Bird Netting vs Bird Spikes: Which Is Right for Your Property?
Bird netting and bird spikes are the two most common professional bird deterrent methods in the UK. Both are humane, legal, and effective — but they solve different problems. Choosing the wrong one wastes money. Choosing the right one solves your bird problem permanently.
This guide compares bird netting and bird spikes across every factor that matters: effectiveness, cost, lifespan, appearance, maintenance, and application — so you can make an informed decision before investing.
What Is Bird Netting?
Bird netting creates a physical barrier that completely excludes birds from a defined area. The net is stretched across an opening, under a canopy, across a rooftop, or around a building recess and secured with tensioned wire rope.
How it works: The net prevents all bird access. Birds cannot land, roost, or nest within the netted area. It is the most comprehensive bird exclusion method available.
Best for: Large areas, complete exclusion, loading bays, warehouse interiors, courtyards, undercrofts, and any space where you need zero bird access.
What Are Bird Spikes?
Bird spikes are rows of blunted metal or polycarbonate pins that create an uneven surface on ledges, signs, parapets, and other flat surfaces. Birds cannot land on a spiked surface because there is no stable grip point.
How it works: Spikes make it physically impossible for birds to land on the treated surface. The bird moves on to an alternative location.
Best for: Narrow surfaces, ledges, window sills, sign tops, fascia boards, parapets, gutters, and any surface where birds land and roost.
Head-to-Head Comparison
| Factor | Bird Netting | Bird Spikes |
|---|---|---|
| Coverage | Total area exclusion | Surface-level only |
| Effectiveness | 100% when correctly installed | 100% on treated surfaces; birds may relocate to untreated areas |
| Best species | All species (mesh size determines which) | Pigeons, starlings (standard). Gulls require wide-profile spikes. |
| Lifespan | 10-15 years (UV-stabilised HDPE) | 15-20 years (stainless steel); 5-10 years (polycarbonate) |
| Guarantee | 10-year guarantee | Varies by product |
| Visibility | More visible on open facades | Virtually invisible from ground level |
| Maintenance | Annual inspection recommended | None required |
| Cost | Higher (material + installation + tensioning) | Lower per linear metre |
| Heritage suitability | Yes, with conservation fixings | Yes; wire systems preferred for visible areas |
| DIY feasible? | No — requires specialist equipment | Possible, but professional installation delivers complete coverage |
When to Choose Netting
- You need zero bird access to an area (food manufacturing, loading bays, internal spaces)
- The area is large and open (warehouse roof voids, undercrofts, covered walkways)
- You need to meet compliance requirements (BRC, SALSA, environmental health)
- Birds are entering inside your building, not just landing on external surfaces
- You are protecting a courtyard, balcony, or enclosed outdoor space
When to Choose Spikes
- Birds are landing on narrow external surfaces (ledges, sills, signs, parapets)
- You need a cost-effective solution for a defined perimeter
- Visual discretion is important — spikes are less visible than netting
- You want a maintenance-free solution
- The property is residential with roosting on roof ridges or window sills
When to Use Both
Many properties require a combination. A typical commercial installation might include:
- Netting across the loading bay opening to prevent bird entry
- Spikes along the parapet above the building entrance
- Wire systems on the facade detail where spikes would be unsightly
The best solution depends on your property, the species, and where the birds are causing problems. This is exactly what we assess during a free survey.
What About Wire Systems?
Post-and-wire deterrent systems are a third option — spring-loaded posts with tensioned wire that creates an unstable landing surface. Wire systems are preferred for heritage buildings and visible facades where spikes would be visually intrusive.
Wire systems are effective against pigeons and starlings but may not deter larger gulls.
What About Solar Panels?
Neither netting nor spikes are the right solution for solar panels. Solar panel bird proofing uses galvanised steel mesh guards secured with non-penetrative clips — a method specifically designed for solar panel frames. From £250.
Key Takeaways
- Bird netting provides total area exclusion — 100% effective when correctly installed
- Bird spikes prevent landing on treated surfaces but birds may relocate to untreated areas nearby
- Choose netting for large spaces, internal areas, loading bays, and compliance-critical environments
- Choose spikes for narrow ledges, parapets, signs, and residential properties where discretion matters
- Many commercial properties need both — netting for openings, spikes for external ledges
- Neither netting nor spikes are right for solar panels — use dedicated mesh guards instead
- Wire systems are the preferred option for heritage buildings and architecturally sensitive facades
- A free survey is the best way to determine which method suits your specific property
