3 questions:1. Carpenter bees/bore bees, what is the best way to prevent them from attacking your home. 2. Underneath the two upstairs bedrooms on all the counters and dressers is this dust. No termites no bug infestation just a saw dust covering. The ceiling is just a laid kinda dovetail floor. It only starts falling when kids romp around , is there something we can do to prevent this? 3. The cabin is white pine 17 year old with natural splitting in the wood,would it be good to seal all those
