On October 22, 2020, the first Giant Asian hornet, or murder hornet, nest was discovered near Washington DC. Fortunately, by October 28, the nest, housing over 500 murder hornets, was contained and destroyed. 200 queens hornets resided in the nest, and if given enough time, these queens could have each created a new hive. The hive was a relatively small size, only containing 776 cells, while a larger nest can have up to 3,000 cells.
The first murder hornet hive in North America was spotted in 2019 on Vancouver Island, Canada. This alarmed many WSDA entomologists because it meant that the murder hornets could have also made hives in America as well. As its name implies, the Giant South Asian murder hornet is native to Asia and is the largest species of hornet. It’s believed that the murder hornets were first introduced to North America by an Asian cargo ship, but it’s unclear if that is what really happened.
A murder hornet sting, also called acid spray, isn’t lethal to a person unless the person is stung over 30 times. Fortunately, these hornets do not target humans unless they come too close, but as an invasive species, they do pose a large threat to the bees population. The murder hornets prey upon many types of bees and can kill an entire beehive in a matter of hours. While this does not immediately affect most people, it is detrimental to farms and plant nurseries that rely on bees to cross-pollinate. This is exactly what the Washington State Department of Agriculture(WSDA) entomologists are concerned about. Many local community members of Virginia also share the concern about an invasion. Katie Rhodes, a biology teacher at Midlothian High school, states, “It’s honestly frightening that an invasive species can harm so much of an ecosystem just by being in it.”
