Throw out overripe fruit immediately. Wash your bananas when you bring them home. That removes the eggs.
Empty your trash daily. Clean your drains with bleach. And don’t leave dirty dishes lying around. They don’t care about your schedule.
If you do this for two weeks, the party ends. No eggs. No maggots. No tiny drunk bards serenading your compost bin. Just peace.
So where are fruit flies coming from? They came from you. Your grocery store. Your compost. Your life. But now you know the secret.
You can beat them. Just remember: they are tiny, fast, and obsessed with your garbage. But you are a human with a jar of vinegar. You win.
