In brief: A hedgehog-friendly garden fence leaves a safe gap of at least about 10 x 10 centimetres at ground level. Remove sharp wire ends, secure gates and connect your garden with neighboring properties. You can also protect hedgehogs with hiding places, shallow water bowls and by avoiding poison, robotic lawn mowers at night and open traps.
A garden fence separates properties, but it should not prevent hedgehogs from moving through their habitat. At night, these animals search for beetles, worms and other food, moving between gardens, hedgerows and green spaces. A small gap at ground level keeps this route open.
When it comes to wildlife protection in the garden, the entire property boundary matters. A single open section of fence is of little use if the next gate, a concrete wall or a dense privacy screen blocks the way. Plan your fence, posts and garden accessories with the surrounding area in mind, and find suitable options in the garden and outdoor range.
Why does a hedgehog need a permeable garden fence?
Hedgehogs travel widely through their surroundings in search of food. Hedgerows, gardens and unpaved verges form one connected territory for them. A solid fence interrupts these routes and forces the animals to take detours across roads or into dangerous areas.
A gap at ground level creates a safe connection. It must remain open permanently and must not lead directly to a road, steep drop or open building trench. Where possible, coordinate the opening with your neighbors so that a single passage becomes a genuine corridor for wildlife in the garden.
- Clear bottom edge: Keep the passage level with the ground and free from roots, stones and bark mulch.
- Smooth edges: Bend over wire ends or cover them with a sturdy, smooth profile.
- Short routes: Lead the passage toward hedges, flower beds or another sheltered area.
- No traps: Avoid dead ends near basement window wells, ponds or steep walls.
Pro tip
Mark the planned passage with two stakes before putting up the fence. This keeps the opening at the same height even when the wire is tensioned and prevents it from disappearing behind soil, bark mulch or a lawn edge.
How large should the gap in a garden fence be?
Plan for at least 10 x 10 centimetres of clear space at the bottom of the fence. This size allows many hedgehogs to pass through without requiring you to build the entire fence low. On a slope, measure at the narrowest point, not at the highest visible point of the ground.
The passage does not need a complicated flap or a long tunnel. An open, clearly visible spot is usually the best solution. Do not use sharp-edged pipe sections, and do not narrow the route with planters, stones or dense roots.
How to create the opening correctly
- Prepare the ground: Remove loose stones and compact the ground so that the opening does not become smaller after just a few weeks.
- Check the measurements: Check the height and width with a sturdy template or tape measure.
- Secure the edges: Attach wire, wood or metal so that no sharp points protrude into the passage.
- Keep the surroundings clear: Leave some space for the animals on both sides and keep the access free from tools.
Do not place the passage in the brightest part of the garden. An edge beneath a hedge or beside a flower bed feels more sheltered to nocturnal animals. After rain, frost and gardening work, check whether soil or mulch has blocked the route.
“It is prohibited to wilfully disturb wild animals or to capture, injure or kill them without good reason.”
Which types of garden fencing are hedgehog-friendly?
When choosing between different types of garden fencing, the material alone does not determine how safe a fence is for hedgehogs. A safe bottom edge, secure fixings and a clear passage without trapping hazards are all important. Any type of fence can be made hedgehog-friendly if you plan a route through it from the start.
Chain-link and aviary wire
Chain-link fencing works well for long property boundaries because it is easy to add individual openings. Avoid tensioning the mesh so low that loose loops form at ground level. Do not simply cut off protruding wire ends; bend them towards the inside of the fence or cover them with a smooth guard.
Check the bottom edge carefully after installation, especially with close-mesh wire fencing. Small mesh openings will not help hedgehogs if the fence reaches the ground. Keep the planned passage clear and make sure no additional tension wire blocks it.
Wooden and metal fences
A picket fence can let hedgehogs through as long as there are no narrow gaps between the slats where they could get trapped. A horizontal board at ground level, on the other hand, creates a continuous barrier. Leave a clearly defined opening in one or more places and sand down any rough edges.
With metal fences, pay particular attention to post bases, ground anchors and crossbars. These can create small gaps where paws or spines may get caught. A stable passage with a smooth frame offers better protection than an accidental gap.
Privacy screens and solid fence panels
A solid-panel privacy fence completely separates gardens unless you plan an opening at ground level. Before cutting an opening in a load-bearing panel, check that it will remain stable. A better option is to install a separate, smooth passage panel between two posts.
These products from our range may suit your fence design:
- : Green aviary wire measuring 10 x 1.5 metres, ideal for a see-through mesh fence.
- : Green aviary wire measuring 10 x 1.68 metres, a taller fencing option.

Whichever product you choose, the bottom edge is still key. You can find additional posts, fixings and protective profiles in our garden equipment section.
Important note
Do not use barbed wire, and do not tension wire mesh down to ground level if this creates loops. Hedgehogs can become caught by their spines or legs. Do not simply cut off wire ends; bend them over and secure them with a smooth cover.
How do you make gates, corners and fence ends hedgehog-friendly?
Many fences are passable along their main sections but block hedgehogs at gates and property corners. Check the entire boundary, not just the fence panels. Measure the gap from the ground with the gate closed and in every position where it is often left open.
Gates and garden gates
A gate needs a permanent passage on a sheltered side. Leave at least 10 x 10 centimetres of clearance and make sure a gate stop or latch does not cover the opening. If the gate opens towards the road, place the passage on the side or rear boundary of the property.
