A couple of weeks ago I wrote about using worms to create compost. The official term for this is “Vermicomposting” and the great thing about it is that it is clean and tidy and does not take up a lot of space. For folks that have small yards or live in apartments, this is ideal plus, if need be, vermicomposting can even be done indoors. Imagine composting in on your porch, a deck or even in your laundry room!
Now that I have you excited about composting with worms – and specifically red worms – I would like to provide you with instructions for building the cheapest worm bin imaginable. It is built out of commonly available supplies and is so easy even a novice handyman (handyperson?) can do it.

THE CHEAP AND EASY WORM BIN
Here are the materials you will need to build your worm bin.
Two 8 to 10 gallon plastic storage bins
Drill (with 1/4″ and 1/16″ bits) for making drainage and ventilation holes
About one pound of red wiggler worms
The bins should be opaque and not clear. This is because worms like to live in the dark and will not thrive if there is any light coming into their home. Also, although you could use larger bins, they will be too doggone heavy to lift once they are full of nicely composted worm castings. Stick with the smaller 8 to 10 gallon size. These will set you back about $5 each.
1. Drill about twenty evenly spaced 1/4 inch holes in the bottom of each bin. These holes will provide drainage and allow the worms to crawl into the second bin when you are ready to harvest the castings.
2. Drill ventilation holes about 1 – 1 ½ inches apart on each side of the bin near the top edge using the 1/16 inch bit. Also drill about 30 small holes in the top of one of the lids.
Note: You are going to need to build two bins although in the beginning, only one will be used.
3. Prepare some nice bedding for the worms by shredding some newspaper into 1 inch strips. Worms need bedding that is moist but not soggy.
Moisten the newspaper by soaking it in water and then squeezing out the excess water. Easier still, fill a spray bottle with water and spritz the shredded newspaper until it is nice and damp. This might take awhile because you will want to fluff it up as you go but it will prevent the worm bedding from getting too soggy.
4. Cover the bottom of the bin with 3 to 4 inches of the moist newspaper. Continue to fluff it up so that it is nice and airy. If you have any old leaves or leaf litter, that can be added also. Throw in a handful of dirt for “grit” to help the worms digest their food.
5. Add your worms to the bedding.
6. Cut a piece of cardboard to fit over the bedding, and get it wet. Then cover the bedding with the cardboard. Worms love cardboard and it will break down within months.
7. Place your bin in a well-ventilated area such as a laundry room, garage, balcony, under the kitchen sink, or outside in the shade. Place the bin on top of blocks or bricks or upside down plastic containers to allow for drainage. You can use the lid of the second bin as a tray to catch any moisture that may drain from the bin. This “worm tea” is a great liquid fertilizer that can be used right away on your indoor or outdoor plants.
8. Feed your worms slowly at first. As the worms multiply, you can begin to add more food. Gently bury the food in a different section of the bin each week, under the cardboard. The worms will follow the food scraps around the bin. Burying the food scraps will help to keep fruit flies away.
THE SKINNY ON WORM FOOD
What do worms like to eat? Worms are vegetarians. They like green stuff mostly and absolutely no meat and no dairy. That means no bones, no grease and no anything with grease. On the other hand, almost anything else that would normally go down the garbage disposal can go into your worm bin. Just don’t be surprised if you notice that some foods will be eaten faster than others. Worms have their preferences just like we do.
Worms LOVE this stuff
Breads & Grains
Coffee grounds & filters
Fruit & veggie peels
Rice & Pasta
Worms HATE this stuff
Worms LIKE brown stuff too!
WHEN THE WORM BIN IS FULL
When the first bin is full and there are no recognizable food scraps left, it is time to split the bin so you can begin the harvest.
Place new bedding material in the second bin and place the bin directly on the compost surface of the first bin. Bury your food scraps to the bedding of the second bin. In one to two months, most of the worms will have moved to the second bin in search of food. (Remember those little drill holes we made at the onset?)
Now the first bin will contain (almost) worm free vermicompost. There may be a few straggler worms left in the first bin. These can be gently lifted out of the bin and placed in the new bin or you can simply add them to your garden along with the new compost.
If you don’t care about creating a second harvest down the road, you can skip the step where you split the bin. The worm population will adapt to the amount of space and food available and things will remain stable until you decide to remove the compost and begin the process all over again.
|Worms are dying or trying to escape||Too wet||Add more bedding|
|Too dry||Moisten bedding|
|Bedding is used up||Harvest your bin|
|Bin stinks!||Not enough air||Drill more ventilation holes|
|Too much food||Do not feed for 1-2 weeks|
|Too wet||Add more bedding|
|Fruit Flies||Exposed food||Bury food in bedding|
A NOTE ABOUT THE WORMS
Here in the Pacific Northwest, you can gather your own red worms. All you need to do is to put out a large piece of wet cardboard on your lawn or garden at night. The red worms live in the top 3 inches of organic material and like to come up and feast on the wet cardboard. In the morning, lift up cardboard to gather your red worms.
Elsewhere, or if you don’t have a lawn or suitable garden, you can purchase worms. Be sure to ask for “red wigglers”.
According to Chris Benedict, a Regional Extension Specialist at Washington State University, an earthworm can consume about 1/2 of its weight each day. He says, for example:
If your food waste averages 1/2 pound per day, you will need 1 pound of worms or a 2:1 ratio. There are roughly 500 worms in one pound. If you start out with less than one pound, don’t worry they multiply very quickly. Just adjust the amount that you feed them in accordance with the size of your worm population.

THE FINAL WORD
Imagine how easy it would be to create organic compost for your garden without having to trek to an obscure corner of your backyard in order to carry your food scraps to the compost bin. Instead, why not let red worms eat your food wastes? In a matter of months and not years, you will end up with one of the best soil amendments out there, namely worm castings.
My thanks to Chris Benedict who provided inspiration and gave me permission to use his ideas and his photos in this article. In addition, he has provided this link for building a more advanced, wooden worm bin: Build a Worm Compost Bin.
