The yellow-legged hornet Georgia response team is entering its third consecutive year of tracking and trapping efforts as the invasive species begins its spring nesting cycle. Georgia Agriculture Commissioner Tyler J. Harper issued an urgent call for residents in Bryan, Bulloch, Chatham, Effingham, Liberty, and Screven counties to report any nest sightings immediately, emphasizing that early detection during the embryo nest window of March through April is the most effective moment to stop a colony before it can grow into a much larger threat later in the season.
The Georgia Department of Agriculture confirmed that by late March 2026, teams had already captured 344 hornets and eradicated three nests in the current season. That compares to 3,700 hornets captured and 18 nests eradicated across all of 2025. Harper described the stakes plainly: by working together, Georgians can protect the state’s number one industry, agriculture, from a pest that targets the very pollinators that keep that industry productive.
Yellow-legged hornet Georgia threat centers on honeybees and crop pollination
The yellow-legged hornet, known scientifically as Vespa velutina, earned the nickname “bee hawk” for its hunting behavior. It swoops down on honeybee colonies, capturing individual bees in the air and at hive entrances. Keith Delaplane, director of the UGA Bee Program and an entomologist at the University of Georgia, described the threat clearly: a few hornets hunting at a hive entrance can intimidate bees from foraging and cause the colony to decline, and a small group of hornets can depopulate an entire apiary in a matter of days even without killing the colony outright.
That threat has direct consequences for Georgia’s agricultural output. Crops including apples, blueberries, cucumbers, and watermelons depend heavily on honeybees and native bees for pollination. Georgia is one of the country’s leading producers of blueberries and peaches, both of which require effective pollination during a narrow seasonal window. A reduction in bee colony strength, whether through direct predation or through the behavioral suppression that hornet hunting causes, translates directly into lower yields and higher production costs for affected growers.

How the yellow-legged hornet Georgia life cycle shapes the response strategy?
The yellow-legged hornet follows a predictable annual life cycle that defines when intervention is most effective. Queens overwinter from December through March, emerging in early spring to build the first embryo nests — small, smooth, paper-like structures roughly the size of a tennis ball, often found on porches, eaves, shrubs, or low tree branches. These embryo nests appear between March and April. From April to June, those embryo nests develop into primary nests, growing from softball-sized to roughly the size of a watermelon. Between June and September, worker hornets expand the colony into large secondary nests capable of housing up to 6,000 individuals.
Officials say eliminating the nests during the embryo stage is far easier and far more consequential than waiting for secondary nest development. A queen eliminated in April does not produce the thousands of workers that would otherwise spend the summer hunting bee colonies. The Georgia Department of Agriculture asks residents to report suspected nests by email at [email protected] and to photograph the nest and any hornets without disturbing them. Residents should not attempt to remove nests themselves, as a displaced queen can simply establish a new colony elsewhere.
Three years of eradication efforts in Georgia with completion still years away
The yellow-legged hornet was first confirmed in the United States in August 2023, when a Savannah-area beekeeper spotted an unusual insect and reported it to state authorities. The Georgia Department of Agriculture, working with USDA APHIS and the University of Georgia, confirmed the identification and immediately began eradication efforts. The species is native to tropical and subtropical Southeast Asia and has spread across much of Western Europe, including establishing populations in France.
The standard for declaring a complete eradication requires three consecutive years with zero detections — a threshold Georgia has not yet reached. In the meantime, the detection zone has remained concentrated in the Savannah coastal area, and officials say the key to preventing wider establishment is the public reporting network that catches embryo nests before they become the large summer colonies that are far harder to control.
