To report an Asian Giant Hornet in BC

Be on the lookout for Asian giant hornets this spring and summer (Province of BC Information Bulletin March 20, 2020)

 

Additional questions answered by Paul van Westendorp:

1. What is the main thing we should tell staff/public to look out for in the field?

Any unusually large wasp-like specimen to be photographed if possible. AGH is most likely to build an underground nest in dense vegetation. 

2. What is the typical range individuals will travel from a nest?

AGH are reported to have a foraging range of up to 8 km. However, if sufficient food is available, they normally range within 1-2 km.

3. What should one do if they agitate a nest?

When a nest is disturbed, remove oneself as quickly as possible and crawl through dense vegetation. DON'T run into the open as one would become an focal point for the hornets. Make sure to remember the nest location. 

4. How best to collect a sample of the AGH?

Due to the potential threat of a serious stinging incident, we don’t encourage anyone to collect a sample. However, when a single insect is sighted (dead or alive) place in a container and freeze. After 10 minutes, remove from the freezer and place specimen on a flat surface and take photographs for prompt ID. Mark the location where the specimen was found and collected. 

5. Are nest sites re-used or abandoned annually?

Under normal circumstances, AGH constructs annual nests only. It may be possible that in warmer climates, a nest manages to survive the winter months if they can access some food sources. It seems highly unlikely in our area of Coastal BC.
