Fly screen care and repair: the complete guide

Looking after a fly screen (also called an insect screen) comes down to three habits: a quick vacuum with the brush attachment to lift the dust, a wash in lukewarm water with a mild soap once or twice a season, and replacing the wear parts (adhesive strips, magnetic strip, hook-and-loop tape) as soon as they start to give up. Never a pressure washer, never solvents. A small tear can be rescued with a patch, but beyond that it is better to replace the part concerned than to battle on. Here is the complete guide, from the spring clean to winter storage.

A fly screen works hard all summer: pollen, dust, cat paws, children's fingers, thunderstorms. The good news is that looking after it takes very little effort, as long as you do the right things at the right moment. And if yours is already showing signs of fatigue, no panic: we will also look at what can genuinely be repaired, what is better replaced, and how to give it a second life without buying everything again.

Routine cleaning through an Australian summer

Dust and pollen settle into the weave, gradually grey the mesh, slow the airflow and dull the view. Regular care keeps a fly screen almost invisible, pleasant to look through and fully effective.

How often?

At the height of the season, a simple monthly dusting is plenty. Save the full clean for two key moments: in spring, before you put the screen back up, and in autumn, before you store it away. If you live in town, near a busy road, or in the countryside during mowing and harvest, bring those sessions a little closer together: the mesh will thank you for it.

The gentle method, in three steps

Always start dry. Run the vacuum over the screen with the brush attachment on a moderate setting, working from top to bottom and, if you can, on both sides of the mesh. That one action lifts dust, pollen and cobwebs without disturbing the weave. Work gently into the corners and along the bottom of the panel, where everything collects.

For the full clean, fill a bowl with lukewarm water and a little mild soap: washing-up liquid or a plain household soap, nothing stronger. Dip a soft sponge, wring it out well, then work across the mesh in small sections without pressing, supporting the fabric with your other hand if it is loose. Finish with a clear-water rinse to remove every trace of soap, which would otherwise attract dust.

Then let it dry completely in the open air, laid flat or hung up, ideally in the shade. Fibreglass mesh (a tight 18×16 threads-per-inch weave on our models, all the details are in the technical specifications) copes very well with water: it is rough handling it dislikes.

What you should never do

Never a pressure washer: the jet distorts the weave and can punch straight through the mesh in a second. Never solvents, bleach or scouring powders, which attack the fibre and the adhesives alike. And never a squirt of insecticide "to boost the protection": it does nothing on a fly screen, whose barrier is purely physical, and it harms the mesh as much as the air in your home.

Magnetic strip, hook-and-loop tape and frame: the parts people forget

This is the part everyone forgets, and yet it is often where a removable fly screen wins or loses its grip. A closure that no longer catches properly feels like a worn-out product, when in most cases a simple clean settles the question.

The magnetic strip

Over time, dust and tiny debris slip in along the magnets and weaken their hold. Run a dry cloth, or a barely damp one, along the full length of the strip on both sides. While you are there, check the alignment: magnets that face each other properly snap shut on their own, in a single movement, just like on day one.

The hook-and-loop tape

Velcro loves pet hair, textile fluff and stray curtain threads. If you have a cat or a dog, you already know exactly what we mean. Pull the hairs out by hand or with tweezers, then finish with the vacuum. Clean hook-and-loop tape recovers almost all of its original grip.

The window or door surround

Spare a thought for the surface the adhesive strip is stuck to. A clean, dry frame, wiped with a lightly soapy cloth and then dried properly, is what keeps the adhesive firmly bonded to its support. It is a small detail, but it is the one that prevents things peeling off in the middle of August.

Patching a torn screen: when it holds and when it does not

When a repair is worth it

The ideal candidate: a small, clean hole no bigger than a coin, in the middle of the mesh, well away from the edges, the seams and the magnetic strip. In that case, a roll of clear fly screen repair tape from any hardware shop does the job nicely. Cut a piece slightly larger than the hole, lay it perfectly flat, ideally on both sides of the mesh, and smooth it down firmly. On a clean, fine snag, a few stitches of polyester thread can also close the mesh neatly, as long as you pull the stitches tight enough to leave no way through.

The honest limits

A patch is a plaster. It shows, it holds up only so well over time on a taut panel that moves every time the screen is opened, and it never gives the affected area back its original strength. As soon as the tear reaches an edge, a seam or the magnet zone, or the fabric is stretched out of shape around the hole, the repair will not hold: every use will pull on it until it gives way. At that point, repairing the fly screen is no longer the right question; the right question is which part to replace.

Spare parts: replacing the piece that wore out

Here is the real secret to a long life: on a well-designed fly screen, the mesh is almost never the first thing to go. It is the consumables. The adhesive strip tires after a few summers of sunshine, the hook-and-loop tape clogs up, the backing holding the magnets eventually lifts. Throwing out a whole fly screen because an adhesive strip has reached the end of its life is a bit like changing your car because the wiper blades are worn.

That is exactly why those parts exist separately in our shop: a replacement hook-and-loop adhesive strip for doors, a replacement magnetic adhesive strip for windows, and more broadly a whole spare parts collection. Replacing a strip costs a fraction of the price of a new screen, takes no tools, and it is precisely what lets a well-cared-for magnetic window fly screen last 8 to 20 years depending on care.

And if you are weighing up whether to patch up an old framed model or move to a removable system, our custom magnetic fly screen buyer's guide lays out the debate calmly, option by option.

Taking the screen down for the off-season

With the mosquitoes gone, your fly screen has earned its break. Taking it down is not compulsory, but it is the single thing that extends its life the most: less UV, less frost, less wind. A few months under cover each year and both the mesh and the adhesives age noticeably more slowly.

Taking it down

Good news with magnetic models: fitted without drilling, they come off as easily as they went up, with no tools. Peel the panel away gently, starting from one corner, without yanking at the strip. Use the moment to give it the autumn clean described above: the screen will be clean and ready to go back up in spring.

Storage

Once the panel is perfectly dry, store it flat, under a bed or on top of a wardrobe, or rolled loosely around a cardboard tube. The one absolute rule: never fold the mesh. A crease marks fibreglass permanently and creates a weak point that will resurface the first time the panel is put under tension. Choose somewhere dry, out of the sun, and out of reach of the cat, who would find that roll very much to their liking.

In spring, putting it back up takes only a few minutes; if you need a reminder of the steps, the installation guide goes through them one by one.

Habits that shorten the life of a screen

To finish, the summary worth keeping in mind: most damaged fly screens do not die of old age, but of one action too many.

The mistake	The risk	The right reflex
Pressure washer	Mesh distorted or punctured	Soft sponge and lukewarm soapy water
Bleach, solvents, insecticide sprays	Weakened fibre, damaged adhesives	Mild soap only
Folding the mesh to store it	Permanent creases, weak points	Store flat or loosely rolled
Scrubbing hard at an ingrained mark	Weave stretched in that spot	Let the soapy water work, light strokes
Putting the panel away still damp	Mould and musty smells by spring	Dry fully in the open air before storage
