Glassy-winged sharpshooters spread Pierce’s disease, which is a bacterial infection that can often be fatal to grapevines, the Napa County Agricultural Commissioner’s Office said. They can also damage citrus, almond and residential backyard plants.

The pest was detected on shipments of grapevines and citrus plants from Burchell Nursery, Inc. in Fresno County to Costco store locations in Napa, Solano, Sonoma and Marin counties, according to officials. The affected plants were received at Costco stores between April 21 and Tuesday, May 26.

“Costco is directly contacting members who purchased plants within the timeframe and has been a cooperative partner with all County Ag Commissioners,” Napa County officials wrote.
