The bags of bag worms can be removed from the tree by hand, sealed in a plastic bag and thrown away. This is best done before hatching begins in late May. After eggs hatch, the bag worms can be killed by spraying the tree with an insecticide aimed at lepidopteran insects. After late May or early June, destroying the bag does not kill all the bag worms since the worms are mobile and not fully contained to the bag. Bag worms on pine trees are camouflaged as small pine cones.
To determine the best way to deal with bag worms, understand their life cycle. Bag worms overwinter in their bags. When the larvae begin to hatch from May to early June, they eat the foliage of the pine tree. In August, the bag worms begin to build their bags for mating and laying eggs. The bags suffocate the tree and cause the areas they cover to brown and die.
