Small brown, cone-shaped bags hanging in arborvitae and junipers are bagworms, and they're active across Frederick County this month, feeding on needles from inside a protective casing that makes them easy to overlook at a glance.
Because each caterpillar stays hidden inside its own protective bag while it feeds, infestations are genuinely easy to miss until a whole section of the plant has already turned brown and thin. Evergreens are especially vulnerable since they don't regrow needles as fast as deciduous trees.
Watts Tree Experts inspects arborvitae, junipers, and other evergreens for bagworm activity and can recommend treatment before an infestation spreads through an entire hedge or screen planting, saving the years of growth it took a privacy screen to fill in.
If you've noticed small bags hanging in your evergreens, it's worth having them checked soon, before the damage spreads any further into the rest of the planting.
