Plenty of them, a real annoyance. But this got me to think: As those buggers are one of the fastest reproducing insects known and thousands can survive and thrive on a small pile of cow manure,

= Why not farm them on a commercial basis and turn them into animal-feed?

The question is: Of how much carbo-hydrate and protein and other nutrients do they consist of, as a percentage of their body weight? But just by looking at them, it seems to me they are made out of wings, legs, skin and bone = bulk!

Anyone in the know?

Thanks & cheers.

RT did a special on future foods, one item was using house flies as a human food source: http://www.youtube.com/watch?v=GhPbgNOYqhg

I will not be the first to sign up for the "Fly Burger" though...

On a more realistic note; Soldier Fly are the way to go, for your purposes. They are easily harvested, they do not bite or harbour pathogens, they are said to have pheromones which drive away house flies, and they do not buzz around much (so much less annoying than house flies).
