Our Guide to the Best Worm Compost Bins Under $100
Five worm compost bins under $100 compared on tray count, capacity, airflow and in-ground design, so you pick the right size for your kitchen scraps.
By Gardening Is Ezee Editors
11 min read5 products evaluated
A worm bin turns kitchen scraps into castings, and under $100 you can buy one of two designs. Stackable tray bins sit in a corner and let worms climb from tray to tray as food runs out. An in-ground bin buries in a raised bed and lets worms come and go through holes.
Size matters less than you would guess. Red wigglers work mostly in the top 6 to 8 inches of bedding, so a bin does not gain much from extra depth. What helps is surface area, airflow and a design that lets you harvest castings without picking out worms.
Keep temperature in mind too. Sources put the comfortable range at about 55 to 77 degrees Fahrenheit, and worms struggle above 90, so a garage or sunny balcony in summer is a bad spot.

Why Each Pick Made the Cut
Best Airflow Design1 of 5
VermiHut Plus 5-Tray Worm Composter on Amazon (opens in a new tab)
The most thoughtful lid and airflow design here: an M-board, a V-board with coconut fiber and anti-invader feet.
Best for
- indoor bins that stay odor-free
Our take
A 5-tray stack that adds an M-board for airflow, a V-board and a piece of coconut fiber built into the vented lid for moisture and odor control, and a set of shoes to keep other pests out. The base and liquid tray are one piece, so assembly is lighter.
Against the TOP XIAN it holds less but manages moisture and smell far better. Against the Blütezeit trays it adds the anti-pest feet and the one-piece base, which cuts leaks.
Choose it for a kitchen or apartment bin where odor and fruit flies matter. Skip it if you want the most capacity per dollar.
Key dimensions & specs
- 5 trays included
- M-board airflow
- V-board lid, coconut fiber
Pros
- Built-in V-board and coconut fiber manage moisture
- Shoes keep ants and crawlers out of the bin
- One-piece base and liquid tray prevent leaks
- M-board improves airflow through the trays
Cons
- Costs the most of the five
- Less total volume than the TOP XIAN
Best Capacity2 of 5
TOP XIAN 5-Tray Worm Composter on Amazon (opens in a new tab)
A 100 litre, five-tray bin that processes the most scraps of the group at a mid price.
Best for
- a large household's scraps
Our take
Five reusable black polypropylene trays with a combined capacity of up to 100 litres, stacked in a closed vented design that lets oxygen in and keeps odor in. Trays lift off one at a time so you can add worms and remove finished compost.
It has the biggest volume here by a wide margin, which suits a family. The tradeoff is that more bedding means a slower start unless you add a lot of worms. Against the VermiHut it lacks the moisture-control lid.
Pick it for a family that cooks a lot. Skip it for a small kitchen.
Key dimensions & specs
- 5 trays, 100L total
- Black PP plastic
- Closed vented design
Pros
- 100L across five trays is the biggest capacity
- Closed vented design keeps odor contained indoors
- Trays stack and lift off one at a time
- Black PP plastic is sturdy and light
Cons
- Needs many worms to fill that volume
- Basic lid has no moisture-control insert
Best Mid-Size3 of 5
Blütezeit 5-Tray Worm Composter on Amazon (opens in a new tab)
A 53 quart five-tray bin that balances capacity and price for an average household's scraps.
Best for
- a standard household
Our take
Five stackable PP trays with 53 quarts of capacity, air holes in each tray for ventilation and a design that is described as simple to stack. Titled as a starter kit, it is meant for indoor or outdoor use.
It sits between the 32 quart 3-tray and the 100 litre TOP XIAN, so it holds about twice the 3-tray at a modest premium. It lacks the VermiHut's extras.
Choose it for a family of two to four. Skip it if you need to save money or space.
Key dimensions & specs
- 5 trays, 53QT
- Air holes in each tray
- Stackable PP plastic
Pros
- 53 quarts across five trays for a family
- Air holes in each tray improve airflow
- Simple stacking makes setup quick for beginners
- Suits both indoor and outdoor placement in shade
Cons
- No built-in moisture-control lid like the VermiHut
- Larger than needed for one person
Best Compact Tray Bin4 of 5
Blütezeit 3-Tray Worm Composter on Amazon (opens in a new tab)
A compact three-tray bin with 30 litres of capacity, the easy first worm bin for one or two people.
Best for
- apartments and balconies
Our take
Three trays holding 8 gallons (30 litres) in total, with air holes in each tray for ventilation and a compact design for apartments and balconies. The titled starter kit is marketed for indoor or outdoor use.
It is the smallest tray bin here and is cheaper than the 5-tray models. The tradeoff is limited capacity, since a household with a lot of scraps will outpace it.
