Asian giant hornets are unwelcome on both sides of the Canada-U.S. border and officials and citizen scientists will be trapping and exterminating accordingly.
B.C. and Washington state governments co-hosted a virtual press conference Wednesday to discuss their co-operative efforts to find and eradicate the invasive hornets.
A B.C. ministry of agriculture press release noted that 害羞草研究所渃omprehensive surveys害羞草研究所� will take place in Nanaimo and the Cowichan Valley on Vancouver Island and in between White Rock and Aldergrove in the Fraser Valley. Washington announced changes to its trapping efforts and hopes 害羞草研究所渃itizen scientists害羞草研究所� will help set up traps baited with orange juice and brown sugar syrup.
Provincial apiculturist Paul van Westendorp said he害羞草研究所檚 grateful for a pheromone 害羞草研究所渕agic elixir害羞草研究所� provided by the Washington State Department of Agriculture that will be used in some traps. There were about 60 traps, baited with orange juice and rice wine, set up in areas close to the U.S. border last year and van Westendorp said a greater number of traps will be set this year 害羞草研究所渟imply because of the increased activity that is taking place in Washington state.害羞草研究所�
Last year, six hornet specimens were collected in the Fraser Valley, all found by members of the public, and none were found on Vancouver Island. The province says the Island 害羞草研究所渃ould be declared Asian giant hornet-free害羞草研究所� if no more of the insects are found there this year.
Van Westendorp said numerous agencies, beekeepers and other members of the public will play a 害羞草研究所渃ritical害羞草研究所� role in the success of the survey efforts and said the province will be providing more information about trapping.
He said Asian giant hornets, as an apex predator, are not very densely populated in their natural range.

Sven-Erik Spichiger, managing entomologist with the WSDA, said the giant hornets found in Nanaimo in 2019 were genetically linked to giant hornets from Japan, whereas the hornets found in Blaine, Wash., were more closely linked to hornets in South Korea. Van Westendorp said that suggests separate introductions of the species has happened and can happen again.
Asian giant hornets have been called 害羞草研究所榤urder hornets害羞草研究所� because of their propensity to decapitate honeybees. Van Westendorp said the hornets are hazardous to humans, pets and livestock and not only kill bees, but also wasps and yellow jackets, which could cause unknown impacts on ecosystems.
