Here’s the “spawn” part that messes with your head. If you have a sealed bin and maggots appear, you probably brought the eggs in on accident. You didn't summon them. A fly sneaked in, laid her batch, and left you the surprise. You can blame the fly, but you can’t blame magic.
And if you think you've "killed" them all by cleaning the bin? Think again. The ones that survive crawl away to find a dry spot. They turn into pupae—little brown, barrel-shaped husks that look like mummified Tic Tacs. Inside, they're transforming into adult flies.
So when you see a new fly in your kitchen a week later, it’s not a new visitor. It’s the grown-up version of the maggot you forgot to flush. It came back to say "hello" and—you guessed it—lay more eggs.
So, How Do Maggots Spawn?
They don't. Flies spawn maggots. Maggots are the result of a fly making a very poor decision about where to drop her kids. They are the fly's dirty little secret, not a separate organism that appears from nowhere.
Next time you see them, just remember: that's the fly's parenting style. You get a pile of wriggling larvae, and they get a free babysitter (you). If that doesn't up your trash-sorting game, I don’t know what will.
