How do I set up my Worm Composting Bin?
Starting your worm composting is easy. Our Worm Composting Bin Packages include everything you need (except the worms): easy-to-operate, stackable worm bins with cap, working trays, worm tea collector and base. We also include coir for worm bedding, two drain cloths, and an instruction booklet. Please note that our Worm Composters DO NOT include the
worms. You can purchase worms at local farms, or you can order them here from our website.
How does the Worm Bin work?
The design of the stackable worm composter Bin allows food waste to be put into the
starter tray with red worms, bedding and food scraps. As the worms finish digesting the organic
material in the starter tray, they will migrate upward into the tray above, leaving rich castings
(vermicompost) behind. The stacking tray feature allows users to add up to seven trays to meet
their growing compost needs. In full operation, a 5- tray Worm Bin system can house
approximately 10,000 to 12,000 worms (10 lb) who can consume up to 5 pounds of kitchen
scraps (no meat or dairy) or yard trimmings per day.
How do I choose which Worm Bin is right for me?
The Worm Bin comes in 3, 4 and 5-trays systems. Initially, you can start with a 3-tray
system and expand as you need to. You can purchase additional add-on trays here.

What kind of waste do the worms eat?
Do the worms like fibrous materials?
Worms are "vegetarians." They eat vegetables, leaves and fruit, but they cannot consume oils,
meat or dairy products. To encourage fast consuming, you may chop the waste finely before
adding it your Worm Bin.
Yes, they love them. Fibrous materials such as cardboard packaging, paper towels, egg cartons, and hair are all excellent choices.However, they need to be soaked in water so that approximately 20% to 25% of the material is saturated before adding it to the Vermihut tray(s).
How much can the worms compost?
It depends on the number of worms you have and the worm bin conditions. On average, two
pounds of worms can consume one pound of waste food in a day. The worms also reproduce
very quickly in ideal Worm Bin conditions.
Do the worms compost the foods completely?
In the beginning, the worms will eat just the fibrous materials/food. Then they move on to the
non-fibrous parts. It is best to wait until the worms have finished eating all the food before using
the compost they make. As long as you see worms near the surface, you can add more food
waste. This also helps ensure that your redworms stay in the compost bin and don’tend up in
your flower or vegetable beds along with the compost, since redworms will generally not survive
in typical garden soil.
Do I have too many worms?
No, not at all. The worms can regulate their population according to space and availability of
food. On average, one 3-tray unit can house about 6,000 to 8,000 worms.
What do we do during extreme weather conditions?
The worms prefer temperatures between 50° and 90° F. They can tolerate extreme temperatures.
However, in extremely hot weather, we recommend putting the worm bin in a sheltered place. In
extremely cold weather, we recommend moving the worm bin to a warmer place or wrapping it
with paper, bubble wrap, or a used blanket.
How can I keep the ants away?
You can place each of the four feet in bowls or trays of water. Ants will not cross water.
How can I prepare bedding without coconut fiber?
We recommend using shredded newspapers and compost or garden soil. Tear newspaper (no
colored pages) into strips approximately 1½ inches wide, mix newspaper strips with
compost/garden soil and moisten the bedding. When you squeeze a handful of bedding and a
few droplets water come out, and it forms a ball when you squeeze it, it's ideal. If a stream of
water comes out, the bedding is too wet.
When can I harvest the worm castings (vermicompost)?
This compost is now an excellent fertilizer for your plants. Empty the ready-to-harvest tray onto
Most of the worms will migrate to the upper trays for food once they've consumed the food in
the lower tray. Keep adding food and fibrous materials into the top tray. The bottom tray will
contain the worm castings (a.k.a. worm compost). When the material in the bottom tray is nearly
black, and looks like soil with only a few small chunks of mostly composted bedding matter, it is
time to harvest.
a plastic sheet. Rinse the tray with water. Since the rinsed water also contains rich nutrition, it
should be collected and used for your plants. Place this tray on top of the other tray(s). And the
cycle continues. Use the vermicompost on the plastic sheet to feed your plants, vegetables and
What will it happen if I don’t feed the worms for several weeks, say, if I go on vacation?
Don’t worry. The worm bin will be just fine for a whole month without your attention. Before
you leave for your trip, make sure you feed the worms a plenty of kitchen waste foods such as
fruit and vegetable waste. Leave the faucet of the worm bin open with a bucket underneath so it
can drain excess moisture. And or course, when you return from your trip, use this rich liquid
fertilizer as a special treat on your plants.
I notice some worms are turning white. Are these baby worms or is it a signal of a
These are not baby worms. Baby worms should have the same color as their parents. This type of
worm is called entrachyadides. They are not dangerous to the other worms. However, the
presence of this type of worm indicates the system is too acidic or the pH is too low. Add some
lime or oyster shell powder to adjust the system pH every month until the white worms are gone.
A pH meter is useful to help you determine the pH levels in your Worm Bin.
I notice some flies around the system. Is this going to be a problem?
Sometimes small flies may appear around your worm bin, but they are harmless. However, this
may indicate that the system has too much moisture or that there is too much food in the system.
To fix this problem, add some coconut fiber on top of the food, add a handful of lime, oyster
shell powder or dry materials such as dry shredded paper and cardboard. It may also be a sign
that you are adding too much food into the worm bin.
