WDI/WDO signs?

Found on attic rafters and basment joists. No significant damage just these holes/tubes in random spots. Early 1900’s house in great shape.

Looks like (2nd photo) they are from dirt-daibers

Could be Cerambycid beatles. They infest before the lumber is cut and do not reinfest. They are probably not a problem.
