What They Do

The European Grapevine Moth (EGVM) is an unwanted, invasive species of moth that feeds on virtually all varieties of wine and table grapes. The adult moths mate, producing caterpillars or worms that live and feed on grape flowers and fruit. Its small size of less than 3/8″ of an inch can make it difficult to spot, but it can cause serious damage to vineyards.

Areas where grape production thrives are particularly vulnerable to the devastating effects these moths can have. Controlling the spread of these pests can save time, money and jobs.

How it hurts

EGVM is an invasive pest. Any type of invasive pest presents a danger to local plants, crops and other species. They eat our food, wreck our gardens and throw our ecosystem off balance.

EGVM caterpillars directly attack grape flowers and fruit, making grapes unsellable in the fresh grape and wine grape market – ultimately causing an economic loss.

Whenever EGVM is detected, an agricultural quarantine is established within a five mile radius of the where the moth was discovered. Click here to see the areas that are currently quarantined.

Quarantines in your area can be both costly and time consuming. The quarantine restricts the movement of equipment, vine clippings and products for market. Once the moth is eradicated, the quarantine is lifted and operations can return to normal, but the process could take several years to complete.
