Understanding Hedgehog Needs
When considering how to look after hedgehogs, the primary aim is to support their natural behaviours and survival, particularly if they appear to be struggling or if you wish to encourage them in your garden. These fascinating mammals are nocturnal insectivores, primarily foraging for beetles, worms, slugs, and other invertebrates. In the wild, they construct nests from leaves and grass, often in dense undergrowth, log piles, or compost heaps, and require access to water sources for drinking and bathing. Providing these basic provisions can make a significant difference to their well-being.
- Offer supplementary food and fresh water.
- Create safe, sheltered nesting sites.
- Avoid common garden hazards.
- Recognise signs of distress or illness.
It's important to remember that while supplementary feeding can be beneficial, it should be done responsibly. The goal is to assist, not to create dependency or to feed them unsuitable items. Understanding their natural diet and habitat preferences is the first step in providing effective care. While the total number of hedgehogs in the UK has declined significantly, creating a hedgehog-friendly garden is a rewarding way to contribute to their conservation efforts.
Dietary Considerations for Garden Visitors
When deciding how to look after hedgehogs with food, offering a small amount of high-quality, supplementary food can be a valuable aid, especially during dry spells or when natural food sources are scarce. Suitable options include specialised hedgehog food, or a small amount of meaty cat or dog food (not fish-based). Avoid milk, as hedgehogs are lactose intolerant and it can cause severe digestive upset. Similarly, bread offers little nutritional value and can be harmful. It is crucial to ensure that any food provided is placed in a shallow dish, ideally within a feeding station designed to prevent larger animals like foxes or cats from accessing it, and only a small quantity should be offered each evening to avoid wastage and deter pests. Always ensure fresh, clean water is available alongside food.
Water Sources and Hygiene
A constant supply of fresh water is as vital as food for hedgehogs. They need it for drinking, especially during warmer months, and they also use it for bathing, which helps to keep their spines clean and free from parasites. A shallow dish or a purpose-built water source in your garden can be a lifeline. Ensure the dish is easily accessible but not too deep, perhaps with stones or pebbles placed inside to provide a safe exit route should a hedgehog fall in. Regularly clean the water dish to prevent the build-up of algae and bacteria, which could otherwise make the water harmful. Maintaining good hygiene around feeding and watering stations is paramount to preventing the spread of disease among garden visitors.
Place a shallow dish of water in a safe spot away from potential predators and ensure it has an escape route with pebbles or a ramp.
Identifying Wild Hedgehogs
Recognising when a hedgehog might need assistance is a key part of learning how to look after them. While hedgehogs are nocturnal and often appear briefly at dusk or dawn, seeing one during daylight hours could indicate a problem, especially if it appears lethargic, distressed, or injured. Hedgehogs typically weigh between 400-1200 grams depending on the season; a hedgehog weighing less than 400 grams in late autumn may be too light to survive hibernation. If you encounter a hedgehog that seems unwell, injured, or is active during the day when it shouldn't be, it's advisable to seek expert advice. Do not attempt to handle it extensively without guidance.
Creating a Hedgehog-Friendly Garden Environment
Transforming your garden into a safe haven is a fundamental aspect of knowing how to look after hedgehogs, ensuring they have the resources and protection they need to thrive. This involves managing your garden in a way that minimises dangers and maximises opportunities for foraging and nesting. Making small, thoughtful changes can create a sanctuary for these declining native mammals.
Safe Havens and Nesting Sites
Hedgehogs require safe places to rest and nest during the day and to hibernate during winter. Natural options are best. Consider creating a log pile in a quiet corner of your garden, leaving dense, undisturbed patches of undergrowth, or a well-managed compost heap. If you are building a new compost heap, try to include a space at the bottom that is accessible from the sides to allow hedgehogs entry. Purpose-built hedgehog houses can also provide excellent shelter, especially during hibernation. These should be placed in a sheltered, quiet location, ideally facing away from prevailing winds and rain, and covered with a thick layer of leaves and soil to provide insulation.
Garden Hazards to Avoid
When planning how to look after hedgehogs, identifying and mitigating common garden hazards is critical. Garden tools such as strimmers and lawnmowers can cause severe injuries to hedgehogs, especially if they are nesting or resting in long grass. Always check long grass, compost heaps, and under sheds before using such equipment. Open drains, ponds without shallow access points, and netting can also pose significant risks. Ensure ponds have a ramp or sloping edge so hedgehogs can escape if they fall in, and be mindful of where you place garden netting, as they can become entangled. Holes in fences or walls should be at least 13cm x 13cm to allow hedgehogs to pass through freely between gardens, as they often travel considerable distances each night.
The most impactful way to care for hedgehogs is to provide them with continuous access to safe passage through gardens and to remove common, preventable dangers.
Alternative Ways to Provide Shelter
While natural nesting sites are ideal, if your garden lacks suitable dense cover, you can create artificial shelters. A simple hedgehog house can be made from untreated timber, with an entrance hole of approximately 13cm x 13cm. It should have a slightly sloped roof to allow water runoff and a removable lid for cleaning. Position it in a secluded spot and camouflage it with leaves and twigs. Another alternative is to create a habitat pile using logs, branches, and leaf litter, ensuring it is stable and offers multiple entry and exit points. These alternative structures offer a secure, dry environment for resting and hibernation.
When constructing a hedgehog house, ensure the internal floor space is large enough for them to turn around comfortably, typically around 30cm x 40cm.
