After what was the second largest gypsy moth eradication ever this past spring, the Washington State Department of Agriculture announced that no spraying will take place in 2017.
In 30,000 traps placed over the summer, WSDA caught 25 European gypsy moths. None of the more destructive Asian gypsy moths were found this year and no moths were found in the areas where WSDA treated for gypsy moths earlier this spring.
Because neither Asian gypsy moths nor reproducing European gypsy moths were found, WSDA will not need to spray for gypsy moths next year.
“This spring’s treatment results are very encouraging,” WSDA Director Derek Sandison said. “The community support for this work continues to help protect our environment from this destructive pest.”
Moths were caught throughout the state this summer. Many of these catches are likely new introductions that came with people moving from the Midwestern and Eastern states that are infested with gypsy moth. “New England had its largest gypsy moth outbreak in 30 years this summer. With outbreaks in other areas, we expect to see more catches in our state,” said Jim Marra, Pest Program Manager for WSDA’s gypsy moth program.
WSDA will continue the effort next summer, when trappers will place 20,000 – 30,000 traps statewide.
