Southern porches and diners swear by this quirky trick: Fill a ziplock bag halfway with water, drop in 5-10 shiny pennies, and hang it near doorways. The theory? Flies' compound eyes get overwhelmed by light refracting through the water and reflecting off the coins—like disco strobes for bugs. Some claim it works better with added aluminum foil strips for extra sparkle.
Pro tip: Replace the water weekly to avoid mosquito breeding (ironic, right?).
While science hasn't fully endorsed this, many say it reduces fly loitering by 30-50%. For serious infestations, pair it with fly traps or herbs like basil.
Bonus: It doubles as a redneck wind chime! Just don't blame the pennies if flies crash your BBQ—they're stubborn party crashers.
