When is the best time to apply Horticultural Oil?

Horticultural oil is an ideal remedy to deter overwintering pests. The best time to apply it to woody plants and shrubs is before the buds break and leaves open but you also want the little pests to be active, not hiding, so wait until temperatures warm up to above zero for at least 24 hours.
