It's not like you've been intentionally inviting them over for dinner, so what's the deal? The truth is, fruit flies can emerge from even the tiniest sources of moisture and decay. Think about it like a tiny little house party - all they need is a warm and cozy spot to set up shop, and they're good to go!
For example, have you ever left a forgotten banana on the counter for a day or two? That's like putting out a welcome mat for fruit flies. They can detect even the slightest hint of fermentation, and before you know it, they're sipping on that banana like it's a fruity cocktail.
