Why every garden needs a hedgehog house – and how to attract hedgehogs

Hedgehogs are increasingly rare – but they are our best friends for natural pest control

With their spiky bodies and snuffly noses, there is something undeniably cute about the humble garden hedgehog. While they were once a common sight in UK gardens, they are now increasingly rare.

So rare in fact that they were recently classed as vulnerable to extinction - so it's never been so important to help them. According to the Wildlife Trusts there were 1.5 million hedgehogs in 1995 while today it is believed that there are fewer than 500,000.

The sharp decline in numbers is due to myriad factors, from loss of habitat due to urbanization and deforestation, as well as a loss of food because of the increased use of pesticides both in commercial farming and in domestic gardens. 

'Hedgehogs are becoming incredibly rare,' says gardening guru Monty Don. 'If you find one in your garden you must look after it.' 

'Building a hedgehog house provides a safe, warm space for a hedgehog to sleep, give birth or hibernate' says expert Sally Coulthard in her book  The Hedgehog Handbook

Hedgehogs to use hedgehog houses, and they offer them offer valuable protection, whether they are hibernating through winter or just sleeping through the day. This is particularly important given the loss of natural habitat they've been facing, which leaves them vulnerable to the elements and prey. 

Hedgehogs are great for the garden – they eat a wide variety of garden pests, slugs and snails being favorite meals. Using slug pellets not only eradicates this vital food source, but can also prove fatal to hedgehogs if consumed, so instead protect plants overnight by covering them, creating beer traps, using copper tape or eggshells. With time, the hedgehogs (and other predators like birds) will be all the slug control you'll need.

What is the best house for a hedgehog?

There are lots of options for choosing the best hedgehog house.

It is very easy to build your own. There are lots of hedgehog house plans available online to teach you how to create a wooden house. Alternatively you can quickly create a hedgehog house by cutting a door and two rectangular air-vents in an old plastic storage container and filling it with dry leaves.

If you want a more professional addition there are countless styles available in garden centres and from wildlife charities. Whether you want a cute wooden hedgehog house or a more naturalistic twig igloo, you'll be sure to find the perfect fit for your garden.

How do you attract hedgehogs into hedgehog houses?

'Place the house near plenty of nesting material – the hedgehog will want to build her own nest, so site the box next to lots of leaves, straw, hay, grasses or fine twigs – the more unkempt the better' says Sally Coulthard in her book The Hedgehog Handbook.

Don't clear or cut back the plants around the hedgehog house – you need them to feel as protected as possible. 'Leave it in a quiet corner of the garden, and it will house successive hedgehogs – who might stay for just one night or hunker down for weeks over winter.'

Other ways to attract hedgehogs to your garden – and keep them there – is to stop using chemicals, to be careful when you are strimming or clearing parts of the garden, to ensure your pond has a safe exit for them and that any netting is well clear of where hedgehogs might room. Finally, put out food (at first) and water for them – but not in the hedgehog house – hedgehogs don't eat where they nest, so put it near the house but not inside.

How do you attract hedgehogs but not rats?

You can encourage hedgehogs into the garden by creating a hedgehog-highway. 

'Make holes in your fences so that they can travel between gardens,' says gardener Kate Bradbury. 'It is thought that they can travel up to a mile a night in search of food so one garden is never enough for them.'

'Don't be too tidy,' advises Monty Don in a recent entry in his blog. 'Try not to disturb natural hibernation spots, especially if you are vigorously tidying up after a long winter. These creatures all make a slow start and will be lethargic and weak – be mindful of them.'

To ensure you're not attracting rats, put the hedgehog's food in an open area next to the hedgehog house so that the hedgehog can get to it first – rats tend to run along boundaries and are rarely brave enough to dart out into open areas. 

Hedgehogs are mostly nocturnal, so put the food out just before you go to bed – that gives them a better chance of getting to it first. Finally, only put a little food out at a time – they like cat food, although ideally you want them to eat your garden's pests. More on this below.

What do hedgehogs eat?

Never leave milk out for hedgehogs as they are lactose intolerant, instead cat or dog food (tinned or kibble) is a popular supermarket option that will definitely go down well with visiting hedgehogs. Be sure to use a heavy bowl or a terracotta saucer as hedgehogs have poor eye-sight and are prone to knocking things over. 

As well as slugs and snails, hedgehogs love earthworms. Encouraging earthworms into your garden not only provides your hedgehogs (and any visiting birds) with a tasty meal but 'they're also important for the health of your soil,' says Sally Coulthard in her book The Hedgehog Handbook.

'Encourage earthworms to flourish by spreading rotting organic materials such as compost, dried leaves or manure along your beds'

Do I need to clean out my hedgehog house?

You need to clean out your hedgehog house once a year towards the middle to end of spring to prevent pests taking advantage of the cozy box. However, make sure that you don't still have a hedgehog inside before you start clearing out.

Other than that, a hedgehog house is a very low maintenance addition to the garden but one that can make a world of difference to wildlife.
