Giant Asian 'murder hornets' which kill dozens of people every year are invading western parts of the world. The large insects, which are native to tropical climates, have been spotted several times in the US.
The sightings started in November 2019 along the west coast, but it is unclear who they got there. More than double the size of honeybees, Asian giant hornets have a wingspan measuring more than three inches.
They have a large stinger that contains deadly venom neurotoxin, which can cause cardiac arrest and anaphylactic shock. Conrad Bérubé, a beekeeper and entomologist, was sent to destroy a hive on Vancouver Island, but was stung several times by one.
