As a starter, for those who may be concerned, white worms look like human pinworms, but cannot successfully infect a human due to the low temperature requirements of this worm, and to the best of my knowledge, they do not carry any pathogens as can be gotten with tubifex worms.

First, you need a place that can hold a temperature below 70 degrees F. Second you need a starter culture. (The culture comes second since at above 70 degrees your worms won’t do well at all). A temperature between 55 and 65 is best if you expect them to reproduce. I prefer to use a Styrofoam box, like a fish box (with lid), since the box will help stabilize the temperature, and the lid maintains darkness which they demand or (otherwise they will hide). An unheated integral
garage, an old basement refrigerator set to as high as you can without turning it off, or some other “cold” spot in the house works well. I have heard schemes for raising white worms at above 70 degrees using sponges and water evaporation to keep them cool, but never tried it.

For a medium, I find that Magic Worm Bedding, available at Wal-Mart ...
