In 2004, a single female Asian hornet, known scientifically as Vespa velutina, arrived in France hidden inside a shipment of Chinese pottery meant for bonsai cultivation. The pottery was imported by a nurseryman in Pinel-Hauterive, Lot-et-Garonne, and passed through the port of Le Havre before reaching the Southwest. The queen hornet was in a state of diapause, a kind of hibernation-like dormancy, which allowed her to survive the journey. She emerged the following spring and began a colony, marking the start of one of the most rapid biological invasions ever recorded in France.
By the end of 2006, the Asian hornet had already spread to thirteen departments in the Southwest. In the Bordeaux region alone, the number of nests increased dramatically—from just one in 2004 to over two thousand by 2007, as reported in a written question to the National Assembly. This species spreads at an average rate of about 80 kilometers per year, which has allowed it to reach nearly all of France, including Corsica, by August 2024.
The Asian hornet poses a significant threat to bees, which are crucial for pollination. The hornet captures bees as they return to their hives, decapitating them to feed its larvae. A genetic study by researchers at University College of Cork, published in the Journal of Hymenoptera Research, confirmed that the entire European population of this invasive species traces back to that one original queen. Unlike European bees, which have evolved alongside Asian hornets in other parts of the world and can sometimes defend themselves by swarming and suffocating the predator, domestic bees in Europe lack such defenses. The hornet’s hunting method—staying still in front of hive entrances and capturing foragers—exhausts bee colonies, leading to their collapse and weakening beekeeping and crop pollination.
In response to this threat, many individuals and amateur beekeepers have constructed homemade traps using bottles filled with sweet or fermented mixtures. However, these traps are not selective and often attract beneficial insects like butterflies and bees, which are far more numerous than Asian hornets. This lack of selectivity can unintentionally harm pollinators. The most effective method for controlling the hornet remains the targeted destruction of nests, a task usually handled by professionals equipped for safe, high-altitude interventions. Despite being costly and complex to implement on a large scale, this remains the most viable solution.
The spread of the Asian hornet is not confined to France. The species has since expanded across Europe, reaching Spain by 2010 and even being detected in England in 2016. Today, it is found from Portugal to the Netherlands, through Italy. This rapid expansion highlights how global trade can unintentionally transport species that disrupt ecosystems. The story of the Asian hornet in France is a cautionary tale about the challenges of controlling invasive species in an era of increasingly globalized commerce. A single shipment—like a piece of pottery or a cardboard box—can introduce a species that, once established, is nearly impossible to contain.
