Blog: The Japanese Giant Hornet is here

Delta BC

A giant Japanese hornet was discovered here in the Lower Mainland which is thought to have arrived on a container ship from Asia. It is extremely dangerous to both humans and bees. The Japanese giant hornet is one of the world's largest hornets, growing longer than 4 centimeters. Japanese giant hornet workers forage for a wide range of insects, including crop pests, so the hornets are regarded as very valuable. The workers dismember the bodies of their prey returning with the most nutrient-rich body parts. The workers chew the prey into a paste before feeding the larvae - which in return produce a fluid consumed by the workers. Once a Japanese giant hornet has located a honey bee hive, it can kill 40 bees per minute, while a group of 30 hornets can destroy an entire hive containing 30,000 bees in a couple hours. They are very aggressive if incited and its venom attacks the nervous system and damages the tissue of its victims. Being stung is extremely painful and can require hospitalization.
