Adult beetles enter properties – through windows/doors, vents, etc.,  looking for a place to lay their eggs – in cracks and crevices of wooden objects, floorboards and timbers.

When the Larvae hatch, they feed on the wood, this being their food source.   The Larvae continues to feed and tunnel for several years increasing in size as they bore towards the surface.   They emerge as ‘Adults’ – this is the ‘Flight holes’ that you see in the timber.

The Adults can sometimes return to the same area/timber to lay their own eggs – therefore the cycle then starts again.


The Four Stages of Woodworm:





•Adult Beetle


WOODWORM is also referred to as Common Furniture Beetle (anobium punctatum)




•Exit holes in timber (small holes)

•Wood powder/dust (also known as Frass)

•Dead Beetles or Adults beetles in area

•Crumbling wood/weakened wood


The Adult Beetles fly out between the months of May and October. If left, and untreated woodworm can seriously weaken timber and cause Structural Timber Damage.

West Highland Timber Preservation



Wood Boring Weevil (Pentarthum huttoni) is the insect that is most commonly  mistaken for Common Furniture Beetle.

This Beetle lives in partially decayed timbers in damp conditions, and can be found  in areas such as basements, cupboards under stairs, damp floors and poorly ventilated areas.



No Chemical Treatment is usually required, the source of the Dampness has to be removed, and remove the infected timber.   Wood-Boring Weevil do not infest dry timber.



Our Remedial Surveyor will arrange to carry out a thorough Inspection of all accessible Timbers and assess the extent of the Attack, and  he will also check to see if the Infestation is still Active, and  check for any problems that could be associated to the Attack, such as rot or dampness, and if timbers require replacing. Once the Survey has been completed, he will make a note of his recommendations and Treatments.
