Tarantula Season in Southern California: What to Expect and How to React

Heads up, hikers and nature lovers in Southern California! If you’re planning to explore Griffith Park or other natural areas this summer and fall, you might encounter some impressive, eight-legged residents: tarantulas. Don’t panic! Understanding their behavior and habits can turn a potentially scary encounter into a fascinating wildlife experience.

Tarantulas in L.A.? It’s More Common Than You Think

Many people are surprised to learn that tarantulas call Los Angeles home. As Tyler Young, an educator at the L.A. County Natural History Museum, points out, these large spiders are often associated with remote deserts, not urban landscapes. But, they’re here, and this is their time to shine (or, rather, scuttle).

Did you know? Southern California is home to several species of tarantulas, including the California Ebony Tarantula and the Desert Tarantula.

Why Are Tarantulas Out and About Right Now?

This increased tarantula activity is all about romance, or rather, the pursuit of it. Mature male tarantulas emerge from their burrows during this season in search of a mate. Unfortunately, this amorous adventure is often their last. Their lifespan is short after mating, typically only a month or so, according to Rick Vetter, a retired research associate at the UC Riverside Entomology Department.

Meet the Steindachner’s Ebony Tarantula

One of the most common species you might encounter is the Steindachner’s ebony tarantula. These impressive arachnids can grow up to 5 inches in size. Imagine that crawling across your path!

What to Do If You See a Tarantula

The best course of action is simple: leave them alone. As Tyler Young emphasizes, California tarantulas are generally docile and will keep to themselves if given the space. Forget the Hollywood horror movies – these aren’t aggressive monsters.

Pro Tip: If you spot a tarantula, observe it from a safe distance. Avoid approaching or trying to handle it. Their fangs, while capable of delivering a bite, are rarely used defensively.

Tarantulas and Your Backyard Pool: A Word of Caution

If you have a pool, be aware that tarantulas can sometimes fall in. Rick Vetter shares stories of people rescuing seemingly lifeless tarantulas, only to be surprised when they “reanimate.” The spiders essentially shut down their breathing in the water and recover once removed. So, if you find one in your pool, carefully scoop it out and let it recover in a safe place away from foot traffic.

The Bigger Picture: Respecting These Ancient Creatures

Beyond the immediate “eek” factor, it’s important to appreciate tarantulas for what they are: ancient creatures with a vital role in the ecosystem. Vetter likens them to sequoias, emphasizing their long lifespan and slow maturation. Male tarantulas live for about eight years, while females can survive for over two decades. Unlike more common spiders like black widows, tarantulas represent a slower, more enduring aspect of nature.
