Mums are hanging bags of water and coins on their windows to ward off flies & swear they haven’t had a single one since

AS SUMMER approaches windows and doors will be flung open across the nation in the hope to invite in some breeze.

However, doing this will often invite in some unwanted guests too in the form of pesky flies.

But fear not, as on thrifty mum has revealed how to keep them at bay, and all you will need is some water, some coins and a clear bag.

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 mum posted an explanation one person on the thread gave, which said: "The water and the pennies create a prism that reflects colours, 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 mum isn't the first person to rave about the household hack.

Last year another mum 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 post 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 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.”

One wrote: “Amazing am gny do this i hate they bloody flies getting in (sic).”

Attesting the theory another wrote: “I do this, & it works, also, blow up a brown paper bag tie it up & hang it up, this will stop wasps, as they think it's another wasp nest, & 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.”

And a mum's £4 cleaning trick will get your filthy washing machine drawer sparkling in minutes.
