In early fall, the mature larvae attach their bags to twigs and transform into the pupa or resting stage before becoming an adult.
Where do sack worms come from?

Once nestled in this self-made bag, a female Bagworm can lay between 500 to 1,000 eggs—meaning your Bagworm problem will multiply into a major infestation if left unchecked. Each egg will hatch into another Bagworm that will be ready to rip into any foliage nearby.
What animals eat bagworms?
Bagworms are commonly parasitized by ichneumonid wasps, notably Itoplectis conquisitor. Predators include vespid wasps and hornets. Woodpeckers and sapsuckers can feed on the larva from their cases.
Do birds eat bag worms?
There are also three common birdfeeder birds that are known to scavenge bagworm eggs from twigs and branches during the winter months: chickadees, nuthatches, and titmice. So keeping that birdfeeder going through the winter months might have some secondary benefits in addition to being something fun to watch.
How can you tell if bagworms are dead?

What does a bagworm caterpillar look like?
Bagworms look like shiny dark or black caterpillars that grow up to 1” (2.5 cm) long. The black worm-like insects have a segmented body and an amber-colored, translucent head.

How do bag worms spread?
Bagworms move about freely to feed, and they carry their bags with them. The bags gradually enlarge as they feed during the summer to house the growing caterpillar. They spread from tree to tree by ballooning (they spin a fine web and use wind currents to infest nearby trees).
Where do bagworms go in the winter?
Bagworm overwinters as eggs in the female bag. They hatch in late spring, exiting the bottom of the bag. The tiny caterpillars climb to the top of the tree where they each spin out a silk strand 1 to 3 feet long. This catches in the wind and carries the tiny larva wherever the wind blows.
Do bagworms bite?
