What are the best products and time schedule to treat arbor vitae trees infected with Bag worms?
We recommend using Talstar P for the treatment of bagworms. You can learn more about how to eliminate bagworms by reading our article Bagworm Control. Applications should start in April and continue monthly through June for bagworm control. Treatments should start around the time when the larva move out of the mother's bag and before they make their own bags. Be sure foliage is sprayed thoroughly to the point of runoff to achieve adequate coverage
