit out of raising red wigglers or nightcrawlers but don't even think about making slaves out of these creatures. They can be very versatile but they're living things too. They might have been born without eyes nor ears, but they can very much feel the things around them (they rely on vibrations) whenever something isn't right.
So how do composting worms become profitable? Well, aside from having to sell the worms per se, you can also market their castings (also known as worm poop, manure, or compost). Worm castings are said to be the richest kind of fertilizer that has been made organically. And since worms only consume nothing but natural materials (take for example your fruit and vegetable peels, coffee grounds, newspaper strips, crushed egg shells, grass clippings, etc.), they're only likely to produce and excrete natural substances that are packed with nutrients.
So having mentioned that you can sell your worms as is, the best thing that you can do is to care for them the right way (so that they may be able to grow at their healthiest). Healthy worms attract potential revenue. Fishermen will be going to you for their daily supply of fish bait, while other dealers will come to your for their buy-and-sell business. Dealers typically buy worms from other suppliers, so that they won't have to deal with the raising and breeding part of vermicomposting. What they will do with these worms is to offer them to other commercial breeders, to laboratories (those who might need it for experiments), and to aquariums (to be used as a source of food for the aquarium pets).
Now if you might have questions as to how to maintain worm farms at home, you just have to be able to provide your worms a secure and comfortable home. When you're raising earthworms, always make sure that they're provided with a composter that is well-ventilated, and has a good drainage system. Also prepare a moist bedding for them, as well as some organic scraps that they can feed on. Check on them once in a while, and make sure their castings are harvested; and that their bin is cleaned and replenished with new bedding and food. When you keep this up, your worm venture will become very successful.
