The feeding and boring done by the larvae damages the phloem and spreads a fungus that was introduced when the adult female laid the eggs. The best action for the homeowner is to clean up and remove any downed trees or branches. Don't just throw them on a pile out back, they'll still act as an attractant for the beetles. Have them hauled off. Any dead or dying pines should be removed, also.
Sanitation is the key for the homeowner.
