This will be the third year I am trying to eliminate bagworm's on my Arborvitae. Desperate for something to work. Used Neem Oil last year and burned the plant due to heat and continued treatment. They were somewhat controlled but left alot of bags which I have been hand harvesting.
You will use 0.4-0.8 oz. of Permethrin SFR per gallon of water every 21 days as necessary for bagworm control. Keep in mind that this needs to be applied before the bags have formed. If the bags have already formed, there is little you can do for control other than to physically remove them.
