Introduction
Why Bird Netting Is Essential for Vineyards
Bird damage is one of the most costly challenges in viticulture. Across the world, species such as starlings, silvereyes, robins, finches, and blackbirds can destroy 20–40% of a vineyard’s potential yield—especially during veraison, when sugar levels rise and grapes become highly attractive.
Traditional deterrents such as noise cannons, reflective tapes, or predator calls provide only temporary protection. Birds quickly adapt, and vineyards experience inconsistent results.
Bird netting, however, remains the single most effective, predictable, and economical method of crop protection, particularly for wineries where fruit quality directly influences wine style, production consistency, and profitability.
This guide explains the three main types of vineyard bird netting, how they work, and how to choose the right solution for your vineyard or winery.
Introduction
Every year, billions of dollars of grapes and other crops are lost to birds.
Large numbers of birds and other pest animal species can threaten your vineyard’s economy and ability to produce wine or generate income from tourists.
Providing effective bird control can save you money and maintain the production level of your vineyard.
Several birds eat grapes, including robins, starlings, mockingbirds, finches, and blackbirds.
One of the most popular bird control methods for vineyards is bird netting.
Bird netting comes in a wide variety of styles and can protect grapevines from birds that pose a threat to fruit production.
This article discusses three types of vineyard bird netting that can target these pests.
Vineyard Side Netting (Zone Netting)
The most popular modern netting solution for commercial vineyards.
Vineyard side netting is designed to protect only the fruiting zone, leaving the canopy open for ventilation and spray penetration. It is widely used in Australia, New Zealand, Canada, and increasingly in the eastern United States.
How It Works
Side nets are installed along both sides of the vine row and fastened above and below the fruiting zone, creating a secure envelope around the grape clusters.
Advantages
- Highly efficient installation — saves 25–30% labor compared with drape netting
- Can remain in the vineyard year-round when rolled up on wire
- Excellent airflow and spray penetration for disease management
- Minimal interference with tractors or harvest equipment
- Consistent bird exclusion when edges are properly sealed
Limitations
- Requires careful fastening at top and bottom
- Not suitable for extremely windy sites unless reinforced
Best For
- Medium to large vineyards
- Wineries needing predictable protection with low labor inputs
- Regions with repeated bird pressure during ripening
Vineyard Drape Netting (Single-Row & Multi-Row)
The traditional, full-coverage option.
Drape netting covers the entire vine canopy like a curtain and is the most familiar type of vineyard netting worldwide. It can be applied manually or with mechanical applicators.
Installation Types
- Single-row drape — covers one row at a time
- Multi-row drape — wider nets covering 2–3 rows per pass, reducing installation time
Advantages
- Comprehensive bird protection for both canopy and fruit
- Multi-purpose — may also reduce hail impact and insect entry
- Lower cost compared to overhead systems
- Flexible and suitable for all vineyard sizes
Disadvantages
- Manual draping is labor intensive without machinery
- Tendrils often catch the mesh, complicating removal
- Must be secured tight around the trunk to prevent bird entry
Best For
- Small to mid-size vineyards
- Growers who need an inexpensive, multi-season solution
- Vineyards in temperate climates with moderate bird pressure
Overhead Vineyard Netting (Canopy Netting)
Full-vineyard, permanent protection system.
Overhead netting covers the entire vineyard like a roof, suspended from poles and wires. It is common in regions with extreme climate risks.
Major Benefits
- Highest level of bird exclusion
- Protects from hail, sunburn, wind, and animal damage
- Creates a stable microclimate, improving fruit uniformity
- Long lifespan with predictable ROI
- No interference with vineyard operations; tractors can pass underneath
Drawbacks
- Highest initial installation cost
- Requires structural posts and wire infrastructure
- Best suited for long-term investment planning
Best For
- High-value wine grapes (Pinot Noir, Chardonnay, Riesling, Syrah)
- Regions with hail, intense UV, strong winds, or large flocks
- Wineries focused on consistent premium quality
Bird Netting Materials: Extruded vs Knotted vs Knitted
Different bird netting materials offer different performance characteristics.
This comparison table helps vineyard owners quickly identify which option is best suited to long-term vineyard protection.
