Why is the Glassy-winged Sharpshooter a threat to Napa County?

The Glassy-Winged Sharpshooter (GWSS) damages a variety of plants and spreads lethal diseases to crops such as almonds and grapes. It can stress the plants it feeds on, sucking xylem fluids from plants and trees such as crape myrtle, magnolia, oak, hydrangeas, citrus, apples, eucalyptus, flowers and many others. GWSS spreads Pierce's Disease, a bacterial disease that kills grapevines and for which there is no known remedy or cure.
