An extremely pernicious pest, Bagworms attack all trees, both decidious and evergreen. The most common Bagworm targets of evergreens include: Pine, Spruce, Fir, Juniper, Hemlock, and Arborvitae. Deciduous trees include Sycamore, Sweetgum, Honeylocust and Black Locust.
Why should you be concerned?
Bagworms are spindle-shaped bags that can be seen hanging from evergreen branches or smaller brown spots on deciduous tree leaves. More mature larvae will strip evergreens of their needles and consume whole leaves of deciduous trees which are susceptible to their attacks. Unfortunately, noticing the presence of bagworms is usually difficult until they mature and deal extensive damage. Options for treatment can include destroying the bags or removing them manually. Chemical treatment is required for severe infestation in order to control the outbreak.
