You’ll need:
- A clear plastic sandwich bag
- Water (fill it halfway)
- 3–5 shiny coins (pennies or nickels work great)
- A twist tie or string
Just drop the coins in, seal the bag tight (no leaks!), and hang it near any fly-prone area. That’s it. No smells, no chemicals, no zapping. Just a weird little bag of water doing its thing.
People Swear by It (I’m One of Them)

After I started using it, I told a couple of friends — skeptics, of course. But after trying it out at a weekend BBQ, one of them texted me, “I don’t know what kind of witchcraft this is, but I’m never using fly spray again.”
My cousin tried it in her garage. My neighbor hung one near her kitchen door. All reported the same thing: fewer flies, no effort.
Final Thoughts
It’s funny, isn’t it? With all our tech and gadgets and sprays, sometimes the best solution is the simplest one — like something your grandma pulls out of a drawer without explanation.
If flies are driving you nuts, try this. One plastic bag, a few coins, and a bit of string. That’s all it takes.
Thanks, Nana.
