Why the Right Bird Netting Matters
Buying bird netting without knowing what to look for is a common and costly mistake. Choose a mesh that's too large, and smaller birds slip right through. Choose a material that degrades in UV light, and you'll be replacing it within a season. This guide walks you through every key decision so you get it right the first time.
Step 1: Identify the Target Bird Species
The species you're dealing with determines the mesh size you need. Different birds require different opening sizes:
- Pigeons & large birds: 50mm (2-inch) mesh is the standard choice
- Starlings & medium birds: 28mm (1.1-inch) mesh will exclude them effectively
- Sparrows & small birds: 19mm (¾-inch) or smaller mesh is required
- Garden insects and very small birds: 12mm (½-inch) or fine netting works best
When in doubt, go smaller. A finer mesh excludes more species and gives you more flexibility.
Step 2: Choose the Right Material
Bird netting comes in several materials, each suited to different environments and budgets:
| Material | Durability | UV Resistance | Best For |
|---|---|---|---|
| Polypropylene (PP) | Moderate | Good (UV-stabilised) | Gardens, fruit trees, general use |
| Polyethylene (PE) | High | Excellent | Outdoor, long-term installations |
| Nylon (Knotted) | Very High | Moderate (needs treatment) | Commercial, structural applications |
| Stainless Steel Wire | Exceptional | N/A (metal) | Industrial, permanent installations |
For most residential and garden applications, UV-stabilised polyethylene offers the best balance of durability and value. For rooftop or commercial use, consider heavy-duty knotted nylon or stainless steel.
Step 3: Consider Twine Thickness (Ply)
Netting ply refers to the thickness of the individual strands. Heavier ply means greater tensile strength and resistance to tearing:
- Lightweight (thin ply): Suitable for garden beds and temporary use
- Medium ply: Ideal for fruit cages, balconies, and semi-permanent setups
- Heavy ply: Best for commercial installations, warehouses, and rooftops where birds may press against the net
Step 4: Measure Your Coverage Area Accurately
Always measure your coverage area and add at least 10–15% extra to allow for overlap, anchoring, and securing edges. Running short of netting mid-installation wastes time and creates vulnerabilities where birds can enter.
Step 5: Check for Certifications and Standards
Quality bird netting should meet relevant standards for UV stabilisation and tensile strength. Look for products that clearly state:
- UV stabilisation rating (e.g., treated for 5–10 years of UV exposure)
- Breaking strain of the netting material
- Compliance with local wildlife protection regulations (humane, non-entanglement designs)
Quick Reference: Netting Selection Checklist
- Identify the bird species causing the problem
- Select the appropriate mesh size
- Choose a UV-resistant material suited to your climate
- Match the ply weight to the severity of bird pressure
- Measure area and buy with surplus stock
- Confirm humane design and wildlife compliance
Final Thoughts
Taking a few minutes to assess your bird problem and property requirements before purchasing will save you money, effort, and frustration. The right bird netting, correctly installed, can last a decade or more and provide reliable, humane bird control throughout its life.
