Jacqueline Serrano, Ph.D., holds a northern giant hornet (Vespa mandarinia) in a cold room with forceps. This hornet was from the first nest that was located and eradicated in Washington state in 2020. Serrano supplied lures that helped capture live hornets, which led WSDA to the nest. Serrano is now working to identify new attractants for the hornets, including pheromones.
