Pest Alert: Asian Giant Hornet
Three Asian Hornets (Vespa mandarinia)  were found in the Nanaimo area on Vancouver Island in mid-August of 2019.  The identification has been confirmed by Canadian and international experts. This is the first time this insect has been found in British Columbia.  Please report it if you see it:

  • Residents along Zero Avenue — the 16-km-long east-west street that frames the Canada-US border — are being asked to report sightings of the invasive species, as they could emerge from their nests over the coming weeks and months as the weather becomes progressively warmer.

British Columbians who think they may have seen one are asked to take a photo and GPS location if possible and report the sighting to
