Stop Flies Entering Your Home By Using A Bag Of Water And A Few Coins



Flies are just the worst and never more so when they work their way inside the home and the buzzing drives you mad and let’s not forget the disease they carry.

Bug sprays can make short work of them once they are in but it would be better if you can stop them getting in, in the first place.

One mom has revealed how she keeps them out of the home, and all you need is a Ziplock bag, water, and a few coins.

Taking to the Facebook group Hinch Army Cleaning Tips, she wrote: “Well after seeing someone post about the water-filled bag & coins to stop the flies I thought I’d give it a try.

“We normally always have about 5/6 small flies just flying about in the middle of the kitchen. So annoying.

“Well since the bag has been up, I haven’t had a single fly in the kitchen! Amazing.”

So does it actually work, and what is the science behind it?

The mom explained: “The water and the pennies create a prism that reflects colors, and also projects the image of the water.

“Flies don’t like water, and they don’t like the colors given off from the pennies.

“Flies have compound eyes so the bags look like a giant body of water to them, therefore they leave.”

The mom isn’t the first person to rave about the household hack.

Last year another mom said hanging a bag of water with some pennies in it is enough to deter the bugs.

Sharing a snap of her hack she wrote: “Seen a few posts about flies coming indoor as we’ve all our doors and windows open in this beautiful weather! A clear bag half-filled with water with a few copper coin’s in!



“Hang above the door/open windows, files hate it! I’ve not had 1 in days….

“Google it for the reasoning behind it I promise you I’m not crazy it works.”

And fellow group members were seriously impressed with the suggestion.

One wrote: “Amazing am going do this I hate they bloody flies getting in.”

Attesting the theory another wrote: “I do this, and it works, also, blow up a brown paper bag tie it up and hang it up, this will stop wasps, as they think it’s another wasp nest, and stay away (the bag should be medium in size).”

“It works I’ve 1 hanging over my back door which I leave open for my dogs, fingers crossed it keeps working all summer.” said another.

Explaining how the trick works the Holistic Horse confirmed: “It’s all in the reflection: When you have millions of molecules present, like in that clear, plastic bag, it creates its own prism effect.

“Flies have “compound eyes,” i.e. they see multiple images (whereas we see only one), but compound eyes cannot focus, so flies also see blurry images.

“To our winged little predator, that bag of water and its copper pennies appear, as one Google commenter described, like “a zillion disco balls,” reflecting lights, colors, and movement in a dizzying array.”
