Atlanta, GA, August 19, 2026 — Joro spiders, known for their large size and vibrant yellow and grey markings, are making a notable return to the Atlanta area this season. These arachnids, scientifically identified as *Trichonephila clavipes*, are a type of orb-weaver spider that first appeared in the United States several years ago. Their presence has become an annual occurrence in many parts of the Southeast, including Atlanta, particularly during the warmer months.

The Joro spider is an invasive species that has established a significant population in Georgia. While their size can be startling, experts generally describe them as harmless to humans and pets. Their large, intricate webs, often spanning several feet, are a common sight in gardens, on porches, and between trees and shrubs during late summer and fall.

Entomologists note that Joro spiders play a role in controlling populations of flying insects. Despite their intimidating appearance, their venom is not considered medically significant to humans, and they are not aggressive. If encountered, the recommended approach is to leave them undisturbed or to relocate them if they are in an inconvenient location.

The return of the Joro spider is a predictable ecological event in the region. While their population numbers can vary from year to year, their presence continues to be a recurring feature of the Atlanta landscape during the late summer and early autumn.
