Soldier flies are good for compost piles/bins, especially if you throw protein scraps in it. If I recall the larvae supposedly bite, these aren’t like regular house fly maggots. The adult flies are harmless and live only a few days. They sort of look like little black bees more than house flies.

Thx. I wondered what those bee looking flies were. We have them here. They mostly just buzz around and don’t really bother you like regular flies.
