The beams have to be drilled to create "pockets" in which Bora Care or a similar chemical can be injected. Typically, a 1/2' hole drilled every 6-8" along the length of the beam sufficient. The holes need to be at least to the center of the beam. The holes are then filled with liquid chemical with a syringe or turkey baster type applicator. Generall 2-3 applications are recommended to be sure that the chemical soaks through. This can be done at long intervals if necessary, months apart. After all signs of beetle activity stop, fill the holes with putty.
The only other option is to sand the finish off the beam and treat the bare wood. Bora Care only penetrates about 2" so a thick beam may not be treatable using a surface spray. Drilling pocket holes may be the only answer.