Bird Netting Material Comparison Table
| Material Type | Manufacturing Method | Strength & Durability | Cost Level | Advantages | Limitations | Suitability for Vineyards |
|---|---|---|---|---|---|---|
| Extruded Netting | Polypropylene extruded through dies forming diamond or square mesh | ⭐ Low strength ❗ Prone to tearing | 💲 Lowest | – Very lightweight- Cheapest option | – Breaks easily under tension- Not UV-stable enough- Typically one-season use | ❌ Not recommended (too weak for vineyard use) |
| Knotted Netting | HDPE monofilament twisted into ropes and mechanically knotted | ⭐⭐⭐ Very strong Resistant to impact | 💲💲 Higher | – Extremely tough- Each mesh independent (damage doesn’t spread)- Long lifespan | – Heavy and rigid- More expensive- Over-engineered for grapevine use | △ Partially suitable (good for perimeter or wildlife fencing, not canopy use) |
| Knitted Netting (Raschel) | HDPE monofilament knitted on Raschel machines | ⭐⭐⭐⭐ High durability Excellent tensile stability UV-stabilized 5–10 years | 💲💲 Moderate | – Best balance of strength + flexibility- Lightweight & easy to install- High production output → stable cost- Industry standard for agriculture | – Must reinforce edge stitching | ✅ Best option for vineyards (global standard for bird control) |
Professional Verdict
- Extruded Netting → Good looking but not durable, Not suitable for vineyards .
- Knotted Netting → High strength but high cost, suitable for fencing, not suitable for covering fruit areas.
- Knitted Netting (Best) → Vineyard Standard Solution : Durable, lightweight, adaptable to a variety of installation methods.
Conclusion: Knitted (Raschel) Netting is the best choice for vineyard bird control.
How to Choose the Best Bird Netting for Your Vineyard (Decision Matrix)
Choosing the right bird netting depends on five key variables:
- Vineyard size (small / medium / large)
- Climate conditions (high wind, strong UV, hail, humidity)
- Bird pressure level (low / medium / high)
- Budget (low/medium / high)
- Labor availability (whether manual draping is feasible)
Bird Netting Selection Matrix (Professional Vineyard Version)
| Vineyard Scenario | Recommended Net Type | Why This Works |
|---|---|---|
| Large commercial vineyards | Side Netting | Supports mechanization; fastest deployment; lowest labor cost over large acreage |
| Small wineries / boutique vineyards | Single-row Drape Netting | Lowest upfront cost; flexible for small blocks; multi-purpose protection |
| Hail-prone or high-UV regions | Overhead Netting | Provides multi-risk protection (birds + hail + sunburn) and stable microclimate |
| High-wind regions | Side Netting + Reinforced Anchoring | Best structural stability; reduced risk of net displacement |
| Late-season migratory bird pressure | Side Netting (Fine Mesh) or Overhead | Ensures full exclusion during peak sugar accumulation |
| Low labor availability | Side Netting | Can remain on the vine year-round; minimal seasonal labor required |
| Mixed-variety vineyards with uneven ripening | Side Netting | Allows selective picking without removing nets |
Expert Insight (Why the Matrix Matters)
Most vineyards choose netting based on cost alone—but climate, bird species, and labor constraints often have a significantly greater impact on long-term results.
- Side Netting delivers the best ROI for most commercial vineyards.
- Drape Netting is still ideal for growers who want flexibility and low upfront cost.
- Overhead Netting performs best in extreme climates or premium-wine regions where consistency is worth the investment.

How to Install the Three Types of Vineyard Bird Netting
Correct installation ensures that any type of bird net performs effectively through wind, rain, and the pressure of ripening-season birds.
Below is a practical overview of how each net type is typically installed in commercial vineyards, with corresponding video demonstrations.
Installing Vineyard Drape Netting (Single-Row & Multi-Row)
Drape nets are pulled over the canopy and secured around the trunk or bottom wire to prevent birds from entering underneath. They must be applied gently to avoid tangling with shoots, and multi-row nets can be deployed faster with applicators.
🎥 Video:
Installing Vineyard Side Netting (Zone Netting)
Side nets are clipped to the top wire, wrapped around the fruiting zone, and sealed at the bottom wire to block bird access. This system installs quickly, supports mechanized tools, and can remain in place year-round when rolled onto mid-row wires.
🎥 Video:
Installing Overhead Vineyard Netting (Canopy Netting)
Overhead nets are suspended above the canopy using extended posts and perimeter wires, then tensioned to create a stable “roof” over the vineyard. They allow full equipment access underneath while providing season-long protection against birds, hail, and sunburn.

FAQs About Vineyard Bird Netting
Do bird nets affect grape ripening?
No. Properly installed nets allow full light penetration and ventilation. They prevent sunburn, shrivel, and sugar loss from heat stress, improving ripening consistency.
What mesh size is best?
For starlings and finches, 15×15 mm diamond mesh is ideal; for silvereyes and smaller birds, a finer mesh may be needed.
Can I leave nets up year-round?
Side nets can stay year-round when rolled; drape nets should be removed and stored.
Will birds try to enter from below?
Yes. This is why lower edge sealing is essential, especially with side nets.
Conclusion
Bird netting remains one of the most cost-effective and dependable tools for safeguarding grape yield and wine quality. Understanding the three main netting systems—side netting, drape netting, and overhead netting—allows vineyard owners to match the right solution to their climate, vineyard size, and bird pressure.
