Are tarantulas dangerous?
The idea of having a tarantula within the home may not appeal to everyone, but these unusual exotic pets attract many spider enthusiasts. Tarantulas often suffer from misconceptions and misinformation. In this article, we clarify the facts behind some of the most common questions and myths about tarantulas, helping you understand their true nature and care requirements.
Are tarantulas hard to keep as pets?
Compared to many other animals, tarantulas are relatively low-maintenance pets. Unlike dogs or cats, they do not require daily interaction or training. In fact, expert advice generally recommends avoiding handling tarantulas as this can stress them and increase the risk of bites.
Tarantulas are clean, quiet creatures that occupy little space and need minimal daily care beyond maintaining a clean enclosure and providing suitable temperature and humidity. However, as exotic and venomous animals, their health can pose challenges. Most regular vets are not trained or equipped to treat tarantulas, so responsible owners often seek specialised exotic pet vets.
Do tarantulas bite, and how dangerous are they?
Tarantulas have earned a fearsome reputation, often amplified by films and media portraying them as aggressive predators. In truth, they are usually docile and prefer to retreat rather than attack larger animals or humans.
A bite generally occurs only if a tarantula feels trapped or threatened and cannot escape. While their venom is typically no more potent than a bee sting, a bite can cause pain, inflammation, and irritation. It's important to note some people may have allergic reactions similar to bee allergies, including rare anaphylactic shock.
Different tarantula species vary in venom strength and temperament. Starter species like the Chilean Rose and Mexican Redknee tend to be less aggressive with weaker venom, making them better suited for first-time tarantula keepers.
Can tarantulas harm you besides biting?
Many New World tarantulas defend themselves by flicking tiny, barbed hairs called "urticating hairs" from their abdomens. These hairs can irritate skin and mucous membranes, causing itching and discomfort. While not dangerous, they are best avoided. Getting these hairs in the eyes can cause significant irritation, so care should be taken when cleaning enclosures or handling these spiders.
Do tarantulas eat live prey like mice?
In the wild, tarantulas consume a diverse diet including insects, small rodents, and occasionally birds or other arthropods. Historically, live pinkie mice were fed to tarantulas in the UK. However, this practice is now illegal, and live pinkie mice are not commercially available as food.
Most UK tarantula keepers now use frozen and defrosted pinkie mice instead. It can sometimes be challenging to encourage tarantulas to recognise non-living food, so patient observation is important. Owners should regularly remove uneaten prey remains using tweezers to maintain hygiene and prevent harm.
Why do tarantulas shed their skin?
Tarantulas moult to grow their exoskeleton. Juveniles moult every few months, while adults typically moult about once a year. The shed skin usually comes off in one piece resembling a hollow spider and is often kept as a curiosity by enthusiasts.
Before and during moulting, tarantulas stop eating and become vulnerable. Leaving live prey in the enclosure during moulting can risk injury, as the tarantula is unable to defend itself. After moulting, their new exoskeleton is soft and takes about a week to harden. Feeding should only resume after this period to avoid harm.
How long do tarantulas live?
Females generally live much longer than males, with lifespans extending from 10 to 20 years in captivity. Some females have even been documented living up to 30 years, though this longevity is rare in the wild. Male tarantulas usually live shorter lives, often dying soon after reaching maturity or mating.
Because of these long lifespans, tarantulas are a long-term commitment and not suitable for owners looking for short-lived pets.
