The most distinctive feature of the Common Hedgehog is its coat of spines. When threatened, the hedgehog can roll up into a ball, with spines sticking out in all directions. Hedgehogs are nocturnal animals, living in undergrowth, hedgerows and gardens. They eat slugs, snails, insects and even mice. When winter arrives, it will make a pile of dead leaves and go to sleep. At first they may wake up occasionally, but will then settle into hibernation until the next spring.
Don't use pesticides or slug pellets in your garden or you will kill off species which are links in the food chain. Slug pellets can kill Hedgehogs. If you are overrun with slugs and your resident Hedgehog(s) do not seem to be keeping the numbers down you could try beer traps (dishes of beer placed at the bottom of plants into which the slugs fall or climb). You can also encourage hedgehogs by putting out food and water throughout the year, but not bread or milk, which upset its stomach.
