Answer: Bagworms are difficult to control because they are protected within their little bags. Most control measures should begin in the early spring when the larvae are actively feeding. At this time of year they are hiding in their protective bags.
You can use one of the following products for bagworm control now but I think you'll need to plan a second spray next spring when the larvae are actively feeding:
acephate (Orthene), bifenthrin (Talstar), carbaryl (Sevin), chlorpyrifos (Dursban), cyfluthrin (Tempo), diazinon, dimethoate (Cygon), malathion, nicotine sulfate, pyrethrum, permethrin (Pounce), rotenone and trichlorfon (Dylox, Proxol). Be sure to apply according to label directions.
