Giant, Flying Joro Spiders Invade East Coast: What You Need to Know

Invasive Species Spreads Across Eastern States

The Joro spider, a massive, flying arachnid native to Japan and Asia, has been spotted in multiple East Coast states, including Georgia, Tennessee, the Carolinas, and Maryland. Scientists expect the species to continue its rapid expansion.

What is a Joro Spider?

The Joro spider is a large, yellow and black spider with a leg span of up to 4 inches. It spawns massive webs and can "fly" up to 100 miles using wind currents.

Are Joro Spiders Dangerous?

According to invasive species expert David Coyle, Joro spiders are docile and do not pose a threat to humans or pets. Their venom is reserved for prey caught in their webs.

Where Are Joro Spiders Found?

Joro spiders have been spotted in states along the East Coast, with sightings confirmed as far north as Maryland. They prefer humid forest areas, similar to their native habitat in Japan.

How to Handle Joro Spiders

Coyle suggests using a broom to sweep away the spider and its web. Since they are not aggressive, there is no need for concern about bites or attacks.

Interesting Facts

• Joro spiders have a one-year lifespan and reach their full size in October, just in time for Halloween.
• They are too heavy to fly when fully grown.
• Their webs can be massive, covering power lines, porches, and vegetable patches.

While Joro spiders may seem intimidating, they are harmless to humans and pets. As their population continues to grow, it's essential to understand and coexist with these fascinating creatures.
