Don’t let EGVM ride with you. You can help stop the spread of EGVM by making sure you don’t transport grapes, nursery stock or green waste to or from a quarantined area.
If you have grapevines in your back yard or on your property, be on the lookout for EGVM. If you think you see signs of EGVM, please contact your County Agricultural Commissioner immediately. Also be sure to report any abandoned vineyards, which can serve as sanctuary for these pests.

Non-commercial and residential grape growers
If EGVM was found within 500 meters of your property, it is strongly recommended that you remove blooms and/or fruit from the grapevines. Even if EGVM has not been discovered in your area, this action works as a preemptive strike and is the preferred method for stopping the pest. Be cautious to dispose of the clippings carefully by keeping them in a sealed container or bag until they can be picked up by your local yard waste service.If you are within 500 meters of an EGVM finding and cannot or do not wish to remove blooms or fruit other treatment options are available. Please contact your County Ag Commissioner for recommended treatment materials and application instructions.
Home winemakers in a quarantined area face the same restrictions as commercial growers regarding the movement and treatment of grapes, equipment and green waste. A compliance agreement is required if you plan to purchase and transport grapes from a quarantined area. Grapes must be covered until they are used and the winemaking leftovers must be covered or placed in a sealed bag for disposal.Please contact your County Ag Commissioner for more information on compliance agreements.
Vineyard workers/owners of grape production equipment
If you are working in an EGVM quarantined area, make sure to clean all equipment and tools before moving into a new area. Make sure that green waste is covered or placed in a sealed bag until it can be removed.
Now that you’re an expert on EGVM, we would appreciate your help in sharing your newfound knowledge. Tell your friends, your families, your neighbors and, particularly, anyone you know who works in the grape industry. By spreading awareness, you could help prevent the devastating effects of EGVM in your area.
What to look for
Because the moth can be so difficult to see, there are other symptoms of an infestation to look for. Early in the season, caterpillars feed on flowers and buds. Later in the season, they feed on the individual grapes and live inside them. This causes mold to develop on wounds to the skin of the grape. The fruit turns brown and rots.
It is important to look for these warning signs, since the individual moths may be difficult to spot. They are difficult to see because they spend most of their time inside of the actual grape.
