# Is Garden Netting Safe for Birds and Hedgehogs?

Whether garden netting is safe for birds and hedgehogs depends almost entirely on what type you use and how you install it. The wrong mesh left loose overnight is enough to trap a hedgehog by its leg, or snare a fledgling bird before it can fly its way free.

 

As of 2026, garden netting remains one of the leading causes of hedgehog admissions to UK wildlife hospitals, based on rescue data from centres including St Tiggywinkles Wildlife Hospital. The risk is real, but it's largely preventable once you know what makes one net dangerous and another safe.

 

## The Short Answer: It Depends Entirely on How You Use It

 

Garden netting is not automatically safe for birds and hedgehogs. Plastic mesh larger than 6mm is the main entrapment risk. Hedgehog legs and snouts catch in open, loose mesh during night-time foraging.

 

Fledgling birds walk into unsecured ground-level netting and cannot pull free. Choose fine mesh of 6mm or below, keep it taut, and lift it at dusk, and the risk drops to near zero.

 

## Why Garden Netting Sends Thousands of Animals to Wildlife Hospitals Every Year

 

Wildlife rescue centres across the UK treat hundreds of birds and hedgehogs for netting injuries each year. The [British Hedgehog Preservation Society](https://www.britishhedgehogs.org.uk) lists garden netting as one of the most consistent hazards hedgehogs face, alongside roads and garden strimmers. Many animals arrive after struggling for hours, which tightens the mesh and causes deeper cuts, fractures, or loss of circulation.

 

The problem peaks where two vulnerable seasons overlap. Hedgehogs forage actively between April and October, setting out at dusk through lawns, flower beds, and under fruit cages. Fledgling birds are on the ground between May and August, not yet capable of sustained flight, putting them directly in contact with low or ground-level netting.

 

What makes it worse is the panic response. When a hedgehog or bird gets a leg, spine, or beak caught, it thrashes. That struggling tightens the mesh further, cutting off circulation and causing tissue damage within minutes.

 

By morning, the injury is often too severe to survive.

 

Slow worms, grass snakes, frogs, and bats all feature in netting casualty reports too. In the UK, wild birds and their young are protected under the Wildlife and Countryside Act 1981, and knowingly leaving an animal trapped is covered by the Animal Welfare Act 2006. Most incidents are accidental, but the law makes clear that wildlife welfare in your garden is a genuine responsibility.

 

## The Netting Types That Cause the Most Harm: Why Mesh Size Is Everything

 

Not all garden netting carries the same risk. The single biggest factor is mesh size. Open mesh gives a hedgehog's leg or a bird's foot somewhere to push through but not pull back out, especially once the animal panics.

 

| Netting Type | Typical Mesh Size | Wildlife Risk Level |
| --- | --- | --- |
| Loose plastic fruit netting | 20mm to 50mm | High |
| Knotted nylon netting | 20mm to 40mm | High (knots tighten under struggle) |
| Fine insect mesh | 1mm to 3mm | Very low |
| Welded steel or galvanised mesh | 6mm | Low |
| Wildlife-friendly polypropylene | 6mm or below | Low (when correctly installed) |

 

Knotted netting is particularly hazardous. As an animal struggles, the knot structure tightens rather than flexes, making escape nearly impossible without human help.

 

Material matters too. Thin polythene netting, the semi-transparent type sold on rolls at garden centres, is the most commonly involved in wildlife casualties. It's nearly invisible to birds, sags under its own weight, and its mesh is typically 20mm or larger.

 

Pond netting is a separate risk worth flagging. Netting stretched over a garden pond to deter herons should sit at least 30cm above the water surface. Net laid flat on or near water level can trap frogs, hedgehogs coming to drink, and waterfowl.

 

Some gardeners confuse soft [natural plant support twine](https://gardenerexpert.com/hemp-garden-twine-for-plants/) with garden netting. They're not the same hazard. Open-grid plastic mesh is the problem.

 

Single strands of twine used to train plants don't create the grid-like pockets that trap wildlife.

 

The [RSPB](https://www.rspb.org.uk) recommends a maximum mesh size of 6mm in areas where birds and small mammals are active. If your current netting doesn't meet that standard, replacing it with fine insect mesh is the fastest fix.

## How to Use Garden Netting Without Putting Wildlife at Risk

 

The netting itself is only part of the problem. How you install and manage it matters just as much. Follow these three practices and you remove most of the wildlife risk from any netting setup.

 

### Secure every edge to the ground

 

A loose perimeter is the number one cause of hedgehog entanglement. If there's any gap between the netting and the soil, a hedgehog will push through it and get its spines caught on the way back out.

 

Use tent pegs or soil staples along every edge, spaced no more than 20cm apart. For fruit cages, check that no section sags inward or creates a pocket at ground level. A length of [strong natural cordage](https://gardenerexpert.com/strong-natural-garden-twine/) threaded along the base can press down loose sections before you get the stakes fully in.

