The Q&A Archives: Cocoon-Shaped Objects on Tree

Question: I have some small cocoon-shaped objects on my tree. The trees are now turning brown. What can I treat them with?

Answer: Bagworms are caterpillars that make distinctive spindle-shaped bags on a variety of trees and shrubs throughout the U.S. They attack both deciduous trees and evergreens, but are especially damaging to juniper, spruce, pine and cedar. Large populations of bagworms can strip plants of their foliage and eventually cause them to die. Infestations often go unnoticed because people mistake the protective bags for pinecones or other plant structures. Sevin carries a variety of products to treat the problem, available at The Home Depot.
