The November 7 discovery of a Northern giant hornet in Aldergrove brings the total number of positive reports in the Lower Mainland to five since 2019.
Most recently, two separate reports were confirmed just five kilometres apart, likely due to the hornets leaving their nests to look for mates. Each of the positive reports of a Northern giant hornet was submitted by the public. Surveillance by the province continues, along with tactics such as laying traps, however no nests have been discovered in the Lower Mainland as yet. The continued efforts of the public will be crucial to preventing Northern giant hornets from becoming established in BC.
If you think you have seen a Northern giant hornet in BC, report it to the Invasive Species Council of BC at 1-888-933-3722, via the “Report Invasives” mobile phone app, or at bcinvasives.ca/report.
