With the Asian giant hornet once again being spotted in British Columbia, experts are trying to determine how many nests there are and their location.

CBC News in B.C. spoke with U of G emeritus professor Gard Otis about the issue. Otis specializes in bee behaviour and forest entomology in the School of Environmental Sciences.

“There isn’t any evidence yet that these hornets have become fully established,” said Otis. “But the fact that a new hornet was found (in a different location) is a concern also, because that could be a different source colony or something.”

Asian giant hornets hunt insects and are generally not looking to engage with people, pets or large animals, the B.C. agriculture ministry said in the story.

Otis was interviewed by several media outlets in May on the hornets.
