I used to raise mealy worms for Bluebirds to save money. I will look this up and see where to get cultures and more about it.

Probably the best easiest place to obtain a culture is a local fish-keeping club, if you have one available near you. I currently have 6 cultures going in plastic Sterlite "shoe boxes".
White worms require temperature of 70F or less to really thrive and will start to die off if the temp gets to 85F. I keep my cultures on the basement floor and they do well.
Coco fiber - which is used as bedding for reptiles - is probably the best growth medium. Sterilized potting soil is also an alternative. I've used both and prefer the coco fiber.
Some folks suggest placing moistened bread (the food) on top of the bedding. I don't like doing that, as it tends to mold pretty quickly ... often before it has been consumed. Instead what I do is dig a hole to the bottom of the container and place ground up, stale bread products in it, moistening them after they have been placed and then covering with bedding. This prevents mold and avoids any smells that might occur as a consequence of decomposition. Since the containers (except for their lids) are clear, they can be easily checked by looking up through the bottom to see if the worms have consumed all their food and whether it is time to replenish.
To harvest the worms I place a container on an old heating pad set on "High" for 30 - 60 minutes. This drives the worms to the surface and up on the sides where they can be easily removed with a fork or your finger.
