Magnetic window fly screens that are described as 'completely bug proof' are available on Amazon starting from £26.99 each. They come in sizes from 120cm x 130cm up to 151cm x 180cm and can be trimmed for a perfect fit, with colour options of white and grey.
Easy Installation and Versatile Use
Unlike velcro-attached screens, these use strong magnetic tape around the edges, adhering to window frames without drilling. Installation takes as little as 15 minutes. They fit wood, plastic, and metal frames, and work on skylights, slide windows, and inward or outward openings, as well as caravan or car windows.
Removable and Cleanable
The screens can be removed for cleaning by vacuum or hand washing in soapy water. They attach firmly to prevent insects from entering while allowing fresh air and sunlight in.
For doors, magnetic door fly screens are available for £12.99, fitting frames 75-95cm wide with a split that snaps closed with magnets, allowing pets to pass through. A similar style is at Argos for £10, but cannot be adjusted.
Customer Reviews
One customer wrote: 'Just the job, I installed in 3 bedrooms... This product is a godsend. We can now have windows open at night without worrying about spiders and flies.' Another said: 'Value for money and has saved me in this hot weather... It’s easy to use and stays in place.' A third reviewer noted: 'Fits flush to window frame, so is completely bug proof. I've only given 4 instead of 5 as it was very time consuming & fiddly to put together.'
Some found installation difficult, with one stating: 'If I could give this minus stars I would. 3 hours and still can’t fit it properly.' However, another praised: 'Excellent product. Easy to fit... The net is really good quality... Have installed them across all upstairs windows so can sleep with everything open... And no creepy crawlies or flying insects.'
