Safe removal of boxwood affected by box tree moth
Box tree moth (Cydalima perspectalis) is an invasive pest found in urban landscapes within the Greater Toronto Area that selectively feeds on boxwood shrubs. High populations of box tree moth caterpillar may defoliate boxwood plants; in some severe cases this can result in plant dieback. It may be necessary to remove or trim the shrub.
Effective removal and disposal of infested plants is crucial to slowing the spread of box tree moth. Please follow the measures below to help prevent the spread of this pest to locations where it is not present:
- Place the infested shrub or branch clippings in a black plastic garbage bag and secure the bag to ensure it is closed tightly.
- Place the bag outside in direct sunlight for 48-hours.
- After 48 hours, larvae should be dead and the plant materials can safely be added to yard waste bins.

- July 15 to Aug. 15
