Boracare is not labeled for carpenter bee control as the boracare must be ingested to affect the insect. Carpenter bees only tear away at the wood, they dont eat it like termites do so they normally will not be affected. Carpenter bees are normally less attracted to treated wood but even after sealing the wood, you could use a residual spray like Cyonara 9.7 to spray across the wood to kill them just from landing on the treated surface. Cyonara is also found in one of Carpenter Bee Kits here.
