The Impacts of the Box Tree Moth on Boxwoods
Insect in the family Crambidae, introduced into Europe and a pest species of box (Buxus sp.)
The box tree moth is a highly destructive pest that is notorious for its devastating impact on boxwood plants. This invasive species is rapidly spreading across the continent posing a significant threat to ornamental gardens, hedges, and natural habitats where boxwood is cultivated.
Box Tree Moths feed exclusively on boxwoods. The young caterpillars feed on the undersides of leaves, while older caterpillars consume the entire leaf except for the midrib. They also create webbing throughout the branches which protects them from predators. Extensive feeding will quickly defoliate, damage, and even kill individual plants and entire plantings.
Proactive measures can slow the spread of the box tree moth.
Your best alternative is to contact your SavATree professional arborist for a detailed inspection and identification of the boxwood plants on your property. They will also recommend effective options for both treatment and prevention going forward.
