As rise and homes start to feel stuffy, many Brits are choosing to with their open. But experts are warning that it could come at a cost.

According to the experts at , open are basically an invitation for to come inside, especially during warm and rainy spells. "With turning both warm and wet, are becoming more active, and open windows at night create an easy entry point," said a spokesperson from My Home Improvements. They added: "We always recommend using window screens or restrictors during spring to keep out, especially when lights are on and you're fast asleep."

While spiders usually avoid people, an open window gives them a direct route indoors. Once inside, they can hide under beds, behind curtains, or even wander across your sheets.

Moths are another common issue. Attracted by bedroom lights, they often fly in and end up on clothes, bedding or even pillows.

But it's the biting insects that can be most annoying. Mosquitoes and midges thrive in warm, wet conditions, and spring showers create the perfect environment.

Once inside, they buzz around at night and leave itchy bites that can keep you awake.

But it's not just insects that come with open windows. There's also more noise.

Birds, barking dogs, traffic and late-night revellers can all disturb your sleep in the early hours.

And there are safety concerns too. An open or forgotten window, especially on the ground floor, could be an easy opportunity for burglars.

The experts suggest a few simple tricks to keep cool without the unwanted visitors:

• Install insect screens or clip-on mesh to stop bugs coming in
• Use window restrictors to allow some air without opening them fully
• Turn off lights or use blackout curtains to avoid attracting moths
• Air out your room earlier in the evening, and keep windows closed at night
• Spray the edges of windows with natural repellents like peppermint or citronella

A spokesperson added: "We understand people want to keep cool during spring nights. But with the current mix of humidity and rainfall, there's no question, bugs are on the move.

"If you're sleeping with your window wide open, you're also sleeping with your guard down."
