The Growing Threat of the “Murder Hornet” in the U.S.

Since its first U.S. appearance in 2019, the giant “murder hornet” has posed a serious threat to ecosystems and public safety. This invasive insect, officially known as the Asian giant hornet, is the world’s largest and most dangerous wasp species. Its aggressive nature and lethal capabilities have alarmed entomologists and residents alike.

In August 2021, a live specimen was found in Washington State, just 3.2 kilometers from its initial 2019 sighting near Blaine, according to the Washington State Department of Agriculture (WSDA). Measuring 4.4 centimeters, this hornet attacks anything in its path, including entire beehives. Using powerful mandibles, it can decapitate thousands of bees, occupy their hive, and feed the brood to its offspring—devastating local pollinator populations.

Though rare, a sting from the murder hornet can be fatal to humans due to the large amount of venom injected.

To combat the spread, the WSDA has deployed traps and plans to tag captured hornets to locate and destroy nests. Its presence near the U.S.-Canada border has also prompted Canadian authorities to take preventive action.

The rise of the murder hornet is a stark reminder of nature’s potential dangers—and the urgent need for invasive species control.
