As Jaco Jansen (IDE) explains, black soldier flies contain lots of protein and better fatty acids than meat, along with iron, zinc and other minerals. He would like to put dogs on a diet of insects, which would make a difference of 50% in their meat consumption. ‘The black soldier fly is one of the best bio-converters in the world’. Jansen designed a compost bin that can be downloaded from the internet and printed using a 3D printer. The company Protix provides the fly eggs, the larvae eat their fill of compost and, after a week or two, you will have a collection of larvae. You can put these in the freezer and grind them up to make a healthy animal feed.
