There is nothing worse than being unable to open your windows on a sunny day because of flies swarming inside.

One man claims he has come up with a simple solution that will stop a plague on your house.

There's no flies on public-spirited Gerry Southgate, who has taken to the internet to share his solution with the rest of the world.

His method may work or may not help at all but his online post has been shared more than 50,000 times.

With that many people backing it it's sure to work, right?

Gerry posted his anti-fly solution back in June 2015.

He claims that hanging a plastic bag, half-filled with tap water and a few pennies, outside your back door will keep the flies – and wasps - away as they see it as a bees’ nest.

Gerry’s instructions in full are: “Half fill a plastic bag with water an add some pennies, (I put in 10) and hang it up outside your back door, hey presto, you have a fly free house!! It keeps flies, and wasps away as they see it as a bees nest!”

He says: “If you're having trouble with flies indoors in this lovely weather, try this, it really does work!

“Try it and if it works for you, (which it will!) share with everybody! Enjoy the sunshine!”
