This is the oldest trick in the book, and it works about 70% of the time—which, in wasp logic, is a home run. Open the window wide—all the way, not just a crack, because wasps are surprisingly good at geometry and will find the tiny gap. Then, gently coax the creature toward the fresh air using a magazine or a piece of cardboard. Think of it as a paparazzo guiding a reluctant celebrity into their limo.
If the wasp ignores your open window and instead buzzes your face, resist the urge to slap it. You’ll only end up with a sore hand and a very angry wasp. Instead, turn off the lights in the room and open a window in another room—wasps are naturally drawn to light, like teenagers to a phone screen. They’ll follow the glow right out, leaving you to mutter, “Yeah, that’s right, go back to your hive and tell your friends I’m a nice person.”
