The United States faces a deadly threat from the giant killer wasp, known as the “murder hornet.” This invasive insect, the largest and most dangerous of its kind, first appeared in the country in 2019. It continues to spread fear and havoc.

The latest sighting occurred in Washington in 2021. The Washington State Department of Agriculture (WSDA) reported the 4.4-centimeter insect on August 11, just 3.2 kilometers from its initial 2019 sighting near Blaine, Washington. This “murder hornet” is known for its aggressive behavior and ability to attack anything in its path.

“Murder hornets” are notorious for wiping out entire beehives with their formidable mandibles. They kill and decapitate thousands of bees, taking over the hive and feeding their offspring on the brood. Their venomous sting can be lethal to humans, although fatalities from a single sting are rare.

In response, the WSDA is setting up live traps and tagging captured wasps to locate their nests. Officials near the US-Canada border are also installing traps to prevent further spread.
