costa rican zebra tarantula

Costa rican zebra tarantula also known as the striped-knee tarantula, is a visually striking species featuring a black body adorned with deep red hairs, distinctive white stripes on its legs, and bright orange spinnerets. This tarantula is best suited for experienced keepers due to its skittish temperament and quick movements, which can make handling challenging. As a pet, it is relatively low-maintenance, requiring weekly feedings and occasional habitat cleanings. However, its care demands a level of expertise and understanding of its behavior to ensure a safe and healthy environment.

Costa Rican Zebra Tarantula Behavior and Temperament

Costa Rican zebra tarantulas are known for their impressive speed, making them less ideal for those who enjoy handling their pet spiders. Although generally docile, they can move swiftly when startled, which makes them difficult to catch and handle safely. This quickness can lead to potential injuries for both the spider and the handler. Experienced tarantula owners, however, may manage to handle them gently and without incident.

While these tarantulas are not usually aggressive, they can bite if they feel threatened, and their venom is toxic. Additionally, they can flick barbed hairs from their abdomen as a defense mechanism, which can cause skin irritation and eye damage. It’s crucial to wash your hands after handling the spider or anything in its habitat and avoid touching your face.

Despite these defensive traits, Costa Rican zebra tarantulas are relatively low-maintenance pets. They require a few hours per week for feeding and cleaning, and they are quiet, solitary creatures that do not need social interaction. They should be housed alone and kept away from other household pets to prevent stress and injury.

Size Information

The Costa Rican zebra tarantula typically boasts an average leg span of 4 to 5 inches, but can sometimes extend up to an impressive 6 inches.

A 5- to 10-gallon aquarium is ideal for housing Costa Rican zebra tarantulas. The tank’s length should be approximately three times the spider’s leg span, with a width two to three times the leg span and a height of about a foot. Alternatively, specially designed spider terrariums offer enhanced safety and easy access.

To create a comfortable habitat, include a hollow log, cork bark, a halved small clay flowerpot, or a store-bought spider house for shelter. Adding various climbing supports like fake plants and vines can also enrich the enclosure.

Maintain the habitat temperature between 70 to 85 degrees Fahrenheit (21 to 30 degrees Celsius) with a humidity level of 75 to 80 percent. Supplemental heating is generally unnecessary unless your home is particularly cool. In such cases, use a specially designed heating pad placed under one side of the habitat to allow the spider to regulate its temperature by moving to a cooler area if needed. The evaporation from the spider’s water dish typically suffices to maintain the required humidity, but if levels drop too low, misting the enclosure can help.

What Do Costa Rican Zebra Tarantulas Eat & Drink ?

Like most tarantulas, the Costa Rican zebra tarantula is a carnivore that prefers live prey, with a strong preference for crickets. It can also consume other insects that are smaller than its body, and an occasional pinky mouse can be offered for added protein.

Feeding schedules may vary slightly based on the spider’s age and size, so it’s advisable to consult with your vet for specific recommendations. Generally, adult Costa Rican zebra tarantulas eat once or twice a week, while juveniles require feeding every one to two days. To feed your spider, simply drop the live prey near it. Remove any uneaten prey after 24 hours to avoid stressing the spider, and clean out any leftover remains to maintain a sanitary habitat.

Provide a shallow water dish that is easily accessible to your tarantula for both drinking and humidity. Ensure the dish is shallow enough to prevent drowning and change the water daily. Additionally, remove any wet substrate to prevent bacterial and fungal growth.

Common Health Problems

Pet tarantulas are generally hardy animals that rarely fall ill when kept in the right environment with proper feeding and hydration. However, the fast-moving Costa Rican zebra tarantula is at risk for damaging or deadly falls. Therefore, it’s crucial to ensure your tarantula’s enclosure is secure and to handle it with extreme care, preferably while seated over a carpeted floor to cushion any accidental falls.

If your spider refuses to eat, appears listless, and is lying on its back with its legs in the air, there’s typically no need for concern. These are signs of imminent molting, a natural process where the spider sheds its old exoskeleton to form a new one. During this time, avoid handling your pet or offering live prey, as this can damage the fragile new exoskeleton. The molting process usually takes a few weeks to complete.


Although tarantulas are generally restful creatures, they still require physical activity to maintain good body condition. By providing a spacious enclosure, you can ensure that your pet tarantula gets the exercise it needs to stay healthy and active.


Tarantulas typically don’t require any grooming assistance from their owners. Molting is their natural way of grooming and renewing themselves. By minimizing stress and maintaining the proper temperature and humidity levels in their environment, you can ensure that your tarantula molts successfully and remains healthy.

Upkeep Costs

The primary ongoing expense for keeping a tarantula is its diet, which typically costs around $5 to $10 per month. You can reduce this cost by raising crickets yourself instead of purchasing them from a pet store. Additionally, plan to spend about $10 to $20 periodically for substrate changes and replacing worn items in the tank. Remember to budget for routine and emergency veterinary care to ensure your tarantula remains healthy.

Pros & Cons of Keeping a Costa Rican Zebra Tarantula as a Pet

Costa Rican zebra tarantulas make for unique and fascinating pets. They are quiet, require minimal space, and don’t demand much of your time. However, it’s important to be mindful of their defense mechanisms and their speed, which can make handling challenging. Despite these considerations, they can be a rewarding pet for those who appreciate their distinctive qualities.