 

### Remove or lift netting at dusk

 

Hedgehogs begin moving at twilight. If your netting is flat on the ground at dusk, it's directly in the path of peak foraging time.

 

Lift the netting edges off the ground each evening and replace them at dawn. For strawberry beds, prop the sides up with short canes. It takes a couple of minutes and removes almost all overnight entanglement risk.

 

### Check nets every morning

 

Walk your netting at the start of each day. Look for any animal caught overnight, any tears that have widened the mesh, and any section that has sagged loose from its stakes. Finding an animal early is what makes the difference between a live rescue and a fatality.

 

## Safer Alternatives That Protect Your Crops Without the Risk

 

If the daily check and dusk routine is difficult to maintain consistently, these alternatives offer similar crop protection with far less wildlife risk.

 

**Rigid fruit cages** are the safest option for soft fruit. A walk-in structure with solid framing and fine metal mesh removes entanglement risk entirely. The upfront cost is higher, but daily management drops to almost nothing.

 

**Horticultural fleece** works well for brassicas and newly seeded patches. It lays flat without creating the open grid structure that traps wildlife. The trade-off is reduced light and airflow, making it less suited to fruiting crops that need pollinators.

 

**Fine insect mesh** (1mm to 3mm aperture) protects against pests and birds without any entanglement hazard. The mesh is too fine for any leg or body part to enter, so the entrapment problem doesn't arise.

 

**Visual deterrents** like reflective tape or raptor decoys can deter some bird species in open areas, but they don't protect against ground-feeding birds and offer nothing for hedgehogs.

 

For climbing plants, a cane framework with [biodegradable plant ties](https://gardenerexpert.com/jute-garden-twine-for-plants/) replaces netting for beans, peas, and cucumbers entirely. For broader vegetable training, [natural twine paired with a cane support](https://gardenerexpert.com/natural-garden-twine-for-vegetables/) handles most growing needs without any mesh involved.

 

## What to Do If You Find a Bird or Hedgehog Trapped in Netting

Finding a trapped animal is stressful, and the instinct is to pull it free fast. Don't. Pulling against tightened mesh tears skin, breaks limbs, and drives netting deeper into spines or feathers.

 

Stop, stay calm, and assess before you touch anything.

 

The right tool is a pair of blunt-tipped scissors or nail scissors. Cut the netting away from the animal rather than pulling the animal out of it. Work one strand at a time and support the animal's body weight with your free hand throughout.

 

Once the animal is free, check for visible injuries. If there's nothing obvious, place it in a quiet shaded spot and watch for 20 to 30 minutes. A hedgehog walking away steadily or a bird that takes flight is a good sign.

 

Any animal that stays put, bleeds, has a dangling limb, or shows laboured breathing needs professional help right away.

 

Contact your nearest wildlife rescue centre or call the RSPCA on 0300 1234 999 (England and Wales). The British Wildlife Rehabilitation Council can direct you to a local specialist. Don't apply antiseptic, offer food or water, or attempt to splint a limb before speaking to a professional.

 

Keeping the animal quiet and contained is the best thing you can do until expert help arrives.

## FAQs: Garden Netting and Wildlife Safety

 

### What mesh size is safe for hedgehogs and birds?

 

The recommended maximum is 6mm. Any mesh larger than that creates a potential leg or snout trap for hedgehogs, and a foot or wing trap for birds. Fine insect mesh at 1mm to 3mm is the safest option for ground-level use near known wildlife corridors.

 

### Can I leave garden netting on overnight?

 

Not unless every edge is firmly staked and the mesh is 6mm or finer. Hedgehogs are most active between dusk and dawn. Unsecured or large-mesh netting left out overnight is when most entrapments happen, and an animal caught late at night won't be found until morning.

 

### Is cheap plastic fruit netting the most dangerous type?

 

Yes. Loose polythene fruit netting with 20mm-plus mesh is behind the majority of wildlife casualties. It's nearly invisible to birds, sags easily, and its mesh is large enough to trap a hedgehog's leg or a bird's foot with no way back out.

 

### When is the highest-risk season for garden netting?

 

The peak risk window runs from May through August. Fledgling birds are on the ground during this period and hedgehog foraging activity is at its most intense. If you're using any open-mesh netting during these months, a daily morning check is non-negotiable.

 

### Are there plant-friendly alternatives that carry no wildlife risk?

 

Yes. Fine insect mesh, horticultural fleece, and rigid fruit cages all protect crops without entanglement risk. For training climbing plants, [natural fiber plant ties](https://gardenerexpert.com/category/garden-twine/) are a zero-hazard replacement for netting across most vegetable growing situations.
