Make Your Own Slug Nematodes

In my compost bins, slugs (and, for that matter, woodlice) seem to do
just as good a job as worms at consuming and excreting what I put in.
Some of the slugs are real beauties - all shiny and black, or
fluorescent orange - and often 3+" long. If I find any in the garden I
usually transfer them to one of the bins, where they can live for the
rest of their lives in total luxury.