When to Seek Expert Help
Understanding how to look after hedgehogs also includes knowing when your intervention might be necessary and when to defer to wildlife rescue professionals. While the instinct to help is admirable, it's crucial to distinguish between a hedgehog that is simply active at night and one that is genuinely in distress or danger.
Recognising Signs of Injury or Illness
Several indicators suggest a hedgehog needs expert care. These include visible injuries such as wounds, bleeding, or broken limbs. Lethargy, particularly if observed during daylight hours, is a significant concern. Hedgehogs that are underweight for the time of year are also at risk; a general guideline is that they should weigh over 400 grams by late autumn to have a good chance of surviving hibernation. If a hedgehog is staggering, appears disoriented, has flies buzzing around it (which can indicate maggans), or is struggling to curl into a ball, it likely requires immediate professional attention. Observing these signs means it is time to consider contacting a specialist.
Contacting Wildlife Rescues
If you suspect a hedgehog needs help, the first step is to contact a local wildlife rescue organisation. Many reputable charities and centres specialise in caring for injured and orphaned hedgehogs. They have the expertise, facilities, and medication to provide the best possible care. When you call, be prepared to provide details about the hedgehog's condition, where you found it, and its approximate weight if you have been able to ascertain it safely. The rescue centre will advise you on the next steps, which may involve bringing the animal to them or following their specific care instructions under their guidance. They are the definitive source for information on how to look after hedgehogs that are in trouble.
Temporary Care Guidelines
In some instances, a wildlife rescue may advise you to provide temporary care until you can transport the hedgehog. This might involve keeping the animal in a secure, quiet, dark place, such as a high-sided plastic box lined with newspaper and a soft towel or old T-shirt. Provide a shallow water dish and a small amount of appropriate food, such as meaty cat food or specialist hedgehog food. Ensure the box is placed in a warm, draft-free location, but not directly on a heat source. Avoid handling the hedgehog more than absolutely necessary, as stress can exacerbate its condition. Remember that this is a short-term measure; the ultimate goal is to get the hedgehog to professional care as soon as possible.
Alternatives to Direct Intervention
If hedgehogs in your area seem healthy and are active at night, the best way to look after them is often through indirect support. This involves creating a hospitable environment as detailed previously – providing food and water if needed, ensuring safe passage, and avoiding garden hazards. Sometimes, the most effective care is simply to allow them to live their lives undisturbed. If you are concerned about long-term population health, consider supporting local wildlife charities that work on hedgehog conservation projects. These organisations often engage in habitat restoration and public awareness campaigns, offering a broader approach to hedgehog welfare beyond individual garden care.
Encouraging Natural Foraging and Hibernation
Beyond supplementary feeding and immediate rescue, a crucial element of how to look after hedgehogs is fostering their natural behaviours, particularly foraging and successful hibernation. These are vital for their long-term survival and population health.
Supporting Natural Food Sources
While supplementary food can be a lifeline, encouraging natural foraging is paramount. Hedgehogs rely on a diet of invertebrates, and the health of your garden's ecosystem directly impacts their food supply. Reducing the use of pesticides and slug pellets is essential, as these chemicals can poison hedgehogs directly or indirectly by depleting their food sources. Promoting biodiversity by planting native wildflowers and creating areas of longer grass or leaf litter can attract a wider variety of insects, worms, and slugs, providing a more natural and abundant larder for visiting hedgehogs. Consider creating insect hotels or leaving areas of your garden slightly 'wild' to support this.
Facilitating Safe Passage
Hedgehogs often need to travel across several gardens to find food, mates, and hibernation sites. A significant barrier to their movement is fencing and walls. If you have solid fencing, consider creating hedgehog highways by cutting holes (at least 13cm x 13cm) in the bottom of fences, or by talking to neighbours to establish connected routes. This connectivity is vital for maintaining healthy, diverse populations and allowing individuals to access necessary resources. Without these corridors, hedgehogs can become isolated, making them more vulnerable to local extinction and reducing genetic diversity.
Preparing for and Monitoring Hibernation
Hibernation is a critical period for hedgehogs, typically lasting from November to April. During this time, they rely on well-constructed, undisturbed nests. As autumn approaches, ensure your garden offers suitable hibernation locations like dense undergrowth, log piles, or the base of thick hedges. Avoid tidying up too much in late autumn; leave leaf litter and debris in quiet corners where they are unlikely to be disturbed. If you find a hedgehog attempting to hibernate in a dangerous location, such as a compost heap that is about to be turned or a pile of garden waste that will be moved, carefully relocate it to a more secure, quiet spot nearby. Do not disturb hibernating hedgehogs unless absolutely necessary, as waking them expends vital energy reserves.
When creating a hibernation site, ensure it is sheltered from wind and rain and that any entrances are not easily accessible to predators like foxes.
The Role of Feeding Stations
A well-designed feeding station can be a vital component of how to look after hedgehogs, particularly during dry periods or lean seasons. These stations protect food from larger animals and deter pests. A simple DIY feeding station can be constructed using a wooden box with an entrance tunnel, large enough for a hedgehog but too small for foxes or badgers. Alternatively, commercially available feeding stations offer a robust solution. Placing these stations in a quiet, sheltered part of the garden, away from human activity, will increase the chances of hedgehogs using them regularly and safely. Remember to clean them regularly to maintain hygiene.
