Can I use Boracare on logs that have already been stained?
I have a 9 year old Douglas Fir log home near Albany, NY and started noticing small flying insects boring many small round holes on all sides of the house. The logs have only been stained and not UV or water repellent treated yet so I'm hoping Boracare can be spayed now to soak in past the stain and then once dried I'll apply a special log wood sealant...
Unfortunately BoraCare will not penetrate through stain either. You would have to sand the surface stain off of the wood, pressure wash it off, or drill holes into the infested area and inject Bora-Care into the center of the wood. Those would be the only options.
