Are Snails Nocturnal?

Snails are fascinating creatures that have captured the curiosity of humans for centuries. They are commonly seen during the day, slowly gliding along surfaces, but their true activity seems to happen under the cloak of darkness.

This raises the question: Are snails nocturnal?

Are Snails Nocturnal?

Yes, snails are indeed nocturnal creatures. Being nocturnal means they are most active and alert during the nighttime hours. However, it’s essential to note that snails may still come out during the day, though they prefer the cover of darkness.

Are Garden Snails Nocturnal?

The majority of land snail species, including the common garden snail, exhibit nocturnal behavior. Garden snails are not only the most widespread type of snails but also notorious pests that can cause damage to your precious plants.

As these snails are active at night, it’s crucial to safeguard your plants before going to bed to prevent them from becoming a late-night feast.

Do Snails Come Out During the Day?

Although snails are predominantly nocturnal, there are instances when they venture out during the day. They might do so under certain circumstances, such as being forced out or in response to rainy weather when the ground is moist.

However, snails don’t particularly like sunlight and will try to avoid coming out during daylight hours whenever possible. Some snails have developed a unique defense mechanism – they coat their shells with a special mucus epiphragm to protect themselves from sunlight.

This mucus acts as a shield, helping to retain moisture within the snail’s body and guarding against potential attacks from other invertebrates.

Are Snails More Active at Night?

Snails are undoubtedly more active at night than during the day, hence their classification as nocturnal creatures. They tend to be most active during the early morning hours when the air holds more moisture.

Where Do Snails Sleep?

Snails retreat into their shells when they rest, and some species even go into a hibernation-like state during the winter months. During this resting period, they also utilize the mucus epiphragm to protect themselves.

Interestingly, not all snail species hibernate or enter a state of inactivity. After their hibernation period, they emerge in the spring, often hungry and ready to eat.

When it comes to sleeping arrangements, snails don’t build nests. Instead, they seek out suitable locations within their environment. Most land snails, including garden snails, often find cozy spots on the leaves of plants to rest.

Moreover, snails can sleep upside down, with their bodies retracted into their shells and their shells facing the ground.

How to Protect Plants Overnight

Considering snails’ nocturnal activity, the time you spend asleep is when they’re most likely to feast on your plants. Fortunately, there are effective ways to safeguard your plants during the night:

Encourage Natural Predators

One of the best methods to control snail populations is to encourage natural predators in your garden. Hedgehogs are an excellent example of snail predators that won’t become pests themselves but will help keep the snail population in check.

Setting up suitable shelters for hedgehogs will not only benefit these nocturnal creatures but also ensure they help protect your plants by consuming snails.

Use Difficult Terrains

Snails struggle to traverse certain types of terrains, which can be uncomfortable and harmful for them. If your garden doesn’t entirely consist of grass, you can surround its borders with substances that deter snails.

Gravel is an effective terrain that discourages snails from crossing. The cold and uncomfortable surface, along with the sharp edges, makes it unattractive for snails. By surrounding your grass with gravel, you’ll prevent snails and slugs from entering the area.


In conclusion, snails are primarily nocturnal creatures, although they might come out during the day under specific circumstances. They sleep upside down, hiding on the undersides of leaves and rocks, and some species even hibernate during the winter months.

To protect your plants from snail damage overnight, consider attracting natural nocturnal predators like hedgehogs to your garden and use terrain deterrents like gravel.
