The so-called “homicide hornet” has been eradicated from the USA, 5 years after the invasive species was first found in Washington state, officers declared Wednesday.

The general public additionally performed a big half in serving to eradicate the pest by reporting sightings, officers stated.
“With out the general public’s assist for this effort, it’s unlikely we might be asserting the eradication of northern big hornet as we speak,” Sven Spichiger, WSDA’s pest program supervisor, stated in an announcement. “All of our nest detections resulted straight or not directly from public reviews. And half of our confirmed detections got here from the general public. The folks of Washington will be proud that we did this by working collectively.”
The northern big hornet, which is native to Asian international locations together with China and Japan, was first detected in North America in August 2019 in British Columbia, Canada. It was confirmed in Washington state 4 months later when a resident in Whatcom County reported a useless specimen. That incident gave the impression to be a separate introduction originating from a unique nation than the British Columbia one, officers stated.
4 hornet nests discovered inside alder tree cavities in Whatcom County have been eradicated between October 2020 and September 2021.
Trapping efforts continued in Whatcom County by 2024, and no further hornets have been detected within the space, WSDA stated.
A neighborhood member reported a “suspicious hornet sighting” in Kitsap County in October, although WSDA was unable to acquire the hornet to substantiate the species, the division stated. Traps positioned within the space and public outreach didn’t yield any further proof or reviews of suspected sightings, it stated.
“All we will say is that the picture seems to be a hornet of some form. The way it got here to be in Kitsap County, we do not know,” Spichiger stated.
WSDA stated it can conduct trapping within the space in 2025 as a “precautionary measure.”
The northern big hornet might have posed a “vital menace” to honey bees and different pollinators had it turn out to be established within the U.S., officers stated. The hornets can kill a complete honey bee hive in simply 90 minutes. Their sting can be extra painful than that of a typical honey bee.
“By tackling this menace head-on, we protected not solely pollinators and crops, but additionally the industries, communities, and ecosystems that rely upon them,” Davidson stated.
