Here’s the play-by-play. A female fly lands on her chosen gross spot. She uses her ovipositor (fancy word for egg-laying tube) to deposit a cluster of tiny white eggs. Each batch has about 100 to 150 eggs. She’s not messing around.
She lays them in batches, often over several days. That’s why you might see them swarming a single spot. They’re taking turns. It’s like a grotesque timeshare.
Within 24 hours, those eggs hatch into maggots. Maggots are basically eating machines. They don’t have legs or eyes; they just wiggle and eat. And they grow fast. In a few days, they turn into pupae, then adult flies. The cycle repeats.
What Attracts Them? (Spoiler: You)
You might think you’re clean, but flies find you. Open food is a beacon. Leave a slice of pizza out for an hour? That’s a fly’s dinner invitation. They can land on it, decide it’s not perfect for eggs, but still contaminate it with bacteria. Fun, right?
Sweet smells are also huge. Overripe fruit, spilled soda, even wine. Flies love the sugar rush. They’re like drunk college kids at a party, but with more wings and less shame.
And finally, warmth. Flies are cold-blooded, so they love warm spots. Your sunny kitchen window, the top of your fridge, or near a compost bin. It’s like they’re on a vacation to Maggot Beach.
