Joro spiders thrive in warm, humid regions. That’s why they’ve settled comfortably in southeastern U.S. states like Georgia, South Carolina, and North Carolina.
Like most orb-weaving spiders, Joros are drawn to areas with abundant insect life. Gardens, wooded backyards, and areas with standing water attract bugs—and bugs attract spiders.
Joro spiders build their webs high above the ground, often between trees or poles. They prefer locations where they can stretch their large, golden silk webs without much disruption.
Surprisingly, human activity indirectly attracts Joro spiders. Outdoor lighting lures bugs at night, and spiders follow the food source. They are often found near patios, porches, and garages.
Joro spiderlings use “ballooning” to travel through the air on silk threads. They often settle where the wind drops them—especially in open, breezy areas with plenty of vertical support.
In the U.S., few predators target Joro spiders, allowing them to multiply rapidly in areas where they feel secure and unthreatened.
Quiet spaces like tool sheds, wood piles, and fence lines offer perfect nesting spots. Joros favor undisturbed areas where they can anchor large webs without interference.
