The Box Tree Moth

In November 2018, the Canadian Food Inspection Agency (CFIA) confirmed the presence of Cydalima perspectalis (Box tree moth) on Buxus spp. (Boxwood trees or shrubs), in residential locations in Etobicoke, Ontario.

The Box tree moth feeds primarily on Boxwood foliage and bark. The CFIA is containing the pest while the regulatory status of the Box tree moth is being determined. This season, the CFIA will work with its partners to determine if this is an isolated event or frequent occurrence.

The CFIA, Landscape Ontario, Nursery growers, Garden centres, City of Toronto and provincial government agencies are working together to investigate this.

Boxwood is a viable landscape plant. There is an effective & safe biological control called BTk (Bacillus thuringiensis). It is a natural spore-forming bacterium and can be applied to protect the plants.

Q: Should I buy another type of shrub or small tree instead of Boxwood?
Boxwood is still a very viable landscape plant and there are tools available to help keep your Boxwood plants healthy.
