Asian Giant Hornets Eliminated From the United States

After years of dedicated effort, the United States has officially eradicated the Asian Giant Hornet, a dangerous invasive species first discovered in Washington state in 2019. The announcement, made by the Washington State Department of Agriculture (WSDA) and the U.S. Department of Agriculture (USDA), marks a significant victory for both environmental and agricultural communities.

The eradication required an unprecedented level of cooperation among local, federal, and even international agencies. Community groups, particularly in Washington’s Whatcom County, played a critical role by reporting sightings and supporting efforts to locate nests.

Key details from the WSDA’s statement:

• No sightings reported for the past three years.

• A total of four nests eradicated between 2020 and 2021.

• Ongoing precautionary traps will remain active through 2025.

Dr. Mark Davidson, Deputy Administrator at USDA’s Animal and Plant Health Inspection Service, celebrated the achievement, stating, “The success of this effort demonstrates what’s possible when agencies and communities unite toward a common goal.”

Nicknamed “murder hornets,” Asian Giant Hornets posed a grave risk to honey bees and other vital pollinators. A single hornet could decimate an entire hive within an hour, threatening not just bee populations but the crops and ecosystems they sustain.

These hornets also presented a more dangerous sting to humans than that of honey bees, raising additional safety concerns. Early intervention was critical to preventing their establishment.

The hornets’ origins in North America were traced to two separate introductions. DNA evidence indicated that hornets discovered in British Columbia, Canada, and Washington state in 2019 came from different countries. The first nest, located in an alder tree cavity, was eradicated in October 2020. Subsequent nests followed in 2021.

Officials remain vigilant despite the species’ official eradication. An unverified sighting in October 2023 prompted additional trapping in the region, with no further evidence found.

This successful eradication effort underscores the dangers posed by invasive species and highlights what’s possible with swift and coordinated action. Beyond protecting pollinators and agriculture, this victory ensures the preservation of entire ecosystems that could have been irreparably harmed.

It’s a rare piece of good news in the fight against environmental threats proof that determination and collaboration can overcome even daunting challenges.
