Pick up and dispose of overripe or rotting berries rather than leaving them around the plants.
Keep the area clean. Good garden sanitation can reduce breeding opportunities.
Monitor your plants. Regularly check ripening fruit for softness, discoloration, or other signs of infestation.
These measures are recommended by extension specialists as practical ways to manage spotted wing drosophila around home gardens.

In many cases, the culprit is a tiny fruit fly whose larvae develop inside soft fruit. The best response is simple: inspect your berries, wash sound fruit thoroughly, and discard berries that are visibly infested or deteriorating.
So the next time you see a tiny white “worm” inside a raspberry or strawberry, you’ll know what may have caused it—and why it can be so difficult to spot
