Why pigeons come back, and how full-opening nets stop the cycle
If birds can still land on a ledge or AC line, they will. Coverage of the whole opening is the difference between a temporary scare and a lasting fix.

Partial deterrents train birds to wait
Spikes on one ledge while the neighbouring AC tray stays open is a common reason pigeons 'come back after treatment'. Birds simply shift a few feet. The same happens when a net covers only the front rail and leaves the side return or top gap open.
A durable bird-control job maps every landing surface in the bay: rail, slab edge, AC outdoor unit, duct mouth and any decorative ledge. Then the net or spikes are planned as one system rather than as separate gadgets.
Choosing mesh that keeps light and airflow
Most residential balconies do well with UV-stabilised HDPE mesh tensioned evenly across the full opening. The mesh should be fine enough to deny footholds without turning the balcony into a dark box. Frame colour and border rope finish matter for how visible the install looks from inside.
On ducts and shafts the priority shifts to access for cleaning and service. Removable panels or zipper openings are planned where technicians still need to reach equipment, otherwise the net gets cut open later and the gap stays.
- Cover the full opening, including side returns and top gaps
- Treat AC trays and duct mouths as part of the same job
- Use UV-stable mesh with even tension, not a sagging temporary panel
- Plan service access where equipment still needs maintenance
Aftercare that keeps the net working
Clear droppings and nesting material before they cake into the mesh. A light wash during dry months keeps UV coatings cleaner and makes tension checks easier. If one panel loosens, re-tension early — a soft panel becomes a landing pad again.
If you already tried spikes alone and birds returned, send a photo of the full bay including side walls. That is usually enough for us to say whether a full net, a hybrid, or a ledge redesign is the right next step.
Related questions
Will pigeons find a way back in after netting?
Only if the enclosure was left with a gap, which in practice means a corner or a service penetration that was not properly closed. A correctly fitted net denies access outright. That is why we clear existing nesting material first and check corners and pipe penetrations last, since those are where birds actually get through.
Can one net keep birds out and also stop a fall?
No, and treating them as interchangeable is the most common mistake we are called to correct. A light bird-exclusion mesh will not arrest a person or a heavy object. Where there is a genuine fall risk we specify a rated net with rated anchorage, which is a different product at a different price.
If you net our duct, how do we service the pipes later?
Access has to be designed in from the start, which is why we form laced access panels at agreed positions and record where they are for the facilities team. A net with no access provision gets cut open the first time the riser needs work and is never repaired, which defeats the whole installation.
