The best product we recommend to use for wood boring insects is Boracare. Boracare will penetrate up to 4in into raw untreated wood. The active ingredient in Boracare is an inorganic salt and once in place will not decompose or volatilize out of the wood. Treatment is long lasting as long as the treated material is not exposed to rain, continuous water or ground contact.
