About the Chilean Rose Hair Tarantula

The Chilean Rose Hair Tarantula is one of the most recognizable tarantulas globally and a favorite among arachnid enthusiasts, particularly those just venturing into the hobby. Originating from the deserts and scrublands of Chile, this spider’s gentle disposition combined with its stunning appearance has made it a staple in the exotic pet trade.


The Chilean Rose Hair Tarantula possesses a moderate size, with mature females typically sporting a leg span ranging from 4.5 to 5.5 inches. Males tend to be slightly smaller and more slender in comparison. While not as grand as some other tarantula species, their size is still respectable and offers an awe-inspiring display, especially when the spider is fully splayed out during activities like hunting or web-building.

Unique Features

The name “Rose Hair” stems from the beautiful, delicate pinkish hue found on the carapace, almost reminiscent of a rosy blush. This coloration contrasts starkly against the dark, almost blackish legs and abdomen, which are covered in a dense layer of fine hairs. These hairs, apart from adding to the tarantula’s visual appeal, have a defensive purpose; the tarantula can release these barbed hairs when threatened, which can cause irritation to potential predators.

Behavior and Temperament

The Chilean Rose Hair is famed for its generally docile nature, which has undoubtedly played a significant role in its popularity as a pet. They tend to be calm and slow-moving, often spending prolonged periods in one spot within their enclosure, which has led many enthusiasts to affectionately label them as “pet rocks.” However, like all animals, individual temperaments can vary. While most are placid, occasional individuals may exhibit skittish or defensive behaviors.


Thanks to their typically calm nature, the Chilean Rose Hair is one of the few tarantulas that many enthusiasts feel comfortable handling occasionally. When doing so, it’s essential to move slowly, allowing the tarantula to walk onto your hand rather than attempting to grasp it. It’s also crucial to handle them close to the ground to prevent potential injury from falls. Despite their docile nature, it’s always essential to approach with respect and caution, as they can still bite or flick hairs if they feel threatened.

Diet & Nutrition

In the wild, the Chilean Rose Hair Tarantula preys on a variety of insects. In captivity, they thrive on a diet of crickets, roaches, and the occasional mealworm or superworm. It’s worth noting that, unlike many other animals, tarantulas can go for extended periods without food. It’s not uncommon for a Chilean Rose Hair to fast for weeks or even months, especially before molting. A shallow water dish should always be available in their enclosure, ensuring they stay hydrated.


Native to the scrublands and deserts of Chile, this tarantula is used to a moderately warm environment. Ideal temperatures range between 70°F and 85°F. In most home environments, additional heating may not be necessary, but if it is, an under-tank heater can help achieve the right temperatures. It’s always a good idea to monitor the temperature using a reliable thermometer.

Common Health Issues

While hardy, the Chilean Rose Hair can suffer from a few health issues, particularly if kept in sub-optimal conditions. Dehydration is a potential concern, so always ensure they have access to fresh water. Improper humidity can also lead to molting issues, which can be fatal for the spider. Keeping the substrate slightly damp (but not wet) can help maintain humidity. Mites can also be an occasional issue, usually indicating a problem with cleanliness or humidity in the enclosure.


Breeding the Chilean Rose Hair Tarantula is an exciting venture, but not without challenges. After ensuring a mature male and female are available, they can be introduced into the same enclosure. Males, having a shorter lifespan and being driven to reproduce, will actively seek out the female. However, care should be taken as females can sometimes show aggression towards males post-mating. Following a successful pairing, the female will produce an egg sac containing hundreds of eggs. Over the subsequent weeks, these will develop into spiderlings. Care should be taken to separate the spiderlings once they start moving around to prevent cannibalistic tendencies.
