Yes, apple cider vinegar can kill fruit flies—but not in the way you might imagine. It’s not like a magic spray that zaps them mid-flight.
Instead, ACV works like a sneaky trap. Think of it as a tiny, fragrant swimming pool they can’t resist—and can’t escape.
Fruit flies are obsessed with the smell of fermenting fruit, and apple cider vinegar smells exactly like a party to them. It’s their version of a fresh-baked cookie—irresistible.
The Science of the Sink
Here’s the cool part: fruit flies are actually attracted to the acetic acid in apple cider vinegar. That tangy scent tells their tiny brains “food nearby!”
Once they land on the surface of the vinegar, they don’t drown instantly. They kind of… slip in, get wet, and can’t fly out because the liquid breaks the surface tension.
It’s a bit like a tiny, fruity quicksand. They come for the smell, but they stay for the dunking. Effective, right?
