People sleeping with their windows open at night have been urged to buy one device which experts at My Home Improvements say will prevent an "easy entry point" for insects. The company says now that the weather is warm and wet, critters are "becoming more active". The firm adds: “We always recommend using window screens or restrictors during spring to keep unwanted pests out—especially when lights are on and you’re fast asleep.”

Arachnids are also a problem, as My Home Improvement highlights that, even though spiders typically avoid human contact, open windows offer a direct route inside, where they can seek out dark corners, bedding, or spots under furniture. Once inside, they do not always stay there, and it is "not uncommon for them to wander across beds at night". The company says: "According to experts, while it's theoretically possible for a spider to enter your mouth during sleep, the likelihood is extremely low.

"Spiders are generally deterred by the vibrations and sounds produced by sleeping humans, making such incidents highly improbable."

Moths are a common issue, and are attracted to bedroom lights.

They will happily fly in and circle lamps or settle into clothes, bedding or on your pillow, homeware experts say.

They add: "Warm air and standing water from spring showers are all it takes to bring out the mosquitoes and midges. Once inside, they buzz relentlessly and leave behind itchy bites.

"They're most active during the humid nights the Met Office has warned of this week, making unprotected windows a major risk.

In addition, with more people out late and wildlife becoming active at dawn, noise levels rise sharply in spring, and open windows invite it all in.

"Birds, passing traffic, barking dogs or pub crowds can all ruin a good night’s rest," My Home Improvement says.

"There’s also the issue of security: an open or forgotten window makes an easy target for opportunistic burglars, especially in bungalows or ground-floor flats."

Homeowners have been told to consider the following options:

• Installing magnetic or clip-on insect screens

• Using window restrictors to allow airflow without a full opening

• Turning off bedroom lights or using blackout curtains to reduce insect attraction

• Keeping windows closed overnight, and airing the room before bed instead

• Spraying window edges with natural bug deterrents like peppermint or citronella
