One common question prospective tarantula keepers ask is, “How long do pet tarantulas live?” In this comprehensive guide, we will explore the lifespan of pet tarantulas, the factors that influence their longevity, tips for ensuring their well-being, and much more.

Understanding Tarantulas as Pets

Before delving into the lifespan of pet tarantulas, it’s essential to understand some key aspects of keeping them as pets:

  • Variety of Species: Tarantulas come in various species, each with unique characteristics and care requirements. Some popular pet species include the Chilean Rose Hair Tarantula, Mexican Red Knee Tarantula, and Brazilian Black Tarantula.
  • Solitary Nature: Tarantulas are solitary creatures who prefer to live alone and can become stressed or aggressive when housed with others.
  • Low Maintenance: Compared to many other pets, tarantulas are relatively low maintenance. They don’t require much social interaction and have straightforward feeding and habitat needs.
  • Venomous but Mild: While tarantulas are venomous, most species kept as pets have mild venom that is not dangerous to humans. Their primary use of venom is for subduing prey.

The Lifespan of Pet Tarantulas

The lifespan of a pet tarantula can vary significantly depending on several factors, including the tarantula’s species, gender, care, and environment. Here is a general overview of the expected lifespans of pet tarantulas:

  • Male Tarantulas: Male tarantulas typically have shorter lifespans than females. On average, they may live for about 2 to 5 years. After reaching maturity, which can take a few years, male tarantulas often die shortly after mating.
  • Female Tarantulas: Female tarantulas tend to have longer lifespans, with some living for several decades in captivity. The lifespan of a female tarantula can range from 10 to 30 years or more, depending on the species.
  • Species Variation: The species of tarantula you choose affects its lifespan. Some species are known for their longevity, while others have shorter lifespans.
  • Environmental Conditions: Proper care and environmental conditions, such as temperature, humidity, and habitat size, can influence a tarantula’s overall health and lifespan.
  • Diet and Nutrition: Providing a well-balanced diet and ensuring your tarantula receives proper nutrition can contribute to a longer and healthier life.

Factors Influencing Tarantula Lifespan

Several factors can influence the lifespan of pet tarantulas:

  • Species: As mentioned earlier, different tarantula species have varying lifespans. Research the specific species you plan to keep to understand its expected lifespan.
  • Gender: Gender plays a role in lifespan, with females generally living longer than males.
  • Habitat and Enclosure: Maintaining an appropriate habitat with the right size, substrate, temperature, and humidity levels is crucial for a tarantula’s well-being and longevity.
  • Diet: Providing a varied diet of live prey, such as crickets, mealworms, and roaches, ensures your tarantula receives essential nutrients.
  • Handling: Tarantulas are best left undisturbed as they can become stressed when handled. Excessive handling can lead to health issues and a shorter lifespan.
  • Molting: Tarantulas molt to grow and regenerate. Proper care during molting is critical to prevent injuries that can shorten their lifespan.

Tips for Ensuring a Long and Healthy Life for Your Pet Tarantula

To help ensure a long and healthy life for your pet tarantula, consider the following tips:

  • Research Care Requirements: Thoroughly research the specific care requirements of your tarantula species, including temperature, humidity, and diet.
  • Provide Adequate Space: Ensure your tarantula has a spacious and appropriately sized enclosure with a suitable substrate.
  • Monitor Environmental Conditions: Regularly check and maintain the temperature and humidity levels within the enclosure to mimic the tarantula’s natural habitat.
  • Avoid Overfeeding: Overfeeding can lead to obesity and health issues. Follow a feeding schedule appropriate for your tarantula’s age and size.
  • Provide Fresh Water: Always have a small dish of clean water for your tarantula. Some species may drink occasionally.
  • Handle with Care: Minimize handling and disturbances. When handling is necessary, do so gently and with clean, dry hands to avoid causing stress or injury.
  • Observe Molting: Be attentive during the molting process. Offer a softer substrate to support your tarantula during this vulnerable period.


Are tarantulas dangerous to keep as pets?

Most tarantula species kept as pets have mild venom and are not dangerous to humans. However, handling should be done with care to prevent bites.

How can I determine the gender of my tarantula?

Determining the gender of a tarantula requires examining the underside of the abdomen, where males have modified structures called tibial spurs.

Can I keep multiple tarantulas in the same enclosure?

Tarantulas are solitary animals and should generally be kept individually. Attempting to house multiple tarantulas together can lead to aggression and injury.


The lifespan of a pet tarantula varies depending on species, gender, care, and environmental factors. By providing the appropriate habitat, nutrition, and care, you can significantly increase the chances of your tarantula enjoying a long and healthy life as a captivating and low-maintenance exotic pet. Always research the specific requirements of your tarantula species to ensure its well-being and longevity.
