Look for the source of the infestation. It is frequently a damaged food package or one that has been opened and forgotten. You may see webbing or holes in the packages rather than the moths themselves. Seal and dispose of infested packages and wash shelf areas with soap and water to ensure removal of eggs and larvae. Use pheromone traps to trap adult males, checking them frequently.
Traps are effective for about three months.
Proper food sanitation and storage may prevent further infestations. They require long canes instead of spurs to produce good crops. Remove the old fruiting canes and leave the new canes in place. You will need only three or four canes on each vine. You are looking at borer larvae that tend to attack injured or stressed trees.
