Small, spindle-shaped bags hanging from cedars, arborvitae, or junipers are a sign of bagworm activity, and July is when the damage becomes most visible across the Chattanooga area. The larvae feed on foliage through summer, and a heavy infestation can strip a young evergreen bare by late season.
Caught early, bagworms are manageable and the tree typically recovers its foliage the following season. Left untreated for multiple years, repeated defoliation can kill a tree outright, since evergreens don't push new growth the way deciduous trees do.
The bags themselves are easy to miss since they resemble small pine cones or bits of debris at first glance, especially on established plantings where they blend into dense foliage. A closer look at any evergreen showing thin or brown patches is worth the time.
Tree Worx has served Chattanooga and the surrounding region for more than a decade, with a trained crew that identifies and treats seasonal pest issues like this one.