Take extra care with automatic gates and heavy garden doors. A hedgehog could become trapped beneath a slowly closing gate if the gap is too small. Make sure the door cannot slam shut and that the passage stays clear when the gate is open.
Corners, walls and changes in level
At a corner, the fence often meets a wall or the side of a house. Do not seal this junction completely if it blocks the only route between two green spaces. Run the passage along the wall and remove any mortar, nails or sharp fixings.
On sloping ground, the passage height changes from one metre to the next. Check the lowest point after heavy rain and after adding soil. A small step made from stone or wood can stabilise the transition, but must not make the passage narrower.
Connecting to a neighbour's garden
Discuss the planned passage with your neighbours. Otherwise, an open route may end at the next completely closed boundary. A few coordinated openings help hedgehogs more than lots of isolated passages.
For work on posts, wire and edging, you can find suitable garden tools. Work carefully and check after each repair for new sharp edges or narrow gaps.
Additional advice
Photograph the fence once a month from ground level. These pictures can help you spot sunken soil, overgrown passages and protruding wires faster than an inspection from eye level.
What does a hedgehog need besides a garden fence?
A passage is only useful if the yard also offers safe places to hide. Hedgehogs need dense plants, leaves, branches, and undisturbed areas where they can sleep during the day. Leave at least one corner a little wild, with natural materials for cover.
Water and food
During dry weather, set out a shallow bowl of fresh water. A heavy bowl is less likely to tip over. Place it somewhere a hedgehog can reach easily, and change the water and clean the bowl regularly.
Healthy hedgehogs don’t usually need extra food. Milk, bread, and seasoned foods can harm them. If you need to care for a weakened hedgehog, contact a wildlife expert first. You can find information and suitable products in our hedgehog food section.
Hiding places and natural routes
Hedges, leaf piles, and loosely stacked branches provide shelter. Leave clear paths between these hiding places. Ground cover shouldn’t grow over the fence opening and make it hard for hedgehogs to find.
Open compost piles attract insects, but they can also pose a hazard. Secure deep containers and place boards inside to give animals a way out. Cover rain barrels, shafts, and unused openings before leaving the yard at night.
Pesticides, nets, and garden tools
- Avoid slug pellets and chemical products when a mechanical or biological solution will work.
- Remove loose nets after use, or stretch them tightly well above the ground.
- Check leaf and brush piles before moving or burning them.
- Cover construction pits, cable shafts, and deep containers right away.
- Don’t use string trimmers or brush cutters blindly in tall grass or beneath hedges.
Robotic lawn mowers pose a particular danger to hedgehogs at night and at dusk. Run them only during daylight, and check the lawn before starting the mower. Leave the areas beneath the fence, including borders, leaf piles, and dense hedges, as undisturbed as possible.
How can you keep a fence hedgehog-friendly over time?
A hedgehog-friendly fence needs regular checks. Soil shifts, roots grow, and animals or yard work can loosen fasteners. Check the fence line after storms, frost, construction work, and major pruning.
Check and repair
- Make sure the passage is still the same height and width.
- Clear grass, leaves, stones, and mulch from the entrance.
- Secure loose posts and replace rusty or broken parts.
- Bend back or remove protruding wire ends right away.
- Check the back of the fence, too. It’s often out of sight from the house.
Include children and other helpers in your checks. A quick look at ground level can prevent plant baskets, boards, or tools from accidentally blocking the passage. During major yard work, mark the opening with a clearly visible sign.
Plan the yard as a connected space
A good garden fence protects beds and pets while still letting wildlife pass through. Add several openings if the yard is long or a corner blocks the route. Connect them with hedges, perennial plants, or a narrow strip of greenery.
“It is prohibited to pursue, capture, injure or kill wild animals of specially protected species, or to remove, damage or destroy their developmental forms from the wild.”
This legal protection shows why planning your fence with wildlife in mind matters. Leave the lower edge open, reduce hazards, and keep the passages clear all year. That way, your garden fence stays sturdy and practical while remaining accessible to hedgehogs.
Frequently Asked Questions
- How big should an opening in a garden fence be for hedgehogs?
- Leave at least approximately 10 x 10 centimetres of clear space at the bottom of the fence. The opening should be level with the ground, free of sharp edges, and accessible year-round. Check gates, wall bases, and neighboring property lines, too, so a hedgehog won’t get stuck at the next barrier.
- What type of garden fence is hedgehog-friendly?
- Wire mesh, wood, and metal fences can all work if they have a smooth lower edge or a safe opening. The material matters less than leaving a gap above the ground. Avoid barbed wire, loose nets, and sharp wire ends. Secure every corner and gate.
- Can you feed hedgehogs in your yard?
- Healthy hedgehogs don’t usually need food. During dry weather, provide a shallow bowl of water. In an emergency, high-quality cat or dog food without gravy is suitable. Never give hedgehogs milk or bread. Contact an expert about injured, listless, or daytime-active animals.
- Are robotic lawn mowers dangerous for hedgehogs?
- Yes, especially at night and at dusk. When threatened, hedgehogs don’t reliably run away; they curl into a ball. Run a robotic lawn mower only during the day, check the mower and lawn first, and leave leaf piles, hedge borders, and other hiding places undisturbed.
- How can I keep hedgehogs from getting injured by a garden fence?
- Check the fence regularly for open mesh, protruding wires, and narrow gaps. Leave a clear opening at ground level instead of making hedgehogs dig underneath. Cover construction pits, remove loose nets, and secure water containers with a way for animals to escape.
