Vermicomposting Bin

The Worm Wigwam

Vermicomposting Bin You will be amazed at how quickly and efficiently the Worm Wigwam converts your kitchen, yard, and garden waste to vermicompost.
For over 20 years The Worm Wigwam has proven to be an easy, efficient and economic way to convert organic waste to nutrient rich vermicompost. Our flow through worm bin is heated and insulated for year round use and can be conveniently located indoors or outside away from intense sunlight or other extreme weather exposure. The Worm Wigwam is easy to set up and because the worms do all the work, maintenance is easy too. This fantastic, worm powered machine comes with a three year guarantee.

Worm Bin This diagram shows how bedding and organic material are alternately layered in our worm bin by adding new layers on top. The worms continuously rise to feed on fresh layers, leaving a rich mixture of castings humus, worm cocoons, micro-organisms and organic material in varying stages of decomposition behind. This "worm free" vermicompost is easily sifted out with a quick turn of the crank and retrieved, ready for use, through the door at the bottom.

  • This is the best vermicomposting system that I have seen to date. Anyone interested in vermicomposting to accomplish organic waste diversion, education and/or research should definitely consider the Worm Wigwam. Two years later and ours are still diverting tons of organic waste from the landfill.

  • The Worm-Wigwam has kept me in the worm business. I was going to give it up because it was just too much work. Then I found the Worm-Wigwam and everything changed for the good. I'm now having the time of my life growing and selling worms without the intense labor I was going through before.
