OLD HOUSE BORER BEETLE DAMAGE

Front view of beetle damage This is the front view of wood damaged by Old House Borer Beetles. Notice the only visible evidence is the oval shaped hole.
Back (cut away) view of beetle damage This is what the Old House Borer beetle damage looks like beneath the surface. Notice the tunnels (called galleries) that the larval stage of the beetle creates as is feeds on the starch within the wood.

OLD HOUSE BORER

  • SHAPE OF EXIT HOLE: Oval
  • SIZE OF EXIT HOLE (inches): 1/4 to 3/8
  • WOOD TYPE: Softwoods
  • AGE OF WOOD: New and Old
  • FRASS: Very fine powder and tiny pellets, tightly packed
  • COMMENTS: The life cycle of this beetle can last from 3 to 12 years. Because this is such a long period of time, considerably damage can be done before the beetle is noticed, because of the few number of exit holes does not reflect actual damage inside the wood.
