Ok, i'm intersted in this very subject, as a way to supplement my fishes diet.
I can understand the principle of the making of the bin and stuff. Lots of info on the likes of Youtube etc
What i cant seem to work out, though, is what happens should other types of fly get there 1st, and all you end up with are maggots, and, a few days later lots of (say) bluebottles annoying the heck out of you?
