Bagworms on Norway Spruce: Needles May Regrow on Tips; Prune Dead Wood Later

Current Status

Two branches brown, bagworms found, sprayed with Sevin. Tip needles will likely regrow; inner needles probably won't.

Don't Prune Yet

Wait until you're sure branches are dead (no bud break next spring). Premature pruning removes potential recovery points.

Bagworm Facts & Control

• One generation/year; eggs overwinter in bags.
• Hand-pick bags fall through spring.
• Bt spray late June (after hatch) for young larvae.
• Chemical options: Sevin, Orthene, Talstar, Dursban, etc.

Sevin worked; monitor for reinfestation next June.
