How to Make an Indoor Worm Bin?
Worm composting is a great way to recycle organic waste and turn it into nutrient-rich soil amendments. Not only is it good for the environment, but it’s also great for your garden! In this blog post, we will show you how to make an indoor worm bin using a plastic storage bin with a tight-fitting lid. We’ll also give you step-by-step instructions on how to set it up and get started. So what are you waiting for? Let’s get composting!

DIY Worm Composter Step-by-Step Instructions
- A plastic storage bin with a tight-fitting lid
- Drill or poke holes in the bottom of the bin for drainage
- Cut a piece of screen to fit over the top of the bin
- Soak some cardboard in water and wring it out so it’s damp but not wet
- Put the cardboard in the bottom of the bin, and add some soil on top
- Add your worms (you can get them from a friend or online)
Step One: Drill or Poke Holes in Bottom of Bin for Drainage
The first step is to drill or poke holes in the bottom of the storage bin. This will allow any excess moisture to drain out, and will help keep your worms healthy. If you’re using a drill, we recommend using a bit that’s slightly smaller than the diameter of your worms. This will help keep them from escaping.
Step Two: Cut a Piece of Screen to Fit Over Top of Bin
The next step is to cut a piece of screen to fit over the top of the bin. This will help keep fruit flies and other pests out, while still allowing air to circulate. We recommend using a fine-mesh screen so nothing can get in or out.
Step Three: Soak Cardboard in Water and Wring It Out
Now it’s time to soak some cardboard in water and wring it out so it’s damp but not wet. This will be used as bedding for your worms. Once it’s damp, put it in the bottom of the bin and add some soil on top.

Step Four: Add Your Worms
The last step is to add your worms. You can get them from a friend or online. If you’re getting them from a friend, make sure they come from a healthy worm bin. Once you have your worms, add them to the bin and cover with the lid.
Now that you’ve set up your indoor worm bin, it’s time to start composting! Here are a few things to keep in mind:
- Your worms will need food (organic waste) to eat. Things like fruit and vegetable scraps, coffee grounds, and eggshells are all good options. Avoid meat and dairy products, as they can attract pests and make your bin smell.
- You’ll need to add more food scraps every few days. Start with a small amount and increase as you go.
- Every few weeks, you’ll need to harvest the compost from your bin. This can be done by simply removing the lid and scooping it out with a shovel or spade.
- Once you’ve harvested the compost, you can use it in your garden or give it away to a friend.
What to Feed the Worms?
You can feed your worms just about any organic waste, including fruit and vegetable scraps, coffee grounds, tea bags, eggshells, and even shredded paper. Avoid feeding them meat or dairy products, as these can attract pests. You should also avoid feeding them anything that has been treated with chemicals or pesticides.

Expanding your worm bin
As your worm bin starts to fill up with compost, you can add additional bins on top. Simply drill or poke holes in the bottom of the new bin for drainage, and stack it on top of the old one. The worms will eventually make their way up to the new bin as they consume the food in the old one.
Harvesting Worm Castings
Worm castings are a nutrient-rich soil amendment that is perfect for your plants. To harvest them, simply remove the screen from the top of the bin and scoop out the castings with a shovel or spade. Be sure to put the screen back in place so that your worms don’t escape!
What The Best Worm Foods for Your Soil?
Composting worms will eat just about anything, but there are some foods that they love more than others. Here are a few of our favorites:
- Fruit and vegetable scraps
- Coffee grounds
- Tea bags
- Eggshells
- Shredded paper
