How Often Does a Tarantula Molt? A Guide to Understanding Your Pet Tarantula’s Molting Cycle


As a tarantula owner, it is important to understand the molting process of your pet. Molting is a natural process that every tarantula goes through in order to grow. During this process, the tarantula sheds its old exoskeleton and grows a new one. But how often does a tarantula molt?

The frequency of molting varies depending on the species of tarantula and its age. Younger tarantulas tend to molt more frequently than older ones, with some molting as often as every few months. However, as a tarantula grows older, the frequency of molting decreases, with some species only molting once a year or less.

Key Takeaways

  • The frequency of molting in tarantulas varies depending on the species and age of the tarantula.
  • Younger tarantulas tend to molt more frequently than older ones.
  • As a tarantula grows older, the frequency of molting decreases.

Understanding Tarantula Molting

As a tarantula owner, it is important to understand the molting process of your pet spider. Molting is a natural process that all tarantulas go through in order to grow. In this section, I will discuss why tarantulas molt and the molting cycle.

Why Do Tarantulas Molt?

Tarantulas molt in order to grow. As tarantulas grow, their exoskeleton becomes too tight and they need to shed it in order to continue growing. During the molting process, the tarantula will shed its old exoskeleton and replace it with a new, softer, and bigger one.

The Molting Cycle

The molting cycle of a tarantula can vary depending on the species, age, and environmental factors. Generally, tarantulas will molt about once every six months, and sometimes only once per year. Before a molt, tarantulas will usually stop eating and become very slow and sluggish. They may also develop a bald spot on their abdomen that grows increasingly darker as the molt approaches.

During the molting process, the tarantula will lay on its back and start to crack the old exoskeleton. This can take up to a few hours, and the tarantula is extremely vulnerable during this time. It is important to leave the tarantula alone during the molting process and not disturb it.

After the molt, the tarantula will be very soft and vulnerable. It is important to wait a few days before handling the tarantula again and to make sure it has access to water and food.

Factors Influencing Molting Frequency

As a tarantula owner, you might be wondering how often your spider will molt. The frequency of molting depends on several factors, including environmental and biological factors. In this section, I will discuss the factors that influence molting frequency.

Environmental Factors

The environment in which your tarantula lives plays a significant role in its molting frequency. Here are some environmental factors that can influence how often your tarantula will molt:

  • Humidity: Tarantulas need a certain level of humidity to molt successfully. If the humidity is too low, it can cause the molting process to fail, and your tarantula may die. On the other hand, if the humidity is too high, it can cause mold growth in the enclosure. The ideal humidity level for most tarantulas is between 60% and 80%.
  • Temperature: Temperature also plays a role in the molting frequency of tarantulas. If the temperature is too low, it can slow down the molting process, while high temperatures can speed up the process. The ideal temperature range for most tarantulas is between 75°F and 85°F.

Biological Factors

Apart from the environmental factors, several biological factors can influence the molting frequency of tarantulas. Here are some of them:

  • Age: The age of your tarantula is one of the most significant factors that influence its molting frequency. Younger tarantulas molt more frequently than older ones. For instance, a juvenile tarantula may molt every few weeks, while an adult may only molt once or twice a year.
  • Hormones: Hormones also play a role in the molting frequency of tarantulas. Female tarantulas tend to molt more frequently than males, especially during the breeding season.
  • Species: Different tarantula species have different molting frequencies. Some species molt more frequently than others, depending on their growth rate and size. For instance, some dwarf tarantulas may molt every few weeks, while larger species may only molt once or twice a year.

Signs of a Tarantula Preparing to Molt

As a tarantula owner, it is important to know the signs that your pet is preparing to molt. Here are some common signs to look out for:

  • Decrease in activity: A tarantula preparing to molt will often become less active and move around less. This is because they conserve energy before molting.
  • Refusal to eat: Tarantulas may stop eating for a few weeks before molting. This is because they need to shed their old exoskeleton, and a full stomach can make this process more difficult.
  • Bald spot: Some tarantulas may develop a bald spot on their abdomen before molting. This is because they are preparing to shed their old exoskeleton.
  • Dull coloration: Tarantulas may appear dull or faded in color before molting. This is because their old exoskeleton is about to be shed, and the new one has not yet hardened and darkened.
  • Increased use of webbing: Tarantulas may spin more webs than usual before molting. This is because they use their webs to create a safe space for molting.

  • Low appetite: Tarantulas may have a decreased appetite before molting. This is because they need to shed their old exoskeleton, and a full stomach can make this process more difficult.

It is important to note that not all tarantulas will display these signs before molting. Some may molt without any noticeable changes in behavior or appearance. However, if you notice any of these signs in your tarantula, it is best to be prepared for a molt. Make sure your tarantula has access to fresh water and a safe space to molt, and avoid handling them during this time.

Caring for a Molting Tarantula

As a tarantula owner, it is important to know how to care for your pet during the molting process. Molting is a vulnerable and stressful time for your tarantula, and improper care can lead to serious health issues or even death. In this section, I will provide tips on how to care for your tarantula both before and after molting.

