right in the middle where the beam meets the ceiling you can see an oblong hole in the ceiling with dust coming down about 2/3 of the distance of the beam.
What is causing holes and sawdust on ceiling rafter beams?
I have noticed more problems on one of the wooden beams along the ceiling in my basement as pictured. There are three equally spaced holes in the top of a vertically placed beam on my basement ceiling that appears to have sawdust coming from it. My immediate thought was termites but the symmetrical nature of the holes makes me believe it could also be something else. Sorry the photos are not better. If anyone has any comments, I would appreciate hearing them. Thank you. Mike PS The oblong shaped holes are actually in the ceiling and not on the beams
here you can see in the middle one of the holes with sawdust coming down from it. Not so clear is a similar hole on the left with dust coming down.
here you can see all three holes spaced equally apart with sawdust coming down from them. the holes are in the ceiling with the dust coming down the sides of the beam.
