Box Tree Moth: Take action
If you have the pest there is a biological control spray called Dipel that is registered for control of Box Tree Moth. The active ingredient of the spray is safe to humans and pets and is the same as the one in BTK caterpillar killer sold at most retail garden centres. The same active ingredient is used by the City of Toronto to control Gypsy Moth. To kill the larvae, sprays need to be applied when larvae are feeding on leaves, typically from mid-May to mid-June and from mid-July to mid-August and early September.
