North Carolina warns of invasive hornet threatening bees and crops

North Carolina agriculture officials confirmed the state’s first yellow-legged hornet on July 27 and asked beekeepers to watch for the predator hornet. The finding turned a pest that had been a regional warning into a live threat for Wake County, where backyard beekeepers, gardeners and small farms depend on pollinators to keep fruit, vegetables and landscaping productive.

NC State Extension describes the yellow-legged hornet as a predatory wasp that attacks honey bee colonies. That puts local honey production at risk and could add pressure to colonies already coping with disease, weather swings and other stress. In Wake County, where pollination supports everything from backyard fruit trees to community gardens and commercial crops on the county’s rural edges, a decline in bees could ripple through harvests and raise costs for growers and hobbyists alike.

The first confirmed detection in North Carolina came after a Union County resident noticed unusual hornet activity and reported it to officials, according to a July 29 notice from the Union County Center. That path matters for Wake County residents as well: early detection depends on accurate sightings, not assumptions. Officials have already created a Yellow-Legged Hornet reporting page and report form, signaling that the state is still trying to map where the invasive insect is and how far it may spread.

State agriculture officials were warning about the same pest before the North Carolina confirmation. In a May 9, 2024, notice, NCDA&CS called the yellow-legged hornet a new invasive pest to watch for after it had been found in South Carolina. That earlier alert shows the species has been on the state’s radar for more than a year, but the July confirmation made the concern immediate for North Carolina beekeepers.

For Wake County residents, the practical step is simple: do not guess. If a hornet or large wasp looks unusual, especially near hives or in repeated hunting patterns, report it through NCDA&CS’s Yellow-Legged Hornet reporting page and report form so specialists can verify it. Native bees and wasps play important roles in local ecosystems, and the state’s warning is aimed at stopping a real invader before it can spread deeper into North Carolina’s pollination network.
