How to Combine Netting and Exclosures for Bird Control

Birds can be both a delight and a nuisance to gardeners, farmers, and property owners. While they contribute positively to ecosystems by controlling pests and pollinating plants, certain bird species can cause significant damage to crops, fruits, ornamental plants, and even property. Effectively managing bird populations without causing harm is a challenge that requires thoughtful strategies. Two of the most effective non-lethal methods are the use of netting and exclosures. When combined strategically, these tools offer comprehensive bird control solutions that protect valuable resources while preserving bird welfare.

In this article, we will explore how to combine netting and exclosures for bird control. We will discuss their individual benefits, limitations, and how integrating them creates an efficient bird management system suitable for various settings.

Understanding Bird Problems in Agriculture and Gardens

Birds such as sparrows, starlings, pigeons, crows, and grackles often target fruit orchards, vegetable gardens, vineyards, and grain fields. They peck at fruits like cherries, blueberries, grapes, apples, and corn kernels. This can lead to:

• Reduced crop yields
• Loss of marketable produce due to damage
• Increased risk of disease transmission from damaged fruits
• Contamination of produce with droppings

In urban areas or residential gardens, birds may also cause structural damage by nesting in unwanted locations or creating noise disturbances.

Given these challenges, bird control must be humane and effective while minimizing environmental impact.

What Are Netting and Exclosures?

Netting

Netting refers to lightweight mesh fabrics designed to physically prevent birds from accessing crops or areas where they would cause damage. It acts as a barrier that birds cannot penetrate or bypass.

Types of Netting:
– Polyethylene or polypropylene netting: Durable and UV-resistant; common for agricultural use.
– Nylon mesh: Lightweight but less durable; used in garden settings.
– Metal or wire mesh: Heavy-duty but may be impractical for large areas.

Exclosures

Exclosures are physical barriers constructed around specific plants or areas to exclude birds and other animals. Unlike netting that covers large areas or entire crops, exclosures protect individual plants or smaller plots.

Common exclosure types:
– Wire cages: Made of hardware cloth or wire mesh around single trees or bushes.
– Frame structures: Wooden or PVC frames covered with mesh.
– Cloche covers: Small protective covers over seedlings or delicate plants.

Advantages of Netting and Exclosures Individually

Benefits of Netting

• Large area coverage: Suitable for entire orchards or fields.
• Durable protection: Can last multiple seasons if maintained properly.
• Versatility: Can be draped over trees, bushes, trellises, or supported by poles.
• Non-lethal: Birds are physically blocked without harm.

Limitations of Netting

• Installation complexity: Requires careful setup to avoid gaps.
• Potential damage to plants: Improper installation can cause plant stress.
• Expense: Can be costly depending on material quality and area size.
• Maintenance: Needs regular checks for tears or sagging.

Benefits of Exclosures

• Targeted protection: Ideal for high-value plants or young seedlings.
• Reusable materials: Frames can be assembled/disassembled seasonally.
• Simple design: Easy DIY solutions with common materials.
• Physical barrier: Keeps out other pests like rabbits or deer in some cases.

Limitations of Exclosures

• Limited coverage area: Not practical for large crops.
• Labor intensive: Requires building multiple units for many plants.
• Space constraints: May impede plant growth if too small.

Why Combine Netting and Exclosures?

Using netting alone over an entire orchard can be expensive and laborious. Conversely, exclosures alone may protect only a handful of plants but leave the rest vulnerable.

Combining the two methods leverages the strengths of each while mitigating their weaknesses:

1. Cost-effectiveness
2. Deploy netting on larger areas where feasible.

3. Use exclosures selectively on particularly vulnerable or valuable plants within those areas.

4. Improved efficacy

5. Netting covers broad regions preventing most bird access.

6. Exclosures provide added protection at points where birds might breach netting (e.g., ground level).

7. Flexibility

8. Adapt solutions based on plant type, location, growth stage, and budget constraints.

9. Reduced maintenance

10. Well-secured netting reduces bird pressure overall; fewer exclosures needed.
11. Exclosures prevent damage during early stages when plants are most susceptible.

Step-by-Step Guide: Combining Netting and Exclosures for Bird Control

Step 1: Assess Your Site and Identify Problem Areas

Begin by surveying your garden or farm:

• Identify which crops or plants suffer the most bird damage.
• Observe bird behavior patterns, feeding times, entry points, roosting spots.
• Note surrounding structures that birds use as perches.

This assessment helps prioritize where netting should be placed extensively versus where exclosures are necessary.

Step 2: Choose Appropriate Netting Material and Size

Select netting based on:

• Mesh size: Small enough to exclude target birds (usually 1/2 inch to 1 inch openings).
• Material durability: UV-resistant polyethylene is preferred for outdoor exposure.
• Weight: Lightweight netting is easier to install but less durable.

Order enough netting to cover the identified large areas with some allowance for securing edges firmly.

Step 3: Install Netting Properly

Key installation tips:

• Support netting using poles or trellises so it does not rest directly on plants; this prevents physical damage.
• Secure edges tightly to the ground using stakes or burying edges under soil to prevent birds from slipping underneath.
• Ensure there are no holes or gaps; join multiple pieces with clips rather than knots which can create openings.

Netting should form a complete cage over the crop zone while allowing adequate sunlight and airflow.

Step 4: Construct Exclosures for Vulnerable Plants

For individual fruits trees, berry bushes, seedlings:

• Build wire cages around trunks or stems using hardware cloth with 1/2 inch mesh openings.
• Use wooden or PVC frames covered with fine mesh fabric if wire is unavailable.
• Ensure exclosures have enough height and width to accommodate plant growth without contact.

Place these inside the larger netted area if possible for double protection.

Step 5: Monitor Regularly and Repair Damages

Check both netting and exclosures frequently during the growing season:

• Patch any holes immediately.
• Adjust tension on netting if sagging occurs.
• Remove debris trapped on nets that could weigh them down.

Monitoring ensures continued effectiveness and prevents birds from exploiting weaknesses.

Additional Tips for Effective Bird Control

Use Visual Deterrents Alongside Physical Barriers

Scare devices such as reflective tape, predator decoys (owls), or sound deterrents can complement netting/exclosure systems by discouraging birds from approaching initially.

Avoid Attracting Birds Near Protected Areas

Remove fallen fruit promptly as it attracts birds. Clean up spilled feed or seeds in nearby areas. Plant sacrificial crops away from main plantings if possible.

Consider Timing When Installing Controls

Apply netting before fruit ripens so birds do not become habituated to feeding there. Early installation prevents established feeding habits that are harder to break later.

Combine with Other Non-Lethal Methods When Necessary

If bird pressure is extreme, combining physical barriers with habitat modification, like pruning nearby perches, or altering water sources may improve results sustainably.

Conclusion

Effective bird control requires thoughtful integration of multiple strategies tailored to specific environments. Combining the broad coverage of netting with targeted protection offered by exclosures provides a versatile solution that protects crops thoroughly while remaining humane and environmentally sound.

By assessing your property’s unique needs, selecting quality materials, installing carefully, and maintaining regularly, you can significantly reduce bird damage. This integrated approach not only safeguards your valuable produce but also helps maintain balanced ecosystems by discouraging harmful feeding behaviors rather than resorting to lethal means.

Investing time in designing a combined netting-exclosure system ultimately pays off with healthier plants, higher yields, reduced losses, and satisfied stakeholders, from growers to wildlife enthusiasts alike.
