Quick Answer

Slow worms primarily eat small invertebrates like slugs, worms, and insects. Providing a habitat with plenty of these food sources will help attract them to your garden.

Understanding Slow Worms

Slow worms, often mistaken for snakes, are actually legless lizards. They're quite harmless and can be a boon to your garden by controlling pests naturally. In the UK, especially in areas like Staffordshire, they thrive in gardens that provide suitable shelter and food.

What Do Slow Worms Eat?

Slow worms mostly feed on small invertebrates. Their diet includes:

  • Slugs, which they help keep in check
  • Earthworms that inhabit moist soil
  • Beetles and other small insects

In essence, slow worms play a crucial role in maintaining the ecological balance in gardens by reducing pest populations.

Creating a Slow Worm-Friendly Garden

Providing Shelter

To encourage slow worms, it's essential to offer them suitable habitats. They prefer areas that are undisturbed and have plenty of cover. Consider:

  • Leaving a compost heap or leaf pile, which provides warmth and attracts their prey
  • Creating log piles or rockeries where they can hide and hunt
  • Maintaining some long grass areas for shelter

Encouraging Invertebrates

To ensure a steady food supply, your garden should support a healthy population of invertebrates. Here’s how you can promote this:

  • Use organic gardening methods to avoid harmful pesticides
  • Maintain moist soil conditions by mulching and watering appropriately
  • Plant native wildflowers to attract a variety of insects

Timing and Seasonal Considerations

Slow worms are most active during the warmer months, typically from March to October in the Midlands. During the colder months, they hibernate, so it's crucial to ensure they have safe, undisturbed spaces.

Month Activity Garden Tips
March-April Emerging from hibernation Ensure habitats are ready and undisturbed
May-September Active and feeding Monitor invertebrate levels and maintain habitats
October Preparing for hibernation Leave leaf piles for shelter
