I have to say it: you are the fly’s best friend. Every time you open a door, you create a slipstream—that little rush of air that sweeps bugs inside. A fly can hitch a ride on that air current faster than you can yell, “Shut the door!”
Think you’re safe because you don’t leave the door open for long? A fly entering your home takes about 0.12 seconds. That’s faster than your blink reflex. Surprising fact: flies can see 250 frames per second (humans see about 60), so they time their entrance perfectly—like a ninja with six legs and a bad attitude.
