Hedgehogs are among the most welcome visitors to Oxfordshire's suburban gardens, yet their numbers have fallen sharply across the UK. In towns like Witney, Thame, and the outskirts of Oxford, these nocturnal creatures still navigate our lawns and borders after dark. Understanding their activity is the key to giving them a helping hand.

A Year in the Life of a Suburban Hedgehog

Hedgehogs emerge from hibernation in March or April, depending on the weather. In Oxfordshire, they are most active from April to October. At dusk, they begin their rounds, searching for food. A single hedgehog can travel up to two kilometres in a night, often crossing several gardens. They do not hibernate until November or December, when temperatures drop and their natural food becomes scarce. Before that, they must build up fat reserves – a hedgehog weighing under 600 grams in late autumn may struggle to survive the winter. Suburban gardens offer a patchwork of habitats: lawns full of earthworms, flower beds with beetles, and compost heaps teeming with insects. But these resources are only useful if hedgehogs can reach them.

What Brings Hedgehogs to Your Garden

Hedgehogs are opportunistic feeders. Their favourite natural foods include beetles, caterpillars, earthworms, and slugs. A garden that is rich in these invertebrates will naturally attract them. However, many modern gardens are too tidy. Short, manicured lawns, paved driveways, and sealed fences create barriers. Hedgehogs need wild corners – areas where leaves are left to rot, logs are stacked, and grass grows a little longer. These places provide both food and shelter. They also need access. A small gap in a fence or wall, just 13 centimetres wide, is enough to let a hedgehog through. This simple measure, often called a hedgehog highway, can transform a suburban street into a connected network of gardens.

Practical Steps to Encourage Hedgehogs

Helping hedgehogs is surprisingly easy. Start by leaving a patch of your garden undisturbed. Then add a few key features:

• Log piles and leaf litter: These attract beetles and provide nesting sites.
• A compost heap: Ideal for foraging, but always check for sleeping hedgehogs before turning it.
• A shallow water bowl: Hedgehogs get thirsty. Use a bowl no more than 5 centimetres deep, and add a few stones so they can climb out if they fall in.
• A hedgehog house: A simple wooden box with a tunnel entrance can offer a safe place to rest or hibernate.
• Gaps in fences: Create a 13 cm hole at ground level, or dig a small trench under a gate.

These small changes make a big difference. In suburban Oxfordshire, a single garden can support several hedgehogs if it provides food, water, and shelter.

Water, Food, and What to Avoid

If you want to supplement a hedgehog's natural diet, offer meat-based cat or dog food or specially formulated hedgehog food. Never give them milk or bread – hedgehogs are lactose intolerant, and milk can cause serious digestive problems. Bread has little nutritional value. Also avoid:

• Slug pellets: Metaldehyde is lethal to hedgehogs. Use nematodes, beer traps, or hand-picking instead.
• Poisons and pesticides: These reduce insect numbers and can poison hedgehogs directly.
• Plastic netting: Hedgehogs can become entangled. Store it well above ground.
• Bonfires: A pile of wood is an irresistible shelter. Always move it before lighting, or rebuild it on the day.

Fresh water is essential year-round, but especially in hot weather and during lactation. A shallow bowl refreshed daily will be much appreciated.

Spotting Hedgehog Activity Without Disturbing Them

Hedgehogs are shy and nocturnal. The best time to look is just after dusk, when you might hear rustling or snuffling. A torch with a red filter lets you observe without causing stress. Look for signs:

• Droppings: Dark, cylindrical, and shiny, often full of insect fragments.
• Trails: Flattened grass or disturbed soil along fences and borders.
• Nests: A dome of leaves and moss, usually hidden under a shed or in a hedge.

If you have a camera trap, set it low to the ground near a known path. Avoid handling hedgehogs unless they are in danger. If you find one out in daylight, it may be unwell – contact a wildlife rescue for advice.

Helping Hedgehogs Through the Seasons

Hedgehog needs change with the seasons. In spring, they wake hungry and thirsty. Keep water bowls filled and leave wild corners undisturbed. In summer, breeding females need extra food. Avoid mowing long grass without checking first. In autumn, hedgehogs are building fat reserves. Supplementary feeding helps, but stop if it attracts rats. In winter, hibernating hedgehogs are vulnerable to disturbance. Leave log piles and compost heaps alone. If you find a hedgehog out in freezing weather, it may need help. Weigh it – if it is under 600 grams, it may not survive. Contact a local wildlife rehabilitator. By understanding their rhythm, Oxfordshire gardeners can make a real difference to these charming creatures.
