WSU scientists will start trapping queen murder hornets this spring, hoping to wipe out the species. State officials have also launched an app for hornet sightings.

"The most likely time to catch Asian giant hornets is from July through October -- when colonies are established and workers are out foraging," the WSU Department of Agriculture stated. "Traps can be hung as early as April if attempting to trap queens, but since there are significantly fewer queens than workers, catching a queen isn't very likely."
