Not only that, but they don't stink and won't go in your house, up your nose, or any of the other disgusting things that most flies do.

Don't worry about using those self-harvesting bins. It is easy to catch large larvae by putting some damp dog food in a colander. Fish like the larvae better than the pupa, and you get lots more.

It is a great use of what is left over after you fillet the fish. The run-off can be used just like worm tea, but there is enough in a large system that you might try to generate methane with it first in a digester.

The need to be warm, and they need natural light to mate. To date no one has bred them with artificial light, but it looks like lamps rich in UV might work. Grow lights (rich in red) did not work. They have been grown for years in green houses.
