• Adult beetle 4 – 7mm in length.
  • Red/brown in color.


  • Adult beetles usually appear in the summer months, but in heated premises they can be found throughout the year.
  • The larvae gradually reduce the infested timber, just leaving a thin veneer of wood on the surface.


  • Emerging adults make pin-hole sized openings 1 to 2 mm in size, often called ‘shot holes’.
  • Whole lifecycle is completed in about one year.
  • Primary pest of wood yards.
  • Given enough time, wood will be reduced to a mass of fine powder that crumbles to the touch, hence the name ‘powder post’.
