Have Old House Borers infested your home?
The Old House Borer name is misleading as they are typically known to infest homes that are built in the past four to seven years. They feed on the wood and weaken timbers leaving behind a sawdust-like material as well as tunnels in the wood they bore into. They feed only on soft or Coniferous Woods such as pine and spruce. Often times the larva creates a sound similar to clicking nails and can be heard by the homeowner.

Will Old House Borers bite?
No, Old House Borers will not bite or harm humans or pets. They are a threat to the structure of a home or building.

Will Old House Borers damage my home or structure?
Yes, Old House Borers will damage timbers in a home. To avoid serious damage a pest management professional should be contacted at the first sign of infestation.

Recommendations for control:

Typically the damage is seen before the beetle. Contact a pest management professional if you suspect any type of wood infesting insect. Old House Borer damage looks like tunnels bore into wood and filled with a thin, powder dust.
