B.C. Monitoring Yellow-Legged Hornet Threat After Invasive Species Found at Washington State Port

British Columbia agriculture officials say they are closely monitoring developments after a live Yellow-Legged Hornet was discovered and destroyed at a cargo port in Washington.

The invasive insect, which poses a serious threat to honey bee populations and agricultural production, was found on April 30 during an inspection of a cargo vessel at the Vancouver port, according to the Washington State Department of Agriculture.

Also known as the southern giant hornet, the species is native to Asia and has spread aggressively across Europe and parts of North America.

Low Risk to British Columbia, Officials Say

A spokesperson for British Columbia Ministry of Agriculture and Food said the province remains in contact with Washington authorities and has been advised that the likelihood of the hornet spreading into British Columbia is currently low.

“The Washington State Department of Agriculture has advised us that there is a low risk of the hornet spreading into B.C.,” the ministry said in a statement.

Provincial officials added that established communication systems and response protocols are in place at both federal and local levels to quickly address any similar discoveries at ports in British Columbia.

Serious Threat to Honey Bees

The yellow-legged hornet is considered one of the most destructive invasive predators of honey bees. The insects attack beehives, killing worker bees and weakening colonies that are vital to pollination and food production.

According to Washington state agriculture officials, the hornet has caused significant damage in Europe, where it has contributed to a 30 per cent decline in honey bee hives and honey production.

Honey bees play a critical role in pollinating crops, including fruits, vegetables, and oilseeds, making their protection essential to both agriculture and biodiversity.

Cargo Ship Inspection Prevented Potential Spread

Sven Spichiger said the hornet was discovered by a grain inspector while examining a cargo vessel.

Officials killed the insect immediately and conducted additional inspections of the ship, finding no further evidence of hornets or nests.

“We are hopeful that this was a one-off interception, which occasionally happens at our ports,” Spichiger said.

Cross-Border Cooperation Underway

Agriculture authorities in both Canada and the United States are working together to monitor invasive species that threaten ecosystems and food security.

The latest incident highlights the importance of early detection and rapid response, particularly as international trade increases the possibility of pests arriving through cargo shipments.

For now, officials say there is no indication that the yellow-legged hornet has established itself in British Columbia, but monitoring efforts will continue to protect local bee populations and the province’s agricultural sector.
