How long Can Spiders Live Without Food? (Shocking Fact of Spider)

By delving into their fascinating world, please find out how long can spiders live without food. Learn how they’ve adapted in such incredible ways, biologically and behaviorally.

Spiders and their world are fascinating. Spiders have captivated humanity for thousands of years due to their intricate webs, unique hunting strategies, and wide geographical distribution. One of the most intriguing questions about spiders is how long they can survive without food. The biology of spiders, how they adapt to their environments, and other related topics are explored in greater depth here.

Understanding of Spider Anatomy and Nutrition

How long Can Spiders Live Without Food?

Spiders’ survival time without food requires knowledge of spider biology and the foods they typically consume. Most spider species are carnivores that feast on other insects and even smaller spiders. An animal’s diet can be influenced by its size, species, and environment. Some spiders feed rather frequently, while others may go days or weeks without meals.

How Long Can Spiders Live Without Food? The Facts

Spider Species Approximate Survival Time Without Food
House Spider (Tegenaria domestica) 4-8 weeks
Wolf Spider (Lycosidae family) 2-4 weeks
Jumping Spider (Salticidae family) 10-14 days
Black Widow (Latrodectus spp.) 2-3 months
Tarantula (Theraphosidae family) Up to 6 months
Orb-Weaver Spider (Araneidae family) 3-4 weeks
Daddy Long-Legs Spider (Pholcidae family) 4-5 weeks
Brown Recluse (Loxosceles reclusa) 4-6 months

The Probability of Starvation Survival for a Spider

Spider species have different limits on how long they can go without eating. When it comes to starvation, some animals are better equipped than others. More giant spiders have a greater fat reserve, so Tarantulas may go longer between meals than smaller spider species.

A spider’s metabolic rate slows down in colder temperatures, allowing it to go longer between meals. In the winter, spiders hibernate and can survive for extended periods without eating.

Spiderlings have a greater appetite than adult spiders since they are still growing. More enormous adult spiders store more energy for lean times when food is limited.

While the topic of how long a spider can survive without food is the primary emphasis of this article, it is equally crucial to highlight that water is necessary for their survival. Even though a spider can go weeks without eating, it may still need water to be alive.

The Impact of Hunger on a Spider’s Behavior

Spiders’ behavior changes drastically when they’re hungry. Spiders become more hostile and go off in quest of food when hungry. During certain times of the year, when food sources are scarcer outside, you may find that more spiders than usual have found their way into your home.

Spiders: a Variety of Species, Each with Its Methods of Survival

To fully grasp the nuanced question of how long can spiders live without food, examining the wide variety of arachnids is necessary. Given the range of habitats in which spiders may be found, their survival methods, particularly their fasting times, would also vary. From the common garden variety to the more exotic tarantula, spiders exhibit a wide range of qualities traits that allow them to thrive in their habitats.

Changes in Metabolism and Stamina

Spiders rely heavily on their metabolic adaptations to keep them alive when food is scarce. Most spiders exhibit some form of metabolic rate control according to their physiological needs and environmental difficulties. When there is no sign of prey nearby, the arachnid carefully depletes its energy stores, demonstrating its remarkable skill for resource management.

Species exhibit a wide range of metabolic strategies. For example, Spiders living in the desert are often exposed to highly harsh settings where food is scarce, at best. These spiders have adapted metabolic systems that enable them to retain more fat, ensuring a stable energy source even during extended periods between meals. Having to figure out what to eat daily is an ongoing difficulty. Therefore, these adjustments are crucial for survival.

Mutual Support and Interdependence

To improve their chances of survival, spiders will sometimes create symbiotic associations with other organisms. Mutualistic relationships between insects and peacock spiders, in which the former provides defense in exchange for food, have been seen. Forming and maintaining such relationships is crucial to the spider’s ability to survive without food, as they provide an alternate source of sustenance in times of need.

Malnutrition and Having Children

One understudied component of resource management in spiders is their reproductive habits and the potential impact of food scarcity on them. After mating, female spiders often prioritize egg production over all else, so they may consume their mate if necessary. The fact that female spiders lay fewer eggs when food is low demonstrates how severely a food shortage might threaten the survival of an entire species.

Migration Caused by the Need for Food

How long Can Spiders Live Without Food?

The primary issue is migration for food, and the secondary problem is how long spiders can endure without food. Some kinds of spiders migrate great distances in search of more suitable feeding grounds when they find that their current environment does not provide enough food. When food is scarce, spiders sometimes utilize a strategy known as “ballooning,” in which they release strands of silk carried by the wind to a new location. This conduct reveals a clever survival strategy and an intriguing aspect of their ecological behavior.

Human Influence on Spiders and Their Future

Humans have an indirect effect on the problem of spiders going hungry. Pesticides, habitat destruction, and a changing climate are just a few ways humans impact spider populations and the availability of their food. Despite their incredible resilience, spiders should not be under undue stress, which is why conservation efforts and ecological awareness are so important.


In a typical day, how many times do spiders eat?

Many species of spiders only eat once every few days, though this might vary widely. However, some larger animals can go without food for weeks.

Is it true that spiders eat other spiders?

Some spiders can cannibalize each other when food is scarce.

Can spiders survive without water?

Absolutely. Since spiders need water for survival, dehydration is often a more significant threat than starvation.

How do spiders keep going when there’s nothing to eat?

Spiders can adapt to their surroundings by slowing their metabolism, increasing their resting time, and storing energy.


The question of how long can spiders live without food? provides a fascinating insight into these creatures’ remarkable resilience and adaptability. Their evolutionary adaption, demonstrated by their ability to go without food for long stretches, is undeniable. However, like other forms of life, spiders have their own constraints.

Although they may fast for long periods, they must eat to maintain life and reproduce. The next time you stumble across one of these eight-legged wonders, consider the complicated interplay between biology, environment, and survival tactics.
