I don't know where you live. Most people buy European earthworms for their compost heaps.

It is reasonable to assume that European earthworms would be culturally superior to native composters because Europeans are superior to natives.

I live in the Western US where European earthworms are an invasive species. So, what I did was to go into a local wilderness area. I found a place with rich loamy soil and filled a small jar with the soil. I used that to start my compost heap. I now get rich loamy compost instead of the claylike compost from earthworms.

You might also contact a local university to find out about native composters.

If you happen to live in Europe ... then by all means use the friggin' local earthworms. Imported composters have a habit of become invasive.
