Castlewellin Gold Conifer Hedge: Weevils or Something Else?

Hedge of castlewellin gold conifers; one has lots of brown. Owner suspected weevils. Asked treatment and hedge maintenance.

The expert listed pests: bagworms (bags from foliage, pick off or spray malathion/Sevin) and cypress canker (kills tree, linked description). Weevils chew bark on twigs/branches/trunk. If brown with no bags, likely dead (bagworms rarely kill).

Diagnosis Steps

Check for bagworm bags.
Look for bark chewing (weevils).
Canker = fatal disease.
Brown + no bags = probably dead.
