Fall Webworms in Trees: Cosmetic, Manageable

White webs on tree branches with black specks (frass) inside and yellowing leaves—fall webworm (Hyphantria cunea).

Management

• Prune out webs if reachable.
• Otherwise ignore—rarely harms tree health.
• Rake/destroy fallen leaves in winter (pupae overwinter).

Note

Not to be confused with eastern tent caterpillar (spring, branch crotches). Fall webworm = late summer/fall, branch tips.
