The Ag Commissioner's Office conducts an enhanced vine mealybug (VMB) trapping program of 25 traps per square mile.
Has vine mealybug (VMB) been found near you? Access data from our interactive map to find out. Each square represents a 25-acre area and are colored relative to the range of VMB males trapped. The map is searchable by APN, address or operator identification / permit number. Contact our office if you have questions about the map.
You can use our guide (PDF) to help navigate through the mapping program.
Agricultural Commissioner's staff releases bio control agents, Anagyrus wasps and Mealybug Destroyer, to help growers manage VMB populations. These releases are funded by Napa County Winegrape Pest and Disease Control District funds.
