Woodworm Control - why we use wood preservatives

In the UK we are mainly concerned with woodworm treatment for Common Furniture Beetle, (Anobium punctatum, in Latin). We need to practice safe woodworm beetle treatment because of the long term damage that the woodworm larvae (grubs) cause in structural and decorative woodwork in domestic houses and commercial buildings.

Knowledge of the life cycle of the common furniture beetle (usually just called 'Woodworm' for short) is important when carrying out woodworm treatment because we cannot stop adult Woodworm beetles emerging using normal timber treatments, no matter which surface applied woodworm treatment product we use. To eventually cure woodworm we first need to break the 'egg laying cycle'.

Common furniture beetle starts life as an egg. These are laid on a bare, unpainted timber surface, or in cracks and crevices, end grain and down old emergence holes.

These larvae hatch, bore into the sap wood, where they cause most of the damage. The larvae feed on the wood and this 'worm' becomes larger for up to 5 years. At some stage the wood worm moves close to the surface and constructs a pupal chamber.

Between May and August the adult emerges from its pupal skin and chews its way out leaving the familiar 'woodworm holes'. When they cut their way out they are not actually feeding - the adult does not eat! When the adult beetles have emerged they mate and lay eggs, frequently down the old emergence holes and into the pupal chambers and tunnels. Sometimes both mating and egg laying can take place within the emergence hole itself.


How to stop Woodworm

Woodworm treatment is essential, if active woodworm is present, in order to prevent woodworm eggs from successfully boring into the timber and continuing the woodworm life cycle. If woodworm, or worse still Death Watch Beetle, (or even worse still House Longhorn Beetle) is allowed to continue to eat your wood, it will be structurally weakened by the multitude of internal tunnels and beetle flight escape holes. These exit holes are evidence of an attack of some type of woodworm, but the size of the exit hole is important in determining the beetle species and hence its life expectancy. Death watch Beetle has a much longer cycle (8 to 10 years) than Common Furniture Beetle (3 to 5 years), so woodworm treatment, as a woodworm killer, has to be adapted to suit the insect involved. Timber treatment is only part of the woodworm story. Dampness also plays an important part in woodworm attack, (woodworm prefer damp or wet timber) so timber treatment must take account of damp, its source and its control or elimination. Fortunately, Boron based products love moisture - they 'seek' the dampest parts of the wood, thus protecting the most vulnerable areas.

Consult our Qualified Woodworm Experts for safe, odour free Woodworm Treatment. We supply a Licensed Borax product as an Insecticide - very safe, no smell and permanent.
