Tree Spray for Bagworms
The bagworm is one of the biggest threats to evergreen plants. If left unchecked, these pests can rapidly strip a tree of its leaves.
They will cause defoliation by chewing tiny holes into the leaves of deciduous plants. They both eat them, and then they build their protective “bags” out of plant leaves. What a cunning pest.
Your trees and shrubs may be infested with bagworms, which are unwelcome visitors, if you observe unusual yellowing or defoliation.

Understanding a Bagworm
Bagworm gets its name from the fact that the larvae resemble worms and emerge from bags.
The larvae carry these silk and plant-based pouches around for safety. Certain moth species’ larval stage, known as bagworms, harm both deciduous and evergreen trees.
The pest moths are characterized by their transparent wings, dense hair, and a dark brown or black coloration. In the fall, only the male bagworm moth is observed flying.
The females lay their eggs within cocoons that resemble bags.
When bagworms begin feeding, they are around 0.04″ (1 mm). But before they pupate, they can reach a maximum size of about 1 inch (2.5 cm).
There are over 1,350 different kinds of bagworms, according to research. The snailcase bagworm, Apterona helix, Astala edwardsi, O. townsendi, Oiketicus abbotii, and the evergreen bagworm are the most common.
Many regions of the world, including North America, Europe, Australia, and Asia, are home to these species.
