Bagworms are mostly found on evergreen trees (Leyland Cypress, Arborvitae, Juniper, Cedar, etc.) and will do deadly damage to these trees. These caterpillars create a silk and evergreen foliage cocoon that can easily blend into a tree. Bagworms hatch around the end of May or beginning of June (depending on the region’s growing degree days) and extend their feeding season over a 6 to 8-week time frame.
Bagworms start out as a small worm and bag called a “dunce cap”. As they continue to feed, they and their bags get bigger. If left uncontrolled, they can not only wipe out an entire tree, but an entire row of trees. Control for this pest can be provided by spraying a systemic insecticide to the tree which the bagworms ingest causing them to eventually decease. In addition, handpicking what you can off your tree can help prevent further reproduction of the pest.
