To the right you will see a section of bamboo floor with beetle exit holes marked with red circles. The large oblong circle also covers a difficult to see powderpost beetle frass. This was found by the owner of a Boston condo in a 6 unit 5 year old building. Traditionally, the treatment options were fumigation or removal of the infested wood in finished wood like this because surface treatments would not be effective due to the wood finish.
