House flies have a reaction time of about 30 milliseconds—that’s why they always dodge your swat. But they also have compound eyes with 4,000 lenses, which means they see you coming in slow motion. Don’t feel bad; you’re just slow. And finally, flies don’t actually bite you (that’s the horse fly). The house fly just wants to hang out and vomit on your toast. So show them the door—literally.
Now go reclaim your kitchen. And if you see a fly doing a victory lap while you read this? Get the vinegar. Or the cat. Cats are surprisingly good at catching flies. They just look at you afterward like, “You’re welcome, idiot.”
