Slow worm

There’s nothing quite like the excitement of finding a new creature in your garden and if you find a slow worm, you should consider yourself quite lucky indeed. In the UK, slow worms are becoming rarer, and a vast amount of people have never even seen one.

If you are lucky enough to see one, it is probably best to just leave it alone as although they resemble snakes, they are quite harmless to humans and are probably doing you a favour in keeping the slug population down.

If, however, you need to get rid of them for some reason, maybe you are worried the local cats will get them or maybe you are afraid or simply don’t like them, read on to find out how to get rid of them safely and humanely.

What is a Slow Worm?

A slow worm is a type of legless lizard that is found in Europe and parts of Asia. They are so named because of their slow, steady movement. They typically grow to between 10 and 12 inches in length, though some specimens have been known to reach lengths of up to 20 inches.

Slow worms are mostly active at night, and during the day they can be found hiding under rocks or in burrows. They feed on slugs, earthworms, and other small invertebrates.

Under the Wildlife and Countryside Act of 1981, these reptiles are protected in the UK and harming a slow worm is a criminal offence.

Are Slow Worms Dangerous?

No, slow worms are not dangerous. They are harmless to humans and pets, although, like any wild lizard, they can bite when threatened.

Although they have a snake-like appearance, slow worms are actually part of the lizard family and while they’re not poisonous or venomous, their bites can be painful if they manage to get hold of your skin.

Like many other lizard species, the slow worm also has the ability to drop its tail and regrow a new one. Slow worms dropping their tails is a defence mechanism.

The dropped tail will continue to wiggle for a while, which makes it look like easy prey, therefore, giving the slow worm time to escape.

How to Get Rid of Slow Worms?

If anything at all, we advise that slow worms are just left alone to get on with keeping your garden clear of slugs.

However, if you must get rid of them for whatever reason, you will need to relocate them as they are protected by law and cannot be intentionally harmed.

Note: Slow worms are social creatures so where there is 1, there is likely to be more.

What You Need

  • Shovel
  • Large Box or Crate
  • Net
  • Gloves

Step 1 – Enlist Some Help

Enlisting someone to help you will make your life a lot easier, particularly if you are afraid of the slow worms.

Another pair of hands is always helpful when trying to catch these little critters. Your helper may also be able to help you with finding a suitable location.

Step 2 – Find the Slow Worms a New Home

You may think that choosing a location for the slow worms’ new home is a tricky task, but it is quite simple as long as you think about a few things including where they are living now.

  • Move slow worms at least 2 miles away
  • Ensure you move them to a low-traffic area away from footfall and roads
  • Slow worms will hide in leaf litter, log piles, compost heaps etc.
  • Slow worms hibernate between October and March
  • Slow worms are quite reclusive although they occasionally like to bask in the sun

Note: A friend or relative may be happy to move the slow worms to their own garden.

Step 3 – Catch the Slow Worms

Although they are named slow worms, they can move quite quickly but they are still easy to catch. If they are out in the open, it is probably best not to handle them if possible and instead use a large butterfly net (amazon link – opens in a new tab).

If, however you unearth them from their burrow, you could try and carefully lift the compost heap or log pile where they are and relocate the whole thing or at least a good portion of it.

If you have unearthed one or 2 during the winter months, they will be in hibernation so you can just cover them back up and lift the area where they are without disturbing them.

Note: If you must handle them, we recommend wearing gloves in case they attempt to bite you out of fear.

Step 4 – Releasing them

If you are releasing the slow worms out into the wild, think about the area and the habitat that they will inhabit. Consider the things noted above.

If you are creating a new home for them with a friend or family member, there are a few things you can do to make the area more hospitable.

You should set aside a quiet corner in your garden for slow worms. You can make this corner by piling logs, pruning, leaves, and sticks. When plant matter rots down, it will attract bugs and insects that the slow worms can feed upon.

Alternatively, you can create a compost pile as this makes an ideal home for slow worms. If you already have a compost heap in mind, that’s great.

Note: It would be best to not use pesticides when you have slow worms because pesticides can deprive your garden of slow worm prey.

Can You Keep Slow Worms as Pets?

Although they are protected, legally, slow worms can be caught and kept as pets although you really wouldn’t want to have one, they are best left outside.

Slow worms will burrow underground and hibernate for 6 months of the year and even when they are active, they are burrowing animals which means that they will spend a great deal of time hidden, and you will almost never see them.

A slow worm diet is made up of regular slugs and bugs from your garden in the UK which are not readily available in commercial pet shops. Feeding slow worms anything but their natural diet would not be beneficial to them as their gut flora and fauna may struggle to adapt.

Finally, slow worms do not like to be handled and in fear, they may bite or pinch or even drop their tail – not to mention, when scared they actually poo too!

Conclusion

A slow worm is a sleek, shiny, and small reptile with a legless body similar to a snake. They love to inhabit rotting wood, compost, meadows, gardens, and grasslands. As slow worms are small reptiles, they become a quick snack for many predators.

If humans encounter them in the wild, leaving them alone is the best option but if you have them in your garden and you want to get rid of them, you will need to relocate them as they are a protected species under the Wildlife and Countryside Act of 1981.
