Peach Tree Plum Curculio: The Cause of Oozing Sap and Worms

The Culprit

Plum curculio, a small snout beetle, overwinters in debris and emerges in spring. Females lay eggs in tiny fruit wounds, causing clear sap to ooze. Larvae feed inside, creating "worms." They're active at night, so you rarely see them.

Control

• Organic control is nearly impossible.
• Use a "home orchard spray" per label directions—avoid spraying during bloom to protect pollinators.
• Destroy all blemished fruit; don't leave drops on the ground.
