Also, how often should I spray to control the bag worms?
Bifen XTS is mixed at 0.03 to 0.13 fl oz per gallon of water for bag worms. You can apply once a month. Keep in mind that once the bagworms have formed their bag, there is little you can do for control other than to physically remove them. Applications should typically start in April and continue monthly through June. Be sure foliage is sprayed thoroughly to the point of runoff to achieve adequate coverage.
