Fly screen buying guide

Updated: October 2026

A warm evening in a UK kitchen usually ends the same way. You prop the back door, or you crack a bedroom window, and the flies arrive before the room has cooled. A fly screen buying guide should settle the opening first, then the fixing, then whether the listing prints a mesh grade. The ten screens in our [Fly screen comparison](/hub/hedges-and-privacy-screens/fly-screen) run from a £2.56 tesa sheet to framed kits around £27 on amazon.co.uk, in this snapshot from 20 October 2026. Products Compared read those listings and the saved UK review lines. We did not run a lab test. A qualifying purchase can earn us a commission at no extra cost to you.

Start with the opening

You are choosing one of four types in this set, and they do not swap jobs. A door you walk through needs a magnetic centre-seam curtain: YRH at £7.99 (fixed 80 x 200 cm), EGNBU at £8.99 (up to 90 x 210 cm, 26 magnets stated), SMALUCK at £9.99 (fixed 90 x 210 cm), Flux Phenom at £18.95 (up to 80 x 200 cm, 52 magnets and 1 mm holes stated), or TheFitLife at £20.99 (doors up to 91 x 208 cm, 26 magnets stated). A window takes the £2.56 tesa sheet, the MOEGFY pack at £11.04, or a framed kit from about £23 to £27. The magnetic fly screen door page stays with the five curtains. The window fly screen page stays with the sheets and the kits.

Measure the frame, then read maximum or fixed

Measure the frame, not the glass. Take the width in three places and the height in three places, and keep the smallest of each. Read the listing as either a maximum or a fixed curtain. Up to 90 x 210 cm on the EGNBU means the frame should be no larger than that. A reviewer still found that curtain about 4 inches too long. 80 x 200 cm on the YRH is a fixed curtain. A SMALUCK reviewer says that 90 x 210 cm curtain cannot be trimmed to width, and Flyscreen Queen says not to cut a lightweight magnetic door screen because the magnets and the weighted hem sit in the mesh. If the opening is already wider than the curtain, reorder. The clean-frame sequence is on the how to fit a fly screen page.

What the mesh line is allowed to mean

Streme, a UK mesh supplier, defines standard insect mesh as 18 x 16 holes per square inch, which is the grade aimed at flies, mosquitoes, wasps and moths. The same guide defines genuine midge mesh as 30 x 20, and it says a 20 x 20 weave does not stop midges. None of the ten technical tables in this set print 18 x 16 or 30 x 20. Fine mesh on the MOEGFY nets, and 1 mm holes on the Flux Phenom bullets, are not that specification. If you need a named 30 x 20 mesh, these ten listings do not print it. Flux Phenom's 4.5 from 75,289 is the saved listing figure. It does not name the weave.

Fixing, price bands, and what it will not do

Adhesive hook-and-loop is the usual no-drill method, and a clean, dry frame is the instruction that shows up across the listings. Reviews on several door curtains, and on the MOEGFY nets, say the tape lifts in heat, on paint, or after a short time. Pins and thumbtacks are in the EGNBU, SMALUCK, Flux Phenom and TheFitLife boxes or bullets. Prices in this set, not a survey of every UK shop, sit in three bands. About £2.50 to £10 covers the tesa sheet and the YRH, EGNBU and SMALUCK curtains. About £11 to £21 covers the MOEGFY pack, the Flux Phenom and the TheFitLife. About £23 to £27 covers the three framed kits. Call a fitter for a wide slider beyond these maxima, or when an upper-floor restrictor is missing.

Common questions

Do I buy a door curtain or a window screen?
Buy a magnetic centre-seam curtain only for a door you walk through. Buy a cut sheet or a framed kit for a window. The five curtains in this set are the YRH, EGNBU, SMALUCK, Flux Phenom and TheFitLife. The window products are the tesa sheet, the MOEGFY pack, and the MiLeJu, BITOYO and NeatiEase kits.
Do I measure the glass or the frame?
Measure the frame, width and height, in three places, and keep the smallest reading. Then check whether the listing is a maximum, such as EGNBU's up to 90 x 210 cm, or a fixed curtain, such as YRH's 80 x 200 cm. Measuring the glass alone leaves the tape with nowhere to land.
Does fine mesh or 1 mm holes mean midge mesh?
No. Streme's guide treats 18 x 16 as standard insect mesh and 30 x 20 as genuine midge mesh, and it says 20 x 20 does not stop midges. None of these ten technical tables print either count. Flux Phenom's 1 mm holes and MOEGFY's fine mesh are the words on those pages, not a 30 x 20 specification.
Will adhesive hook-and-loop mark uPVC or fail in heat?
It can. Listings claim a no-drill tape fix on a clean, dry frame. Reviewers of the tesa sheet, the MOEGFY nets and several door curtains report the strip lifting on paint, on wood, and when the tape gets hot. tesa's residue-free line is a claim. Other reviewers in this set found glue left behind.
Can a fly screen keep a child or a cat from falling?
No. Leeds City Council describes a window restrictor as the device that limits an opening to about 10 cm. A mesh can pull away. Reviewers say a cat tore the tesa sheet, took a NeatiEase panel down, and that the MOEGFY nets are not indoor cat safety.
