You need to find out what sort of borers you've got... in peach
trees, the typical borer is a clearwing moth, and most of the
growers use pheromone traps.  Insecticides are only effective
during the mating and egg-laying periods, as it's almost impossible
to get the insecticide to the insect after they've hatched and
moved under the bark.

Trees in the best of health are often much less affected by borers
than stressed trees, so a good part of the "cure" is usually 
maintaining good tree health.
