How to Help Hedgehogs in Autumn: A Practical Garden Guide

Autumn is an important season for Britain’s hedgehogs. As nights become longer and temperatures fall, they spend more time feeding and looking for secure places to nest. Hibernation does not begin on a fixed date: weather, food availability and the condition of each animal all play a part, so hedgehogs may remain active well into late autumn or reappear during mild winter spells.

You do not need to transform the whole garden to help. Suitable food, clean water, safe shelter and a few careful gardening habits can make a meaningful difference. This practical checklist explains how to support visiting hedgehogs responsibly without disturbing their natural behaviour.

Why do hedgehogs need extra support in autumn?

Hedgehogs naturally eat beetles, caterpillars, earthworms and other invertebrates. During autumn they feed intensively as they prepare for hibernation, but natural food can become harder to find as temperatures fall. Habitat loss, enclosed gardens and the use of pesticides can also reduce both feeding areas and safe routes between them.

Supplementary feeding should support rather than replace natural foraging. A garden with leaf litter, log piles, varied planting and connected boundaries remains one of the best long-term resources you can provide.

1. Offer suitable hedgehog food

Put out a small portion of specialist hedgehog food in the evening. Meat-based wet cat or dog food and crushed meat-based cat or dog biscuits are also commonly recommended when specialist food is unavailable. Use a low, stable dish that a hedgehog can reach comfortably.

Remove uneaten wet food the following morning and replace it with a fresh portion the next evening. This helps prevent spoilage and discourages flies, rodents and other unwanted visitors.

Never offer milk or bread. Hedgehogs are lactose intolerant, while bread provides little useful nutrition. Avoid salty, sugary or seasoned human food, and do not leave discarded pumpkin on the ground for wildlife.

2. Provide fresh water every night

Fresh water is just as important as food. Leave a shallow dish of clean water near the feeding area and check it every day, even during cool or wet weather. Hedgehogs may wake during mild winter periods and will benefit from water being available when they do.

Clean feeding and drinking dishes daily outside—not in the kitchen—using hot, soapy water, then rinse them thoroughly. Regular cleaning reduces the risk of illness spreading between animals that visit the same feeding point.

3. Create a quiet, dry shelter

A hedgehog may build a winter nest beneath a hedge, inside a log or leaf pile, under decking or in dense vegetation. Leaving one undisturbed corner of the garden slightly untidy can therefore be extremely useful.

A purpose-made hedgehog house provides another option. Position it in a quiet, shaded and sheltered location, ideally close to a hedge or shrubs. Face the entrance away from prevailing wind and avoid placing it where the ground regularly becomes waterlogged.

Leave dry leaves nearby so a hedgehog can gather its own nesting material. Keep food and water away from the sleeping area, as spills, damp and visiting animals can make a nest less secure. Once a house is occupied, resist the temptation to lift the lid or repeatedly check inside.

4. Connect your garden with a hedgehog highway

Hedgehogs can travel considerable distances at night while searching for food, shelter and mates. Solid fences and walls divide gardens into isolated spaces, forcing animals towards roads or preventing them from reaching useful habitat.

A gap measuring approximately 13cm by 13cm at the bottom of a fence or gate is large enough for a hedgehog to pass through. Where possible, coordinate with neighbours so several gardens form a connected route. Check that openings have smooth edges and do not lead directly onto a dangerous road.

5. Carry out an autumn garden safety check

Many ordinary gardening jobs become hazardous when hedgehogs are nesting in long grass, fallen leaves or piles of garden material. Before tidying, take a few moments to check the area carefully.

• Strimmers and mowers: inspect long grass, hedge bottoms and overgrown edges by hand before cutting.
• Bonfires: build or move the pile on the day it will be lit, checking carefully for wildlife first. Light from one side so any hidden animal has an escape route.
• Compost heaps: check before turning or inserting a garden fork.
• Ponds and pools: provide a sloping edge, ramp or securely fixed escape route.
• Drains and holes: cover them or provide a way for trapped wildlife to climb out.
• Netting: keep loose garden and sports netting raised above ground level.
• Pesticides and slug pellets: avoid them where possible; they reduce the invertebrates hedgehogs naturally eat and may introduce additional risks.

Leaving a section of leaf litter and dead stems in place also supports insects, providing a more natural source of food. You can read more about seasonal changes in our guide to wildlife signs of autumn in September.

6. Watch without disturbing

Footprints, droppings, disturbed leaves and quiet snuffling after dark can all suggest hedgehog activity. If you want to find out which animals are visiting, a discreet hedgehog or wildlife camera can help you observe them without opening a shelter or approaching a feeding area.

Avoid bright lights, flash photography and unnecessary handling. Hedgehogs are wild, predominantly nocturnal animals and should be allowed to forage and nest with as little interruption as possible.

What if a hedgehog is active in winter or during the day?

A hedgehog appearing at night during a mild winter spell is not automatically in trouble. Continue to provide food and water and observe from a distance.

Daytime activity can have several explanations, but seek advice promptly if the hedgehog is lying exposed, staggering, circling, visibly injured, surrounded by flies or showing repeated unusual behaviour. Do not attempt long-term care yourself. Contact the British Hedgehog Preservation Society on 01584 890 801, a local wildlife rescue or a vet for guidance.

Autumn hedgehog-care checklist

• Put out suitable food after dusk.
• Provide fresh water in a shallow dish.
• Wash bowls outside every day.
• Leave a quiet, dry nesting area undisturbed.
• Create a 13cm by 13cm route between gardens.
• Check carefully before mowing, strimming, turning compost or lighting a bonfire.
• Make ponds, drains and netting safer.
• Ask a wildlife rescue or vet for advice if an animal appears injured or unwell.

Small, consistent actions are more valuable than a one-off intervention. By combining natural habitat with safe supplementary food, water and shelter, you can make your garden a more useful stopping place throughout autumn and beyond.
