Wood Borers

Wood Borers or Wood-boring beetles which feed on wood and wood products cause extensive structural damage. The adults are known to emerge from larval feeding chambers through round, oblong, or D-shaped exit holes. Adults of some species also create holes into plaster, plastic and soft metals.Woodworm damage usually looks like little bullet holes that become visible on the surface of timber. Other signs also include traces of bore dust, resulting from the adult wood boring beetle emerging from the wood.

  • Woodworm is the collective name for the larval stage of certain wood boring beetles – it does not actually refer to specific species.
  • Like most other pests these wood borers are found to be seasonal in nature and the woodworm season usually runs from May to October.
  • Wood borers enjoy nibbling the wood in home furnishings. Attacks by wood borers are caused to timber internally and externally and is utilized as their food and as their home.
  • During its growth stage, the larva spends roughly about 3.5 to 4 years beneath the surface of wood. It slowly increases in size as it feeds on the timber. Once the larva has evolved into a beetle, it will bite its way through the surface of the timber, creating small holes.
  • These beetles are usually attracted to light and can often be found near windowsills, windows or loft hatches.
  • When it comes to preference of certain types of timber, wood borers can be picky and have preferences for certain types of wood. For example: The Deathwatch beetle has a strong preference for hardwood timbers like oak, ash and chestnut. An active infestation by this beetle nearly coincides with existing fungal decay problems, like dry rot.
  • Occurrence of wood borer problems can pose to be a serious concern if left untreated. In most extreme cases it could lead to the failure of the building structure.

Wood Borer beetles usually feed on hard wood.

Wood Borers lay their eggs in cracks of wood and are found across wooden areas like hardwood floors, timber, crates, antiques and other things made of hard wood.

Wood Borers usually make their way through wood by digging. Their attack on wooden surfaces permanently damages trees and things made from wood like furniture.


  • The best way to prevent a wood borer attack is through inspection of wood sources around the home.
  • All exposed wooden surfaces should be sealed with paint to avoid further damage./li>
