Why Are Old World Tarantulas Harder to Keep Compared to New World Species?

Old World tarantulas, including those from Africa, Asia, and Europe, are generally considered more challenging to keep as pets compared to New World tarantulas from the Americas. This guide explores why these differences exist and provides insights for pet enthusiasts considering these exotic arachnids.

Temperament Differences

Old World tarantulas often exhibit more defensive and aggressive behaviors. They are less tolerant of handling and are more likely to bite when threatened. In contrast, New World species are generally more docile, reducing the risk of accidental bites during routine care.

Venom Potency

Many Old World tarantulas possess potent venom. While both types can deliver painful bites, the reactions from Old World bites can be more severe. This presents a greater risk for potential health issues, making them riskier to keep, especially for beginners.

Environmental Requirements

Old World tarantulas typically require specific humidity and temperature conditions to thrive. They often need a drier environment compared to many New World species, which can complicate care and require more careful monitoring and adjustment of their enclosure conditions.

Burrowing Behavior

Many Old World species are burrowers and prefer deeper substrate to mimic their natural behavior. This can make setting up their enclosures more complex, as proper substrate depth and layering are crucial for their well-being. New World species, on the other hand, may not have such specific substrate requirements, making them easier to maintain in a standard enclosure setup.

Stress Sensitivity

Old World tarantulas are generally more sensitive to stress and can experience health issues if the environment is not optimal. They may be more prone to injuries or illnesses if frequently disturbed or startled, making them more challenging to care for in a pet environment.

Availability of Information

There is typically more information and resources available for New World tarantulas, making them easier for beginners to care for effectively. This can be crucial for novice pet keepers who may not have extensive experience or knowledge about tarantulas.

Practical Considerations for Keeping Old World Tarantulas

While Old World tarantulas are more challenging to keep, they are not entirely unsuitable for experienced enthusiasts. However, for the average pet keeper, these species can be riskier due to their unpredictability, tendency to bite, and quick reactions.

When keeping Old World tarantulas, it is essential to approach their enclosure management with extra care. The primary concerns include ensuring the enclosure is secure and preventing the tarantula from escaping during routine tasks such as feeding or cleaning. This can be particularly challenging, as these species may move quickly and erratically when threatened, potentially leading to multiple bites in a short period.

Consequences of Handling Old World Tarantulas

The unpredictability and aggressive behavior of Old World tarantulas make them less suitable for owners who are inexperienced or easily intimidated. Even experienced handlers are advised to approach these spiders with caution, as accidents can easily occur. The consequences can be significant, ranging from minor injuries to severe allergic reactions in some cases.

While it is possible for Old World tarantulas to be kept safely, it is crucial to prioritize the safety of both the pet and the handler. This involves careful observation, proper handling techniques, and maintaining a well-maintained and secure enclosure. For beginners, starting with New World species is often recommended due to their generally more docile nature and wider availability of care information.

In conclusion, while Old World tarantulas offer a unique and fascinating addition to the tarantula-keeping community, their difficulties in care cannot be overlooked. Understanding these differences and taking appropriate precautions can help ensure the well-being of both the pet and the keeper. Whether you choose to venture into the world of Old World tarantulas, it is important to approach them with the necessary knowledge and caution.
