Mr Inspector is a qualified building inspector in Melbourne with 12 years experience and carries out building and pest inspections for persons purchasing homes.
The above photograph shows powder post borer to a timber member in the roof frame and was detected during a building inspection in Melbourne.
This is often seen in conventional hard wood timber and misdiagnosed by some as Termite damage. We have often had to go to homes because someone like a cable installer has stated termite damage exists.
Powder post borer do minimal damage to timber and once they have consumed the sap wood they normally die. If a around 30% of a timber member has been damaged by borer it is preferable to have it replaced, especially if it is a structural load bearing timber member.
