You walk in and out a hundred times a day. For a fly, your door is a revolving buffet door.
Think about it. You open the door to grab the mail. That’s a full three seconds of open season. A fly sees that as a golden ticket.
They don’t barge in. They drift. Like tiny, six-legged ghosts on a summer breeze.
Windows: The Glass Illusion
We assume windows are solid barriers. Flies laugh at our assumption.
Check your window screens. Are you sure they’re perfect? One microscopic tear looks like a grand canyon to a fly.
Even a gap the width of a dime is a wide-open highway. They squeeze their bodies through spaces you wouldn’t believe possible. It’s like fly yoga.
