Why your house? Why not your neighbor's? Because you left a wine glass out. Or a compost bin open. Fruit flies are obsessed with the smell of fermentation. They can smell a rotting apple from over a mile away. Their antennae are better than a bloodhound’s nose.
Here’s the kicker. They don’t just eat fruit. They love vinegar. They love beer. They love kombucha. They even love the damp sponge in your sink. If it smells like it’s alive and breaking down, they want in.
And they multiply like crazy. A single female can lay 500 eggs. That means one lonely fly today is a squadron of 500 tomorrow. It’s a population explosion happening right in your trash can.
They Aren't from Outside (Usually)
People always ask: "Did they fly in through the window?" No. Not really. Fruit flies are weak fliers. They can't travel far. They came from that bag of potatoes you bought last week. Or the bananas you put in a bowl three days ago.
That's the crazy part. You are the delivery service. You bring them into your home in the egg stage. The warmth of your kitchen hatches them. Then the adults fly out and thank you for the hospitality.
