How to Install a Magnetic Fly Screen
Installing a magnetic fly screen takes about 15-30 minutes and requires no drilling or special tools. The self-adhesive strips attach to your door frame, and the screen hangs from the top strip with magnets running down the centre that automatically close behind you.

What You'll Need for Installation
Before starting, gather these basic items:
- Your magnetic fly screen kit (includes screen, adhesive strips, and pins or thumbtacks)
- Scissors or craft knife
- Measuring tape
- Cleaning cloth and methylated spirits or rubbing alcohol
- Step ladder (for high door frames)
Most magnetic fly screens come as complete kits with everything needed. Check your package includes the mesh screen, magnetic strips down the centre, adhesive mounting strips for all four sides, and securing pins or tacks as backup fasteners.
Choosing the Right Size
Measure your door frame's height and width before purchasing. Standard Australian door frames are typically 2040mm x 820mm, but sizes vary. Buy a screen slightly larger than your frame—you can trim excess material, but you can't add length.
Preparing Your Door Frame
Proper preparation ensures your magnetic fly screen stays secure through summer and beyond.
Clean the Surface Thoroughly
Wipe down the entire door frame with methylated spirits or rubbing alcohol. Remove dust, cobwebs, grease, and any residue from previous installations. The adhesive strips bond best to clean, dry surfaces. Let the frame dry completely—wait at least 10 minutes after cleaning.
Check for Damage
Inspect your door frame for peeling paint, cracks, or rough surfaces. Sand down any rough spots and consider touching up damaged paint. Adhesive strips struggle to stick to flaking or uneven surfaces.
Measure Twice
Confirm your door frame measurements and compare them to your screen dimensions. Mark the centre point at the top of your frame with a light pencil mark—this helps align the magnetic centre seam properly.
Installing the Magnetic Fly Screen
Follow these steps for a secure, wrinkle-free installation.
Step 1: Attach the Top Strip First
Peel back about 10cm of the backing from one end of the top adhesive strip. Position it along the top of your door frame, ensuring the magnetic screen seam aligns with your centre mark. Press firmly, then gradually peel and press the rest of the strip across the top, smoothing as you go to avoid air bubbles.
Step 2: Hang the Screen
Attach the screen to the top adhesive strip using the Velcro or hook-and-loop fasteners. Let the screen hang naturally to check the length and position. The magnetic seam should run straight down the centre of your doorway.
Step 3: Secure the Sides
Starting from the top and working downward, peel and press the side adhesive strips onto your door frame. Keep the screen taut but not stretched—it should hang straight without sagging or pulling. Press firmly along the entire length of each side strip.
Step 4: Attach the Bottom Strip
Trim any excess screen length if needed, leaving about 2-3cm to tuck under. Attach the bottom adhesive strip, ensuring the screen sits flush with the ground or has a slight overlap to prevent gaps.
Step 5: Add Securing Pins
For extra security, especially in high-traffic areas or homes with pets, push the included pins or thumbtacks through the screen into the door frame at regular intervals (every 20-30cm). Focus on corners and the top section where stress is greatest.
Testing and Adjusting Your Screen
Walk through your new magnetic fly screen several times. The magnets should connect smoothly from top to bottom, closing automatically behind you. If gaps appear, check these common issues:
Misaligned magnets: Adjust the screen position slightly by repositioning the top strip before it fully sets (you have about 24 hours before adhesive reaches maximum strength).
Weak closure: Ensure the magnetic strips are properly aligned and touching along their full length. Some screens have weighted bottom bars that help the magnets connect better.
Gaps at the bottom: Trim the screen to the correct length or adjust the bottom strip position. A small overlap with the floor is better than a gap.
Maintenance and Care Tips
Keep your magnetic fly screen functioning well with minimal upkeep.
Regular Cleaning
Vacuum the screen gently with a brush attachment every few weeks to remove dust and debris. For deeper cleaning, wipe with a damp cloth and mild detergent. Never use harsh chemicals that might damage the mesh or magnetic strips.
Seasonal Checks
Before peak fly season, inspect the adhesive strips and replace any that have loosened. Check the magnetic strips for damage and ensure they still align properly. Most quality screens last 2-3 seasons with proper care.
Pet Training
If you have dogs or cats, teach them to push through the screen gently. The magnets are strong enough to stay closed against light breezes but will open easily with gentle pressure. Avoid letting pets scratch or claw at the mesh.
Frequently Asked Questions
How long does a magnetic fly screen last?
Quality magnetic fly screens typically last 2-3 years with regular use. Lifespan depends on traffic levels, weather exposure, and maintenance. Screens in protected doorways last longer than those facing direct sun or harsh weather.
Can I install a magnetic fly screen on a sliding door?
Yes, magnetic fly screens work on sliding doors. Measure the opening carefully and ensure the screen is wide enough to cover the entire opening when the door is fully open. Some kits are specifically designed for wider openings.
Will the magnets work if I have a security door?
Magnetic fly screens install on the door frame itself, so they work alongside security doors. Install the screen on the outer frame so the security door can still close properly inside it.
Do magnetic fly screens keep out mosquitoes?
Yes, if the mesh is fine enough. Look for screens with a mesh size of 1.2mm or smaller to block mosquitoes effectively. Standard fly screen mesh (around 1.5-2mm) stops flies but may let smaller insects through.
Can I remove and reinstall a magnetic fly screen?
You can remove the screen, but the adhesive strips typically won't restick effectively. Plan to purchase new adhesive strips if you need to relocate or reinstall your screen. The mesh and magnetic components are reusable.
