Commercial worm farms are a type of business that breeds and sells worms for composting and bait, or sells worm castings for fertilizers. A business can be small or large as preferred by the individual running the business, and can grow over time. Building a commercial worm farm requires starting up the business and breeding the worms well enough to start bringing in sales. Customers typically include individuals that have organic gardens and fishermen that need bait and prefer the use of live worms.
Never add pineapple to the bin or it can kill the worms. According to the Worm Farm Guide, worm farmers should avoid pineapple, animal products, citrus fruits, green grass and acid fruits because the items either kill or repel worms.
Write a business plan. Obtaining the initial funding for the business requires a plan of action, estimate costs and proposed profits. Work out all of the details of the business in the business plan.
Obtain necessary funding. While a commercial worm farm is not the most expensive business venture to start, getting a small business loan is necessary to get the business started and running before sales are possible.
Fill out any legal paperwork necessary. A commercial worm farm is a business and needs all of the state and federal tax paperwork filled out. Specific paperwork and business requirements vary by state, so look up the necessary new business paperwork on the state website.
Obtain bins for the worm farm. The number of bins will differ based on the size of the business. A new, small business might start with two plastic bins and work up from there. One bin contains the worms, the other is on the bottom to catch run-off from the first. Make holes in the top bin and place it so that it is inside the other bin and any run-off will fall through the holes and into the second bin.
Put pebbles into the bottom of the bin with holes. Cover the pebbles with newspaper and then add a layer of soil to the top. Add a small amount of water to moisten the soil.
Add worm food. Worm food is stale bread, egg shells, cardboard and vegetable peels. This is added to give the worms something to eat to start with. Add food as necessary when there is space in the bin, but never push down on the materials in the bin to prevent crushing the worms.
Add the worms to the bin and cover with a lid. Worms dislike light, so the bin lid is used to keep it out. Worms will procreate as long as they have food.
Once there are enough worms available, sell the worm castings or worms, as preferred.
