A black-and-yellow Joro spider in a web
Joro spiders are an invasive species in the US, but they aren't as scary as they seem.
  • Get ready for flying spiders the size of your palm. They could be coming to your neighborhood soon.
  • Joro spiders have been rapidly spreading across the southeast US, and are now moving north.
  • Though venomous, Joro spiders aren't harmful to humans and prefer to stay outdoors.

It sounds like the stuff of nightmares: venomous, monster-sized spiders floating through the air and invading the northeastern US this summer.

But some experts say invasive fruit flies can do more damage than the colorful Joro spider, AP News reported.

It's easy to understand why the spider sounds terrifying, though.