Pre-Molt Care

Before your tarantula molts, there are a few things you can do to ensure a successful molt. First, make sure your tarantula is well-fed and hydrated. A well-fed tarantula will have the energy and nutrients necessary for a successful molt. Additionally, make sure the tank is clean and free of debris, as a dirty tank can lead to infection.

During the pre-molt stage, your tarantula may become less active and stop eating. This is normal behavior, and you should not handle your tarantula during this time. Handling can cause stress and may interfere with the molting process.

It is also important to maintain proper humidity levels in the tank. Most tarantulas require a humidity level of 70-80% during the pre-molt stage. You can achieve this by misting the tank daily or by using a humidifier.

Post-Molt Care

After your tarantula has molted, there are a few things to keep in mind. First, do not handle your tarantula for at least a week. A newly molted tarantula is vulnerable and may be more docile than usual. Handling can cause stress and may lead to injury.

Your tarantula may also exhibit a behavior known as the “death curl” after molting. This is a normal behavior where the tarantula curls up into a ball. However, if your tarantula remains in the death curl for an extended period of time, it may be a sign of health issues.

It is also important to maintain proper humidity levels after molting. Most tarantulas require a humidity level of 70-80% after molting. You can achieve this by misting the tank daily or by using a humidifier.

In conclusion, caring for a molting tarantula requires attention to detail and proper care. By following these tips, you can ensure a successful molt and a healthy pet.

Potential Molting Issues and Solutions

Common Molting Problems

Molting is a natural process for tarantulas, but it can also be a stressful and dangerous time for them. As a tarantula owner, it is important to be aware of the potential molting problems and how to address them.

One common issue is the death curl, where the tarantula curls up and appears to be dead. This is a natural part of the molting process, but it can also be a sign of sickness or stress. If your tarantula is in the death curl for an extended period of time, it may need to be moved to an ICU container to prevent further stress.

Another issue is when the tarantula gets stuck in its old skin, which can lead to injury or death. To prevent this, make sure the tarantula has a moist substrate and a hide to molt in. If the tarantula does get stuck, do not attempt to remove the old skin yourself. Instead, consult a vet for assistance.

When to Consult a Vet

While some molting issues can be addressed at home, there are times when it is necessary to consult a vet. If your tarantula is not showing signs of molting or if it has been in the death curl for an extended period of time, it may be sick and in need of medical attention.

Other signs that your tarantula may be sick include a lack of appetite, lethargy, and abnormal behavior. If you are unsure if your tarantula is sick or if you have any questions or concerns about its molting process, it is always best to consult a vet for advice.

Remember, the molting process can be a stressful and dangerous time for your tarantula, but with proper care and attention, you can help ensure a successful molt.

Feeding and Molting

As a tarantula owner, I know that feeding and molting are two crucial aspects of keeping my pet healthy and happy. In this section, I will discuss the relationship between feeding and molting, and provide tips on how to ensure your tarantula is getting the proper nutrition before and after molting.

Diet Before Molting

Before molting, tarantulas will often decrease their appetite and become less active. This is because they are preparing for the molt and need to conserve energy. It’s important to continue feeding your tarantula during this time, but be mindful of the amount and type of food you offer.

Offer your tarantula smaller prey items, such as crickets or other insects, as they will be easier for your tarantula to digest. You should also avoid feeding your tarantula too close to the molting period, as uneaten prey can cause stress and potentially harm your tarantula during the molt.

Additionally, make sure your tarantula has access to clean water at all times, as hydration is crucial for a successful molt.

Diet After Molting

After molting, your tarantula will need to rebuild its exoskeleton and grow. This means it will require a nutrient-rich diet to support its growth. Offer your tarantula larger prey items, such as crickets or other insects, to ensure it is getting enough protein and other essential nutrients.

It’s important to note that your tarantula may not eat immediately after molting, as it can take some time for its new exoskeleton to harden. Be patient and continue to offer food, but do not force your tarantula to eat if it is not interested.

In addition to feeding, silk is also important for a successful molt. Your tarantula will use silk to create a molting mat, which provides a soft surface for it to molt on. Make sure your tarantula has access to plenty of silk before and after molting.

Tarantula Species and Molting Patterns

Common Pet Tarantula Species

There are many different species of tarantulas, each with its own unique characteristics and molting patterns. Some of the most common pet tarantula species include the Brachypelma, Aphonopelma, and Grammostola.

Brachypelma species are known for their bright colors and docile temperament. They typically molt once a year, although some individuals may molt more frequently. Aphonopelma species, on the other hand, are more variable in their molting patterns. Some may molt as frequently as every few months, while others may only molt once a year. Grammostola species are similar to Brachypelma in terms of their molting frequency, typically molting once a year.

Species-Specific Molting Patterns

In addition to the general patterns described above, each species of tarantula may have its own unique molting patterns. For example, some species may molt more frequently when they are young, while others may molt more frequently as adults. Some species may also molt more frequently in response to changes in temperature or humidity.

It is important to research the specific molting patterns of your tarantula species in order to provide the best care possible. This may involve consulting with experts in the field, such as veterinarians or experienced tarantula owners, as well as using online resources and other sources of information.
