How Long Do Spiders Live? Lifespan Guide.

There are over 35,000 species of spiders but how long do spiders live? Although scientists are still trying to determine the lifespan of each, there is a general consensus that most spiders live for around two years. Some may live up to five years or even more, however, the average lifespan for a spider is two years.

What is the average life cycle of a spider?

All spiders have a similar life cycle, from the humble house spider to the tarantula. They begin as eggs, develop into spiderlings, and eventually mature into fully grown adults. Let’s take a closer look at each of these stages in their lives right now.


Female spiders can fertilize their eggs at will, but they often store sperm from a previous mating to use later.

Spider eggs hatch within two weeks of being laid, and the baby spiders remain in the eggs until it is warmer and the weather is better.

Some species of spiders, such as the Wolf spider, can release their eggs from their egg sacs at will. This means that they can control when the eggs hatch and how many young spiders are born.

Young Spiders, or Spiderlings

Spiderlings are the young of a spider. They hatch from eggs and tend to run away when they first emerge. This is because they are vulnerable at this stage and have not yet developed their defenses.

How long do spiders live?

They are typically very small and have not yet developed their adult features. Spiderlings live off their egg sac for a few weeks before they start to spin webs and hunt for food.

During this time, they grow rapidly and develop their hunting and web-spinning skills.

Spiderlings can release their eggs at will, but they usually do not do so until they have grown a bit larger.

Adult Spiders

There are three classifications for adult spiders: juvenile, subadult, and adult. Juvenile spiders are those that have not yet reached their final stage of development.

Subadult spiders are those that have reached their final stage of development but have not yet reproduced.

Adult spiders are classified according to when they reach their final stage of development: either immediately after they reproduce or after they’ve molted a number of times.

Interestingly, female spiders that have not used sperm from a previous mating may lose it through molting. The lifespan of spiders can depend on a variety of factors, including the species and gender.

Male spiders typically live for less time than female spiders, as they often cannibalize each other during mating.

When a female spider is ready to lay her eggs, she will find a safe spot and spin a web. She will then deposit her eggs in the center of the web and cover them with a layer of silk.

Male spiders are usually nearby when this happens, and they often help to take care of the eggs.

How long do spiders live?

Spiders can survive for up to a year, depending on the species. While there are some spiders that have a lifespan of only a few months, others can live up to a year or more.

Interestingly, spider populations decline when they are killed by sprays or when there is no food available. Conversely, spiders tend to thrive in moist and humid environments with plenty of prey.

On the other hand, spiders are an important part of the ecosystem as they help reduce insect populations. By catching and eating insects, spiders play a vital role in keeping the environment healthy.

How long can a spider live without food?

Spiders can survive for a really long time without food. Depending on the type of spider and the conditions it lives in, it can survive anywhere from a few months to over a year without eating.

The average lifespan of a house spider can range from around three months to up to 2 years, depending on the size and species of spider.

However, there are some factors that can influence how long a spider can live. Generally speaking, larger spiders can survive longer than smaller spiders, and pet spiders can last longer than wild spiders.

How long do spiders live in captivity?

Spiders in captivity tend to have a longer lifespan than those who live in the wild. House spiders usually live for one to two years, while spiders in other environments can live up to six years.

On the other hand, if you are able to provide a spider with an undisturbed and safe place to live, it can increase its lifespan in captivity by reducing predation or intraspecific competition.

How long can a house spider live without water?

House spiders can live without water for a relatively long time. On average, they can survive 3-4 months without it. However, there are certain factors that may affect this estimate, such as the temperature and humidity of their environment.

While, on average, adult spiders can live for weeks without water, spiderlings are much more susceptible to dehydration and are likely to die within a few days.

How long do wild spiders live?

Spiders are found on every continent except in Antarctica. They can be found in a variety of habitats, including forests, fields, deserts, and wetlands. While there is no definitive answer to how long spiders live in the wild, they typically have a lifespan of 1-2 years.

