Readers ask: Do flies come from dead animals?

They are also attracted to plants that give off the smell of rotting meat and as such, can be a pollinator for those plants.

It is closely associated with rotting organic waste, including dead animals and faeces. It’s no surprise they’re commonly known as “filth flies”. After laying eggs, maggots will hatch out and eat their way through the decaying organic material before pupating and then emerging as an adult fly a few days later.

Where do flies come from when someone dies?

Blow flies lay their eggs on recently deceased animal corpses. The eggs quickly hatch into maggots which consume and break down the corpse.
