Tarantulas, fascinating creatures though they may be, come with a unique defense mechanism that can pose a serious risk to their owners: urticating hairs. These tiny, barbed hairs are located on the rear of the tarantula’s body and can be launched into the air when the spider feels threatened. If these hairs come into contact with the eyes, they can cause significant irritation and even injury.

The Case of the Corneal Injury

A recent case study published in the prestigious medical journal The Lancet highlights the potential danger of tarantula hairs. A 29-year-old male patient presented with a red, watery eye that had been bothering him for three weeks. Upon examination, doctors discovered fine, hair-like projections embedded in the patient’s cornea, the clear outer layer of the eye.

The patient recalled that three weeks prior to the onset of his symptoms, he had been cleaning his pet Chilean Rose tarantula’s enclosure. As he was focused on removing a stubborn stain, he noticed movement in the terrarium. When he turned his head, he was met with a “mist of hairs” that struck his eyes and face.

Treatment and Prevention

Most of the tarantula hairs were too small to be manually removed from the patient’s eye. Instead, doctors administered a course of steroid eye drops over several months, which successfully reduced the inflammation. The patient was advised to wear eye protection whenever handling his pet tarantula.

While the Chilean Rose tarantula is the species most commonly kept as a pet, it is important to note that other tarantula species also possess urticating hairs. Therefore, all tarantula owners should take precautions to protect their eyes.

Tips for Tarantula Owners

• Always wear eye protection when handling your tarantula. This includes goggles, safety glasses, or a face shield.
• Be aware of your tarantula’s behavior. If your tarantula is agitated or feels threatened, it may release its hairs.
• Avoid sudden movements around your tarantula. This can startle the spider and cause it to launch its hairs.
• Keep your tarantula’s enclosure clean. A clean enclosure will help to reduce the number of loose hairs that can become airborne.
• If you experience any eye irritation after handling your tarantula, seek medical attention immediately.

Conclusion

Tarantula hairs can pose a serious risk to the eyes, but by taking proper precautions, tarantula owners can safely enjoy their pets. By wearing eye protection, being mindful of their tarantula’s behavior, and keeping their enclosure clean, tarantula owners can minimize the risk of eye injury.