Pick it for a single person or a couple. Skip it if you cook a lot.
Key dimensions & specs
- 3 trays, 8 gal (30L)
- Air holes in each tray
- Compact footprint
Pros
- 30L fits a counter corner or balcony
- Air holes in each tray give ventilation
- Three trays are easy to manage
- Costs noticeably less than the five-tray bins
Cons
- Small capacity fills quickly with scraps
- Only three trays to rotate through
Best In-Ground5 of 5
Vego Garden 7 Gallon In-Ground Worm Composter on Amazon (opens in a new tab)
The only in-ground option: bury it in a raised bed and worms feed the soil around it directly.
Best for
- feeding a raised bed directly
Our take
A 7 gallon BPA-free polypropylene bin designed to sit in the ground of a raised bed, so worms process kitchen scraps and enrich the soil nearby. It is made for outdoor use and the injection-molded plastic is meant to last.
Unlike the tray bins it has no liquid collection and no trays to rotate, because the garden is the harvest. It is the cheapest here, and it needs no indoor space.
Choose it for a raised bed or garden where you want to feed the soil. Skip it for a kitchen or apartment, where a tray bin is better.
Key dimensions & specs
- 7 gallons
- BPA-free polypropylene
- Buries in garden bed
Pros
- Buried bin feeds the soil around it
- BPA-free polypropylene is made for outdoor use
- No indoor space or odor concerns
Cons
- Needs a garden bed to bury it
- No castings harvest or liquid collection
How We Built This Shortlist
Each pick was assessed across 5 criteria weighted for real-world use.
- Design type
- Tray bins and in-ground bins were separated first, since they suit different homes.
- Capacity
- Litres and quarts were compared to match each bin to a household size.
- Airflow and odor control
- Holes, boards and vented lids were compared for how well each keeps air moving and smell down.
- Moisture and leak handling
- Liquid trays, one-piece bases and lids were compared for how they manage water.
- Value under $100
- Capacity and design extras were weighed against cost.
What Matters Before You Choose a Worm Compost Bin
Key buying criteria so you get the right fit the first time.
Tray bin versus in-ground bin
A tray bin stacks vertically and gives you finished castings in the bottom tray, while an in-ground bin buries in a bed and feeds the soil directly. The first suits apartments and gives a harvest, the second suits gardens and needs no indoor space. Choose by where you live.
Total volume and your scraps
Volume decides how many scraps the bin can process. A 30 litre bin suits one or two people, 53 quarts suits a small family, and 100 litres suits a large household. Red wigglers work in the top 6 to 8 inches, so extra depth does not help.
Airflow and odor
Worms need oxygen, and a closed bin without airflow will smell. Look for holes in each tray, an airflow board or a vented lid. The VermiHut has an M-board and V-board, and the Blütezeit has holes in every tray.
Moisture control
Worm bedding should feel like a wrung-out sponge, and a bin that traps water will drown worms. A lid that wicks or absorbs moisture helps. Look for a lid insert, a drain or a liquid tray.
Temperature range
Red wigglers do best at about 55 to 77 degrees Fahrenheit and die when it passes 90. A bin in a hot garage in summer is risky. Place it indoors or in shade.
Worms are not included by default
Most bins are titled as starter kits but do not necessarily include worms. Buy red wigglers (Eisenia fetida) from a farm that raises them for composting, not garden earthworms or nightcrawlers. About a pound suits a standard bin.

- In-ground bin

For Apartment Dwellers Specifically
- Look for

- Spend more if
- You want a durable US-made frame or more trays. The VermiHut Plus 5-Tray Worm Composter is the top here, and the next tier adds the Worm Factory 360.
- Save if
- You only need a basic bin. The Vego Garden 7 Gallon In-Ground Worm Composter or Blütezeit 3-Tray Worm Composter covers that.
Before You Bring One Home
What worms do I need?
Red wigglers (Eisenia fetida), not garden earthworms or nightcrawlers. Buy from a farm that raises them for composting.
How many worms should I buy?
About a quarter to half a pound for a small starter bin and around a pound for a standard home bin.
What temperature do worms like?
Roughly 55 to 77 degrees Fahrenheit, according to extension sources. They struggle above 90.
How wet should the bedding be?
Like a wrung-out sponge, damp without standing water.
Does a bigger bin compost faster?
Not necessarily. Red wigglers work in the top 6 to 8 inches, so surface area and airflow matter more than depth.
Can I bury the Vego in any garden?
Yes, in a raised bed or garden soil. Keep it in partial shade so the soil around it stays cool.