Out of the tens of thousands of spider species, most only live for a year. However, some spiders have a lifespan that can exceed ten years. So, how long do wild spiders live? It depends on the species, but most only live for a year.

Although the lifespan of spiders in the wild is not as well documented as that of domesticated spiders, it is known that tarantulas can live for up to 30 years. Male spiders usually have a shorter lifespan than females, and some species of spiders do not survive past their first molt.

Interestingly, female spiders outlive their male counterparts by living up to 25 years on average. This is due to the fact that they take more time to mature and require more food.

Male spiders, on the other hand, die soon after mating because they consume their entire reproductive system during the process.

How Long Can a House Spider Live Underwater?

Spiders have a variety of different methods of surviving in different environments. Some spiders, like the diving bell spider, can live underwater for a few minutes by trapping air bubbles under their webs. They will then rise to the surface to breathe.

Interestingly, some spiders have evolved to adopt a coma-like condition which allows them to remain underwater for long periods of time. This enables the spiders to travel greater distances and find new areas to live in.

This means that spiders that live above water can actively immerse themselves in order to capture prey. They will spin a web at the surface of the water and wait for insects to fly or land on it before pouncing on them.

How long do garden spiders live?

Garden spiders are not harmful to human beings and can eat insects that may be considered pests. Garden spiders typically have a lifespan of one to two years.

In general, garden spiders have a lifespan of one year. However, the female can die after mating in cold weather conditions.

Interestingly enough, the young ones are less than 1 in (2.5 cm) long and manage to live among humans without us noticing them.

How long do black widow spiders live?

Black widow spiders can be very easily identified by their shiny black body and the red hourglass shape on their abdomen.

These spiders are infamous for their venomous bite, but the majority of bites do not result in death. In fact, most people who are bitten by black widows experience only minor symptoms.

On the other hand, black widow spiders are not typically aggressive, and they can live near humans without any conflict. In fact, they often occupy dark and secluded spaces that coincide with human dwellings.

Consequently, it is not common for people to come into contact with these spiders unless they are looking for them.

The lifespan of a black widow spider varies depending on the species, but it must live for around one to two years.

How long do barn funnel weaver spiders live?

The Barn Funnel Weaver is a common spider species found in and around human homes. They are typically brown or black in color with a white stripe on their abdomen. These spiders live for about one year, but some have been known to live up to two years.

Though they are small, barn funnel weaver spiders can be found in many places. These spiders are relatively harmless and can go unnoticed by humans for a long time.

These spiders build funnel-shaped webs to trap prey, which they often eat alive. Although they have a short lifespan – around one year – they can produce up to eight egg sacs during their lifetime, each containing about 100 eggs.

How long do wolf spiders live?

The lifespan of a wolf spider can vary depending on its location. For example, in colder climates, they may only live for 2-3 years, while in warmer climates, they may live for 5-7 years.

In general, male spiders die earlier than female spiders. This is due to the fact that males expend a great amount of energy in search of a mate.

Once they find a mate, they die shortly after. Female spiders, on the other hand, often lay eggs and continue to live for an extended period of time.

Having said that, there is a great deal of mystery surrounding their lifespan. Some experts believe that they may only live for a year or two, while others think that they may be able to live for up to 10 years.


Spiders can live for a long time if they are not killed by predators or other means. There are some ways to get rid of spiders without harming them, but sometimes professional help is necessary.


How big can house spiders get?

The size of the big house spider is its most distinguishing feature. Adult males may have a leg spread of up to 4 inches, while females can have a leg span of up to 2 inches. The big house spider is usually dark orange, brown, or beige in color.

How long do wild spiders live?

Some spiders live for a year or less, while others might survive for up to twenty years. Spiders, on the other hand, suffer several threats that diminish their chances of living to a ripe old age. Many animals eat spiders, their eggs, and their young.
