Ensuring your tarantula receives proper nourishment is an integral part of their care, directly influencing their ability to thrive in captivity.
Diet and Feeding Frequency
Horned Baboon Tarantulas are primarily insectivores. They should be fed a diet consisting of live insects, such as crickets, roaches, mealworms, and other commercially available feeder insects. The size of the insects should correspond to the size of the tarantula; the prey should be no larger than the tarantula’s body. For spiderlings, feed every 2-3 days, while juveniles can be fed every 4-7 days. Adults typically need to be fed once a week or every other week, depending on their appetite and size. Always remove any uneaten prey within 24 hours to prevent them from stressing or injuring your tarantula. It is also beneficial to gut-load the insects you are feeding to your tarantula, providing them with extra nutrition before they are eaten.
Watering and Hydration
Providing a constant source of fresh water is essential for your Horned Baboon Tarantula. This can be achieved by using a shallow water dish that is easily accessible and difficult for the tarantula to tip over. The dish should be cleaned and refilled with fresh water regularly, at least once a week. Alternatively, you can provide moisture by misting the enclosure lightly every few days, which allows the tarantula to drink water droplets. It is crucial to avoid making the substrate overly wet, as excessive moisture can lead to mold growth and health problems. Regularly monitor the water source and ensure it remains clean and accessible at all times to maintain the proper hydration levels for your tarantula.
Handling and Safety

If you observe any of these behaviors, it is best to leave the tarantula alone and to address any potential environmental stressors. Make adjustments to their environment to mitigate the stress. Ensure that the temperature and humidity are appropriate and that the enclosure provides adequate hiding places. Providing a comfortable and secure environment is essential to minimizing stress and maintaining the overall health of your tarantula.
Molting and Growth

Molting is a natural and essential process for tarantulas, allowing them to grow and replace their exoskeleton. During this process, the tarantula sheds its old exoskeleton to reveal a new, larger one. Understanding the molting process and providing proper care during this sensitive time is crucial for the tarantula’s survival and development. Proper care and environmental adjustments during molting ensure that the new exoskeleton forms correctly, allowing the tarantula to grow and thrive. The process can take various lengths of time, depending on the tarantula’s age and health, so patience and attention to detail are essential for responsible tarantula care.
Understanding the Molting Process
Before molting, your Horned Baboon Tarantula will typically stop eating and may become more reclusive, often retreating to a hide. The tarantula will then lay on its back, and its exoskeleton will split open, allowing the tarantula to emerge. The new exoskeleton is soft and vulnerable, and the tarantula will remain in a vulnerable state for several days. The frequency of molting decreases as the tarantula ages. Spiderlings will molt more frequently than adults. Ensure the enclosure is free of any potential hazards during the molt, such as items that could topple over or injure the tarantula. Do not disturb your tarantula during this process and avoid feeding it until its fangs have hardened after the molt.
Post-Molting Care
After molting, your Horned Baboon Tarantula will be very vulnerable. The new exoskeleton is soft and will take several days to harden fully. Do not attempt to handle the tarantula during this period. Provide the tarantula with a fresh supply of water. After the fangs have hardened, you can begin feeding, but start with small, easily manageable prey items. Ensure that the environment is stable and free from stressors during this time. The tarantula’s overall health and growth depend significantly on the quality of care provided after the molt. Continue to monitor the tarantula’s behavior and ensure that it is eating and drinking normally after the molting process.

Breeding tarantulas can provide a fascinating insight into their life cycles and contribute to the conservation of the species. Careful preparation and adherence to specific care protocols are crucial for the successful breeding of Horned Baboon Tarantulas.
Sexing Your Tarantula
Sexing your Horned Baboon Tarantula is essential for breeding. The most reliable method is to examine the underside of the tarantula after a molt. Male tarantulas will have a pair of modified appendages called palpal bulbs at the end of their pedipalps (the small appendages near the mouth). Females will not have these. Another way to sex them is to look for the spermathecae (sperm storage organs), which are visible inside the molt of a female. Determining the sex of your tarantula accurately is crucial for a successful breeding attempt.
Mating and Egg Sac Care
Mating involves introducing a mature male to a receptive female. The female can sometimes be aggressive, so be prepared to separate them if the mating attempt is unsuccessful or if the female shows signs of hostility. If mating is successful, the female will eventually produce an egg sac. Provide appropriate environmental conditions, including optimal temperature and humidity, for the egg sac to develop. After the eggs hatch, provide the spiderlings with plenty of small food sources. The egg sac needs careful handling and monitoring. The female may or may not eat. Separate the spiderlings to prevent cannibalism as they grow.
