There are many ways in which people are wasteful, and throwing away food is one of them. Composting is a great recycling method, especially for those who like to grow their own fruits and vegetables, or have many potted ornamental plants.

7 Best Selling Worm Composters

Last update on 2021-11-28

One of the best ways to recycle food is by using earthworms. These are the best worms for composting because as they consume the food scraps, they produce what’s known as worm castings and worm tea. Both the castings and the tea are used on the plants that need nutrients to grow, but usually the tea must be diluted in water in an 1:1 ratio.

The darker the castings are, the better fertiliser, which is the whole purpose of the process. To turn your food leftovers into fertilizer using earthworms, you’ll need a composting bin. These come in many forms, shapes and colors, however not all of them are good for everyone.

Many users think that the best worm composter is one that can be easily manipulated, that has a good airflow, and requires minimum maintenance. For instance, many users like the bins on wheels as these can be effortlessly pushed around to find the best spot. There are many people who prefer a bin with one big chamber instead of one made of stackable trays that can be too heavy for some to operate.

Not everyone cares about the shape of the bin, but the size does matter as some households produce more food waste than others. Additionally, the size of your house should also be taken into consideration, as you’ll have a hard time fitting a big bin in a tiny apartment.

You should be warned that for most bins you have to buy the worms separately. In most cases, 1000 worms are enough to get you started. Giving them larger pieces of food will prompt them to multiply fast. Chopping the food will help them eat it faster, thus you minimize the risk of having a smelly bin. You’ll also have castings faster, if the worms eat faster.

Be warned that kids might really like having a composter to see how recycling works first hand. Since bad odors form mostly when there’s too much food or the wrong type of food ends in there, you can rest assured that your pets will ignore the newcomers.

As the very last tip, the stackable composters are great for beginners and households with very little waste. This is because most people start with just one tray and they add the others as the initial one becomes more and more full. Using one tray can also give you a good idea whether the process will work for you or not, in the long run.

Now, let’s have a look at a selection of the best or most popular bin models for composting.

1. The Squirm Firm Worm Factory 360 Bin

The box features a redesigned lid that can be turned into a stand for the upper trays when time to collect the compost arrives. Speaking of collecting the castings, depending on how many wigglers you have in there and the amount you feed them, you could expect up to monthly harvests. Each tray of this Worm Composter 360 has a capacity of approximately 4 gallons.

The Worm Bin 360 includes a 70 page book instruction manual with the pictures for beginners, as well as a 6″ by 9″ fridge magnet called “What Can Red Wigglers Eat?”. This magnet splits regular foods into sections based on how healthy they are for your worms to eat. You can easily drain the composter thanks to the built in collector tray and spigot.

You can set up the device in only a few minutes, by adding a few worms and kitchen scraps to the bottom tray. As the worms eat and the tray fills, they will move up for another food source and another tray should be added.

The very last tray has a ladder to help any wandering worm to find its way back up. Not many models have this feature, and there is a higher risk of creatures ending up dead when using those.

3. Version 2 Urban Worm Bag

Last update on 2021-11-28

At first sight this composting bin looks like a regular trash bin used by households producing a lot of waste. This is a good thing because you can have more compost as well.

The sack in which you throw the items to compost is made of Cordura Diner, a type of fabric used for high quality backpacks. Since the container is made of fabric, the airflow is improved when comparing this item to other bins.

One should also keep a bucket under the sack to collect the tea. Some worms might escape through the opening at the bottom since the string doesn’t perfectly close the sack, as it is too thick.

4. FCMP Outdoor Living Composter

Last update on 2021-11-28

This composting bin is good for smaller households because of its reduced dimension of only 2 trays and one container for the tea. If you find it too small for your composting needs, you can easily purchase extra trays. Keep in mind that each tray has a capacity of about 3 gallons.

Each tray is surrounded by a channel that has the role of controlling moisture and retain water. This feature ensures the bedding won’t dry around the edges. As a result you can be certain your red wigglers will always have an ideal home.

Like with most bins that have a tray design, this one too has holes at the bottom to allow your worms to migrate upwards when the current one is full. There are 40 angled holes giving the little creatures plenty of opportunities to crawl up.

The FCMP Outdoor has a 360 degrees airflow design achieved through aeration support points. A good airflow is crucial if you don’t want bad odors to form. Additionally, too much moisture in the air is also bad for the worms.

New owners are warned to use a worm barrier as to avoid them nesting at the bottom, in the valve and have it clogged. Dead worms can also clog it, so a screen of sorts is a must to prevent this from happening.

  • BPA free


  • Rather pricey
  • The legs make it difficult to move
  • Pretty heavy on its own
