Here’s the thing: fruit flies are scent hounds, but for rot. They don’t care about your perfect apple. They want the bruised, forgotten, slightly smooshed one hiding behind the coffee maker.
That overripe tomato you swore you’d use? Yep. The empty wine bottle you didn’t rinse? Oh, absolutely. They can smell a single fermenting drop from across the room. It’s a superpower, and it’s annoying.
And here’s the kicker: they love drains. Your clean-ish sink is a five-star resort for them. Gunk, soap scum, that one noodle from Tuesday? That’s a buffet.
Your Groceries Are a Trojan Horse
You bring home a beautiful bag of peaches. They look perfect. You put them in the bowl, feeling smug. Congratulations. You just imported a fruit fly nursery.
Fruit fly eggs are tiny—like, dust-size tiny. They hitchhike on the skin of produce. The grocery store is basically their Ellis Island. You can’t see them, but they’re there, waiting for the warmth of your counter to hatch.
So by the time you see one adult fly buzzing around, there are already a hundred babies partying inside that banana. You didn’t invite them, but they came with the brie.
