How to Attract Hedgehogs into a Small Garden

Why Hedgehogs Need a Hand

Hedgehogs are one of the most beloved creatures in the British countryside, and yet their numbers have fallen sharply in recent decades. The reasons are many and mostly man-made: tidy gardens, solid fences, busy roads, the loss of hedgerows and the widespread use of slug pellets. A small garden might not seem like it can make much difference, but it can. Gardens together cover more land than all our nature reserves combined, and a network of small, hedgehog-friendly plots can act as a lifeline for a local population.

The good news is that you do not need acres of wildflower meadow or a bottomless budget. Hedgehogs ask for three things: a safe route in, somewhere quiet to sleep, and clean water to drink. Get those right and you may well find a prickly visitor snuffling about after dusk.

Open Up a Hedgehog Highway

A hedgehog can travel up to two miles in a single night in search of food and a mate, but it cannot climb a six-foot fence panel. For many urban and suburban hogs, solid boundaries are the single biggest obstacle. The answer is a hedgehog highway — a simple gap, roughly 13cm by 13cm (about the size of a CD case), cut into the bottom of a fence or wall.

If you cannot cut your fencing, a few alternatives work just as well:

• Lift a fence panel and rest it on a couple of bricks, creating a gap along the base.
• Dig a small tunnel beneath a gravel board and line it with a short length of pipe.
• Leave a border of loose soil or gravel alongside a wall so hogs can push underneath.

Talk to your neighbours. A highway only works if it connects. If three or four gardens on your street each cut one gap, you have created a corridor that lets hedgehogs move safely between feeding grounds without ever stepping onto the road. That single conversation over the garden fence can be one of the most valuable things you do for local wildlife.

Build a Quiet Corner

Hedgehogs are nocturnal and nervous. They need somewhere dark, dry and undisturbed to sleep through the day, and somewhere sheltered to hibernate between November and March. The tidiest garden offers very little. A wild corner — even a small one — is worth its weight in gold.

A simple hedgehog house is easy to make or buy. Site it against a wall or fence, facing away from the prevailing wind (south or south-west is ideal in the UK), and cover it with a layer of leaves or a piece of old roofing felt for extra waterproofing. Inside, line it with dry leaves and hay — never use hay alone if it might get damp, as it can go mouldy. Avoid the temptation to check on your resident too often; a quiet peek in autumn is plenty.

If you would rather not buy or build, a pile of logs, a stack of leaves under a hedge, or a brash pile in a shady border will do the job nicely. The key is to leave it alone. Resist the urge to tidy it in spring until you are sure nothing is sleeping inside.

Food, Water and a Little Wildness

Hedgehogs are insectivores, and a garden full of beetles, caterpillars, earwigs and earthworms is their ideal larder. You can boost the natural food supply by:

• Leaving a patch of long grass, ideally with a wildflower mix, to support insects.
• Keeping a log pile or leaf litter in a damp corner.
• Avoiding slug pellets and other pesticides, which are lethal to hedgehogs as well as to their prey.
• Planting native shrubs such as hawthorn, blackthorn or hazel for nesting and cover.

If you want to offer supplementary food, meat-based dog or cat food in jelly (not gravy, which can upset their digestion) or a purpose-made hedgehog food is best. Put it out after dusk in a shallow dish. Never give them bread or milk — hedgehogs are lactose intolerant and milk can make them seriously ill.

Water matters just as much. A shallow dish of fresh water, refreshed daily, is one of the simplest gifts you can give. It also supports birds, bees and other garden visitors. If you have a pond, make sure it has a gently sloping edge or a ramp of stones so a hedgehog that falls in can climb back out. A steep-sided pond is a death trap.

Keep Them Safe from Everyday Dangers

A hedgehog-friendly garden is also a safer garden. There are a few hazards worth dealing with before you welcome your first visitor.

• Ponds and drains: add escape ramps and cover open drains with mesh.
• Netting: keep fruit netting and pea netting well above ground level, as hogs become badly tangled.
• Strimmers and mowers: check long grass before cutting, especially in spring and autumn.
• Bonfires: rebuild in a new spot on the day you intend to light it, or lift the whole pile first. A hibernating hedgehog is easy to miss.
• Slug pellets and rat poison: these travel up the food chain and kill hedgehogs. Use beer traps or hand-picking instead.

Finally, remember that hedgehogs are wild animals. If you find one out in daylight, especially in winter, or one that looks unsteady, it is probably in trouble. Contact a local wildlife rescue for advice rather than trying to treat it yourself.

A Small Garden Can Make a Big Difference

Attracting hedgehogs is really about letting a little wildness back in. A 13cm gap in a fence, a quiet corner left to itself, a dish of water and a pledge to garden without poisons — that is all it takes. Do these things and you may not see a hedgehog for weeks, because they are shy and mostly silent. But the tell-tale snuffles in a border at dusk, or a small dark shape shuffling across the lawn, will more than reward your patience. And if your neighbours join in, your street becomes part of something far bigger: a quiet, connected refuge for one of Britain's most charming and most vulnerable creatures.
