Hedgehogs are one of the most recognisable mammals to visit British gardens after dark, often covering a surprising distance, sometimes a mile or more, over a single night as they forage. A Garden Wildlife UK that offers a route in, something to eat and somewhere quiet to rest is far more likely to see repeat visits than one that is sealed off and tidied within an inch of its life.

Design details matter more than they might appear to. Good insect houses combine hollow stems, such as bamboo or reed, with drilled wood blocks offering a range of hole diameters, roughly 2 to 10mm, since different species use different sized cavities. Natural, untreated materials are preferable to anything varnished or chemically treated.

Hedgehogs typically hibernate through the coldest months, often in piles of leaves, log stacks, or purpose-built shelters tucked into a quiet corner. Anything resembling a bonfire pile should always be checked carefully before lighting, since it can look like an ideal hibernation spot to a hedgehog settling in for winter.

Food choice should shift with the seasons. High-fat foods such as fat balls and suet blocks suit the colder months, when birds need extra energy to maintain body heat. During the breeding season, softer foods and mealworms are more useful, since adult birds feed these to chicks that cannot yet manage tougher foods. Sunflower hearts work well year round and avoid the mess of husks left by whole sunflower seeds.

Different nematode species target different problems. Some are used against slugs, others against vine weevil grubs feeding on plant roots in containers and borders, and others against chafer grubs or leatherjackets damaging lawns. Because they are pest-specific, the right choice depends on identifying which pest is actually causing the damage.

Winter care is really about restraint. Amphibians often spend the coldest months dormant in mud at the pond bottom, so the pond is best left undisturbed rather than cleared out or heavily managed during this period. If the surface freezes over, gently melting a small area with warm water is a gentler approach than breaking the ice directly above where they may be sheltering.
