I would apply the spray to susceptible timber throughout the area where the borer was active, mainly because their long life cycle within the timber (i.e. from when the larvae first emerge from the egg until when the adult emerges from an exit hole) means that extensive damage can occur. Sound timber now may not be in 3-4 years time.
