Spikes vs Netting for Pigeons: Which Deterrent Actually Works?

For most domestic situations — fence tops, window ledges, wall coping and garden roofs — spikes are the more practical choice: they install in minutes, need no specialist tools, and hold up for years with zero maintenance. Netting is better suited to large enclosed areas like a courtyard or the underside of solar panels, where you need a physical barrier across an open space rather than a deterrent along a surface edge. Neither is perfect everywhere, so the right answer depends on where your pigeons are landing and what you can realistically fix to the surface.

What problem are you actually trying to solve?

Before comparing products, nail down where the pigeons are causing trouble — the answer changes everything.

Pigeons landing on a surface edge (fence top, wall, ledge, guttering, roof ridge, satellite dish) — this is a linear perching problem. Spikes are designed exactly for this. You run them along the edge and pigeons can no longer land.

Pigeons roosting inside a space (under a balcony, beneath solar panels, inside a garage roof void, in an open outbuilding) — this is an enclosure problem. Netting creates a physical barrier across the opening. Spikes on their own won't help if the birds are getting in through a gap above or behind them.

Pigeons fouling a car on the drive — this is a different problem again. Neither spikes nor netting protects a car directly; the goal is to remove the perch overhead. Identify the fence, wall or roof edge the birds sit on before messing, then address that surface.

Most garden homeowners are dealing with a surface-edge problem, which is why spikes come up first in almost every comparison.

How bird spikes work — and where they fall short

Spikes make the landing surface uncomfortable by removing the flat area a bird needs to stand on. A pigeon approaching a fence top covered in spikes will flare, hover, and then move on — it can't perch safely.

Spikes work well on:

• Fence tops and fence rails
• Wall and roof coping
• Window ledges and sills
• Guttering and fascia boards
• Satellite dishes and aerials
• Signs, beams and post tops

Where standard flat spikes fall short is on any surface that climbing animals also use. A fox, squirrel or cat that walks across a fence will simply step between single-height spikes — their paws find the gaps. This is why spike design matters: ThornGuard uses an irregular three-height layout (12 mm, 22 mm and 36 mm spines on each strip) so there is no consistent gap for a paw to find. That staggered height stops climbers as well as birds, which flat deterrent strips cannot reliably do.

Spikes also struggle on curved or very uneven surfaces, and they cannot span an open gap — for that, you need netting.

How pigeon netting works — and where it becomes impractical

Pigeon netting is a UV-stabilised mesh (typically 50 mm aperture for pigeons) that is tensioned across an area to physically exclude birds from a space. Properly installed, it is highly effective and very long-lasting.

Netting works well for:

• Covering an entire courtyard or roof terrace
• Protecting the underside of solar panel arrays (combined with wire clips)
• Enclosing a balcony that pigeons are nesting on
• Protecting a vegetable garden or fruit cage from birds of all sizes

The practical problems with netting for most homeowners:

1. Installation complexity. Tensioning netting correctly requires anchor points, tensioning wire or a frame, and often a ladder or scaffolding. A poorly tensioned net sags, collects debris, and birds find their way under the edges within weeks.
2. Cost. A quality polyethylene netting job on a medium-sized balcony or roof area, professionally installed, typically runs into several hundred pounds. Even DIY netting kits for a modest area cost significantly more than a run of spikes.
3. Appearance. Netting over a garden wall or fence top looks industrial. Spikes are low-profile and — once in place — largely invisible from ground level.
4. Maintenance. Netting traps leaves, twigs and debris. It needs checking seasonally and any tears repaired promptly, or birds exploit the gap.
5. It won't stop climbing animals. A cat or squirrel will simply chew through lightweight netting or push under an edge that isn't perfectly sealed.

Cost comparison: what does each actually cost?

For a typical 10-metre fence run:

Spikes: A ThornGuard 8 m pack covers up to 8 m fitted flat — but because the strips can be split lengthways, that same pack can cover up to 24 m of run at reduced width, or you can use the full-width strips for the top rail and split strips for the sides of posts. An 8 m pack is sold on Amazon UK. For a standard 10 m fence, one pack fitted full-width or two packs split-fit covers the run comfortably. Cost: low, one-off, no specialist labour needed.

Netting: For a 10 m fence, you would need netting wide enough to drape over the top and be anchored on each side, plus fixings and tensioning wire. DIY materials alone are typically three to five times the cost of a spike solution for the same linear run — and that assumes the fence structure will support anchor points.

For enclosed spaces (solar panels, balconies), netting is often the only option that works, so cost comparison is less relevant — it becomes the right tool for the right job.

What about a combination approach?

In some situations, both work together. A common example: fitting spikes along the top coping of a garden wall to stop pigeons landing on the edge, while netting the gap under a balcony above where they were previously roosting. The spikes handle the perching problem; the netting handles the enclosure problem. Trying to net a wall top is over-engineering a simple problem; trying to spike a 3-metre courtyard opening is under-engineering a complex one.

Which should you choose?

| Situation | Best option | |---|---| | Pigeons on fence top or wall | Spikes | | Pigeons on window ledge | Spikes | | Pigeons on roof ridge or guttering | Spikes | | Cats or squirrels on fence (plus birds) | Irregular-height spikes (not flat) | | Pigeons roosting under solar panels | Netting (purpose-made solar skirt) | | Pigeons nesting on balcony | Netting | | Pigeons in open outbuilding | Netting | | Vegetable garden protection from birds | Netting or fruit cage |

For the vast majority of garden homeowners — pigeons fouling fences, walls, ledges and garden roofs — spikes are the faster, cheaper and lower-maintenance answer. If you also have squirrels or cats using the same routes, make sure you choose spikes with staggered heights rather than standard flat strips, which climbing animals simply walk straight over.

Common questions

Do bird spikes actually work on pigeons?

Yes — spikes work by removing the flat landing area pigeons need to perch. A pigeon approaching a spike-covered surface will turn away rather than attempt to land. They are most effective on defined edges (fence tops, ledges, guttering) where the pigeon's options are limited; wide flat roofs with many alternative spots take more comprehensive coverage to see a strong result.

Are bird spikes humane?

Yes. Deterrent spikes are considered a humane method under UK guidance. The spines are designed to make a surface uncomfortable to land on — they do not trap, injure or kill birds. The bird simply chooses a different place to perch. This is the same principle recommended by animal welfare organisations when advising on pigeon management.

Are bird spikes legal in the UK?

Yes, fitting deterrent spikes to your own property is legal. The one important rule: never fit spikes to, or disturb, an active bird nest — this is protected under the Wildlife and Countryside Act 1981. Check any surface before installing, and if birds are already nesting, wait until the nest is naturally vacated before fitting deterrents.
