Despite their large size and bold colors, Joro spiders are shy and unlikely to bite humans. They prefer to avoid confrontation and will flee when disturbed.
While technically venomous like most spiders, their venom is weak and only used to subdue prey. Bites are rare and generally cause mild irritation if anything at all.
Joro spiders eat mosquitoes, stink bugs, flies, and other pests. Many experts suggest they help balance ecosystems rather than disrupt them.
Yes, Joros are non-native. But so far, studies suggest they don’t significantly harm local species or plants. They seem to co-exist with native spiders rather than replace them.
Joro webs shimmer gold in the sun and are known for their strength. They often span several feet, making them hard to miss in your yard.
– Joro spiders likely arrived in the U.S. via cargo shipments from East Asia. Their eggs may have hitched a ride undetected, launching their new home in Georgia around 2013.
Due to their cold tolerance and ballooning ability, Joro spiders could continue to spread northward in the U.S. Researchers are closely tracking their migration and impact.
