Wood borers (Powder Post Beetles) are tiny beetles whose larva feed extensively on the wood. The adults while emerging make tiny pin size holes on the surface of wooden furniture or fixture. The fine yellowish colored powder starts appearing from these tiny holes. This indicates the destructive activity of borers deep inside the core of the wood as these are internal feeders. They feed on the cell contents of the sapwood. While feeding they make tunnels and pupate within the wood. Borers or Powder Post Beetles attack partially or fully seasoned wood with 10-15% moisture. (i.e almost dry condition).
The beetles are more active from March-April and become less active from November onwards.
There are several methods and options for control of wood borers . Selecting the best option depends on a number of factors, such as the Gravity of infestation, the location of infestation, and cost of treatment. Wood borers and Powder Post Beetles damage wood slowly so there is plenty of time to make a decision on control.
As a treatment wood preservative chemicals are required to be injected into these tiny exit holes with the help of syringe and larvae is targeted as only larvae is responsible for the damage to the wood. The wood surface is also applied with chemicals having petroleum base.
