Box Tree Moth

Cydalima perspectalis

The Box Tree Moth is an invasive pest that can quickly defoliate and destroy boxwood shrubs. Caterpillars feed aggressively on leaves and bark, often causing severe damage before homeowners realize there is a problem.

Early detection and timely treatment are critical to protecting valuable boxwoods and preventing long-term decline.

Signs of a Box Tree Moth infestation include:

  • Chewed or skeletonized leaves.

  • Webbing within the shrub.

  • Green caterpillars with black stripes and spots.

  • Rapid browning and thinning foliage.

  • Defoliation starting inside the shrub canopy.

If left untreated, continued feeding can weaken or kill boxwoods.

Healthy, mature boxwoods can take years to establish and may cost hundreds, or even thousands, of dollars to replace. Professional monitoring and timely treatments can help protect your landscape from the damage caused by Box Tree Moth.
