ON a hot sunny day, there is nothing better than cracking open all the windows and doors and letting the sunshine flood in.

There's just one problem - this inevitably means your house will be invaded by flies.

That said, shoppers are singing the praises of B&M's door screens for keeping pesky insects at bay.

And the best part is, it'll only set you back a quid.

Posting on the Facebook group Extreme Couponing and Bargains UK, one happy shopper shared a photo of her door screen in action.

She wrote: "Pleased with my purchase. Stops the insects flying in the house!"

So how does it work? Well, the bargain screen has magnetic strips running along the seams so all you have to do is place it to the back door.

Once installed, the tiny holes in the door frame will prevent bugs from flying in while you make the most of the cool breeze.

What's more, the foolproof product - which is available in black, white and grey - would ordinarily set you back £2.99 but has been reduced to £1 in the sale.

Needless to say, other members of the group are desperate to get their hands on the bargain buy.

One replied: "Need this in my life! I hate flies and now my 2 year old constantly screams at them."

Another added: "I bought one from B&M last week, it's amazing."

Tagging a mate in the comments, a third gushed: "We need this!"

For more bargain buys, people are raving about Wilko’s tray fryer that can fry six items at once & only costs £20.

And this woman instantly brightens dingy kitchen for just £20 by painting tiles and using sticky back plastic on the counter tops.

Plus this cleaning fanatic got rid of grim stains on her mattress using £1.50 Home Bargains spray.
