Evidence of six sightings of Asian giant hornets, known as murder hornets, in Washington state have prompted an urgent search for a possible nest, NBC News reports.
State agriculture officials are working to find and destroy a nest before the hornets enter their "slaughter phase," when they kill honeybees, which are crucial for pollinating some of the state's staple crops, such as raspberries and blueberries.
Murder hornets' attacks on honeybee hives tend to increase around this time of the year, said Sven-Erik Spichiger, a department entomologist, during a virtual news conference Friday.
