There are so many types of earthworm are available, their lifespan is different according to their habit, here we have mentioned most common earthworm that found at your nearby places.
Again there is one question pop up in your mind, but how long do earthworm live? Do not worry, here we have covered all information that will help you to better understand this tiny creatures
How Long does an Earthworm Live?
Earthworms, belonging to the phylum Annelida, are segmented worms that reside in soil and leaf litter across the globe. Earthworms have an average lifespan ranging from 1 to 8 years, depending on various factors such as species, environment, and human intervention.
To gain a deeper understanding of the lifespan of earthworms, let’s take a closer look at some common species and their respective lifespans:
- Lumbricus terrestris (Common Earthworm)
- Lifespan: 4-8 years
- Description: The Lumbricus terrestris, also known as the nightcrawler or dew worm, is one of the largest and most commonly found earthworm species. These worms are usually reddish-brown and can grow up to 14 inches in length.
- Eisenia fetida (Red Wiggler)
- Lifespan: 1-2 years
- Description: The Eisenia fetida, commonly referred to as the red wiggler or manure worm, is a smaller earthworm species. They have a reddish-brown color with a distinctive banding pattern. These worms are frequently used in vermicomposting due to their voracious appetite for organic matter.
- Aporrectodea caliginosa (Grey Worm)
- Lifespan: 2-3 years
- Description: The Aporrectodea caliginosa, also known as the grey worm or brandling worm, is a medium-sized earthworm species that is widespread in many parts of the world. They have a greyish coloration and can reach lengths of about 3 inches.
While these examples provide a general idea of earthworm lifespans, it’s important to note that factors such as habitat conditions, temperature, moisture levels, and the presence of predators can significantly influence an individual worm’s longevity.

How long do earthworms live in a container?
Earthworm lifespan within a container can vary based on several factors. On average, earthworms can live for around 1 to 2 years in a controlled container environment. However, their lifespan depends on key factors like the type of container, soil conditions, moisture levels, and overall care.
Providing an optimal environment is essential for earthworm longevity. Ensure a well-draining container with suitable bedding material, like compost or peat moss, to mimic their natural habitat. Maintain consistent moisture levels, as overly wet or dry conditions can affect their survival. Regularly adding organic matter, such as kitchen scraps, helps sustain their diet.
How long do earthworms live in captivity?
In captivity, earthworms can live for several years if provided with the right conditions. The lifespan can vary depending on the species, but commonly kept earthworms can live for 2 to 5 years or even longer with proper care.
How long do earthworms live without food?
Earthworms can survive for a few weeks to a couple of months without food, depending on their energy reserves. However, it is essential to provide earthworms with a consistent food source to maintain their health and longevity.
Do earthworms survive after being cut in half?
The common belief that earthworms survive being cut in half is a bit of a myth. While it’s true that earthworms can regenerate some body parts, cutting them in half can be harmful and often fatal to them.
When an earthworm is cut in half, the front part (the “head” end) may have a chance of regenerating a new tail, and the back part (the “tail” end) may have a chance of regenerating a new head. However, this process is not foolproof, and it largely depends on the specific species of earthworm and the extent of the damage.
In many cases, cutting an earthworm in half can lead to severe injury or death. Earthworms have vital organs and systems distributed throughout their bodies, and cutting them disrupts these systems, making it difficult for them to survive. Furthermore, the regenerative process is slow and energy-intensive, and the worm may succumb to stress, infection, or other complications.
How many days do earthworms live?
Earthworms have different lifespans depending on the species and environmental factors. On average, most earthworms live for 1 to 8 years in their natural habitats.
Factors Influencing Earthworm Lifespan
Here are some factors that affect lifespan of earthworm.
Earthworms thrive in specific environmental conditions, including optimal soil moisture, aeration, and temperature. Excessive dryness or moisture can be detrimental to their survival. Additionally, extreme temperatures outside their tolerance range can have adverse effects on their lifespan.
Predatory creatures such as birds, frogs, snakes, and certain insects pose a constant threat to earthworms. These predators can significantly reduce their lifespan through predation, limiting their opportunity for reproduction and natural life cycle completion.
The quality of the soil in which earthworms reside plays a crucial role in their lifespan. Healthy soils rich in organic matter provide ample food sources for earthworms, allowing them to thrive and live longer. Conversely, polluted or contaminated soils can have detrimental effects on their health and survival.
Human activities such as habitat destruction, excessive pesticide use, and soil compaction can disrupt earthworm populations and shorten their lifespan. Preserving natural habitats, implementing sustainable agricultural practices, and reducing the use of harmful chemicals can contribute to the longevity of earthworms.
Earthworms may not receive the same level of attention as other charismatic animals, but their role in maintaining soil health and ecosystem balance cannot be understated. These fascinating creatures have an average lifespan ranging from 1 to 8 years, with some species living even longer. Factors such as environmental conditions, the presence of predators, soil quality, and human intervention greatly influence their longevity.
By understanding how long do earthworm live and the factors that affect it, we can appreciate their significance and work towards creating a more favorable environment for their survival. Let us recognize and celebrate the unsung heroes beneath our feet, the earthworms that silently contribute to the health and harmony of our planet.
