This Bagworm Is A Silent Threat To Your Trees

Anyone who’s ever had an issue with an Evergreen Bagworm infestation knows the devastation they bring to trees. The poor trees become increasingly sparse in their pine needle distribution until they eventually lose them all and die. This is a sad end to the beautiful evergreen trees we all love. Thankfully, there are ways to save your trees if you know what to do.

Life Cycle Of The Evergreen Bagworm Effective management of the Evergreen Bagworm depends on knowledge of its life cycle. These moths' reproductive cycle starts when the female adult lays her eggs inside her own bag. The bag is then left hanging on the tree after she passes away. These eggs are dormant all winter long, hatching in late spring or early summer to produce tiny larvae. After hatching, the larvae leave the bag in search of an appropriate host tree. They start building their bags once they find a suitable location, using silk produced by special glands in their bodies. The bags start out small and unnoticeable, but as the larvae develop, they periodically emerge to replenish their casing with additional plant debris. These cases grow bigger and more obvious over time.
