Worm Composting Canada

Welcome to WormComposting.ca

Worm Composting Canada is a small vermicomposting business based in Waterloo Region (Ontario, Canada). We currently sell Red Wiggler Worms (Eisenia fetida) for worm composting, fishing and live food. We have a major focus in our local region - Kitchener, Waterloo, Cambridge and Guelph, Ontario - but are also happy to ship our worms elsewhere in Canada. If you happen to be based in the United States, the good news is that we've partnered with a fantastic supplier south of the border, and thus can easily fill U.S. orders as well. Please contact us for more information.

Just so you know, worm composting is much more than just a business for us here at WCC - it is an all-consuming passion! Aside from selling worms and supplies, we hope to share this passion with as many people as we possibly can! To learn more about us and our vision - be sure to check out our About Us page.

*** IMPORTANT UPDATE May 2023 *** - Unfortunately, the business is shutting down this season. There is currently a limited supply (30-40 batches at most) of Easy Worm Mix - along with a selection of bins and commercial bag systems (and various other products) available as of early June (pick-up in Waterloo Region only). If you are interested in learning more, please reach out via this new contact page. Thanks very much!

As of early June, I should have: – 30 to 40 Easy Worm Mix starter cultures (they will come in 5 gallon HDX bins) – […]

Simple In-Ground Bucket – Late June Update

A few days ago I checked on my “Super Simple In-Ground Bucket Worm Bin“. Normally this would be a system I would leave in the ground for at least a couple of months, but I want to make this an educational project so I decided to yank it out of the ground and really see […]

“Outdoor Grade” Easy Worm Mix Explained

SHORTER VERSION – The “outdoor grade” Easy Worm Mix is a larger volume (~ 18 litres) of living material and worms harvested from outdoor beds. It tends to have a lower density of worms-per-unit-volume (the original mix was usually around 10-12 litres), including different kinds of worms, and a more diverse ecosystem. It is far […]

Simple Breathable Bucket – 06-13-20

Back at the beginning of June I wrote about my “Super Simple Breathable Bucket Worm Bin”. The idea was to demonstrate that a bag of “outdoor grade” Easy Worm Mix can in fact be used to start up an indoor system. I decided on a “breathable bucket” (instead of a more typical worm bin) because: […]
