Fall Webworms in Your Tree: Web Removal and When to Spray

Identification

Thick cobwebs with leaf nests on branches (N. GA) = Fall webworm. Caterpillars rarely threaten tree health; mostly unsightly.

Control Options

• Mechanical: Knock webs down with long pole (bamboo).
• Spray: Insecticide on nest + surrounding foliage.
• Burn (caution): Rags on pole, ignite — may harm tree.

Decision Guide

• Check webs: caterpillars still feeding? → treat.
• Caterpillars gone? → no action needed this year.
