Well picked out Andy!
 
The common furniture beetle or common house borer (Anobium punctatum) is a woodboring beetle. In the larval stage it bores in wood and feeds upon it. Adult Anobium punctatum measure 2.7–4.5 mm in length. They have brown ellipsodial bodies with a pronotum resembling a monk''s cowl 
 

Life cycle

Adults do not feed; they just reproduce. The female lays her eggs into cracks in wood or inside old exit holes, if available. The eggs hatch after some three weeks, each producing a 1 mm long, creamy white, C-shaped larva. For three to four years the larvae bore semi-randomly through timber, following and eating the starchy part of the wood grain, and grow up to 7  mm. They come nearer to the wood surface when ready to pupate. They excavate small spaces just under the wood surface and take up to eight weeks to pupate. The adults then break through to the surface as adults, making a 1mm to 1.5 mm exit hole and spilling dust, the first visible signs of an infestation.


Pest control


Woodworm holes and burrows exposed in wooden floorboard

The first step in pest control is prevention, and for this it is helpful to understand that Anobium punctatum only attacks seasoned sapwood timber, not live or fresh wood. Also, it usually does not attack heartwood timbers. This is readily observed from infested structures, where one piece of timber may be heavily attacked but an adjacent one left virtually untouched according to whether it is made from the heartwood or the sapwood part of a tree trunk. Infestations are also usually a problem of old wooden houses built with untreated timbers. Some building regulations state that timbers with more than 25% sapwood may not be used, so that wood borer infections can not substantially weaken structures.

Infection, past or present, is diagnosed by small round exit holes of 1 to 1.5 mm diameter. Active infections feature the appearance of new exit holes and fine wood dust around the holes.

Because of the 3–4 year life cycle of Anobium punctatum, timber or timber products bought containing an A. punctatum infection may not manifest holes until years after the timber has been acquired. Infestation can be controlled by application of a residual insecticide (such as permethrin) to infected areas, by professional fumigation, or by replacing infected timber. Simple aerosol insecticide sprays will only kill the adult borer on the wing but not the burrowing larvae, which remain relatively protected inside infected timbers.

I'm impressed Marc.
 
On the treatment side I'm using Borax and keeping the moisture levels down. Thats the plan.
