Imigold will not work on bagworms. For bag worms you must you a spray like Fertilome Borer, Bagworm and Tent Caterpillar spray on the foliage of the plant. No systemic soil drench or injection product will work on bag worms so spraying down all the surfaces they are on of the tree/plant is the only way to control them. You can apply the spray at the rate of 2 ounces per gallon of water.
