Insect Infestation

Adult beetles emerge from timber in the spring and summer. Very soon after mating, the female beetle lays approximately 30 eggs, often into cracks and crevices in the timber she has just vacated. Usually within a month, the eggs hatch and the young grubs begin burrowing into the timber. Here, they remain for between two and four years slowly eating and burrowing beneath the surface of the wood.

 

Eventually, the mature lava excavates a pupation chamber just beneath the surface of the wood. Following the pupation process, the adult beetle cuts a hole in the surface of the timber and emerges to start the process once more.

 

It is the appearance of new emergence holes and the dust (frass) that falls from them that often indicates the presence of an active infestation of woodworm.

 

Identify

  • Holes in the wood surface - the holes usually have a characteristically clean, sharp edge and need to be distinguished from holes made by nails and screws which leave a rounded edge. Floorboards will often show holes from fixing floor coverings.

 

  • Bore Dust ejected through holes.

  • Tunnels beneath surface.

  • Larvae found by probing.

  • Surface irregularities, usually bumps or corrugations.

Treatment

  • Assess the state of activity of any fungal infection or insect infestation found.

  • Establish by probing the extent of softening or powdering timbers.

  • Where the serious weakening of structural timbers is suspected, call in a structural engineer.

  • List all repairs required & recommended treatments. 

  • Assign priority to rectifying faults & repairing the building. ​

Death Watch Beetle

(Xestobium rufovillosum) The most damaging wood borer in old buildings, attacking hardwood and often found in timbers also suffering from fungal decay. Larger than the Common Furniture Beetle at 6 to 8mm long and greyish brown in colour. Its life cycle averages 5 to 6 years. The adult emerges from 4mm dia, round holes and is now known to be capable of flight. Eggs are laid in small clusters.
