The Napa County Agricultural Commissioner's Office is concerned about the introduction of new, exotic and destructive organisms. A significant exotic pest infestation could affect everyone in the county, through the loss of markets for farm products, increased pesticide usage and production costs.
A comprehensive insect trapping program is facilitated by staff. Additionally, we conduct inspections of plants entering the county from throughout the state and across the country.

On Tuesday, June 4, the Napa County approved the new Accepted Customs and Standards for Propane Cannons. These new standards specify the "Proper and Accepted Customs and Standards for Operations of Propane Cannons and other Audible Frightening Devices Used Within Napa County Agricultural Lands".
The sentinel trapping program targets pests not known to occur in the United States, or which may occur in a very limited distribution. These specific pests have not been found in Napa County, but their introduction would pose a serious threat to the wine grape industry. Early detection of significant pests could reduce crop losses and treatment costs. It could also help prevent the spread of these pests to additional counties, states or countries, minimizing the overall impact on trade and market distribution
The wine grape pests that are being trapped for in our sentinel program include: Grape Berry Moth, European Grape Berry Moth, Grape Tortrix Moth, Honeydew Moth, and Olive Moth. We currently have approximately 1200 sentinel traps placed throughout Napa County. This program is funded by the Napa County Winegrape Pest and Disease Control District and the County of Napa.
The goal of the general trapping program is to detect the introduction of very specific pests within Napa County through the placement of traps using pheromones, food lures or visual attractors. Our insect trapping program routinely monitors for European Grapevine Moth, Glassy-winged Sharpshooter, Vine Mealybug, exotic fruit flies, Gypsy Moth, Japanese Beetle, and Western Grapeleaf Skeletonizer (PDF). Learn more via the University of California Pest Management Guidelines. For details on these pests to go the CDFA Pests and Disease page.
