What is Woodworm?

Wood boring insect infestation is commonly described as woodworm


The holes that can be found in timber are caused by the larvae of beetles that feed on the wood.  The larger holes on the surface of the timber are formed when the adult beetle emerges.


The most common species of woodworm found in properties across the UK is the Common Furniture Beetle (Annobium Punctatum). The Common Furniture Beetle does not just attack furniture as their name suggests but can also attack building timbers such as joists, floorboards etc. Where an infestation is active a specialist insecticidal treatment may be required.


Other species which may also be found (East Midlands) are:


Wood Boring Weevils (Pentarthrum huttoni)  - They only attack rotten timber. By simply replacing the rotten wood, the infestation is eradicated.


Deathwatch Beetle (Xestobium rufuvillosum - usually confines itself to attacking Oak and Elm. Deathwatch Beetle infestations can require more extensive treatments than for Common Furniture Beetle infestations.


Powderpost Beetle (Lyctus brunneus) -Only attacks tropical hardwoods. Treatments are not always necessary as it is unlikely to thrive in the climate and will usually die out naturally. It is usually found in imported wooden furniture.

How to Identify Woodworm?


There are a few common signs that can identify a possible woodworm problem:


You may see adult beetles emerging from their holes or they may be visible about your property, often on window sills and on white surfaces. If possible, keep hold of a few of them in a small jar so our surveyor can identify them for you.


You may also come across what looks like fine powdery sawdust (Frass) near the exit holes. This is bore dust produced by the insect.


Sometimes, although exit holes may not be visible, you may find bore dust underneath timbers, on floors and on roof timbers.


We have years of experience in the assessment and identification of timber defects caused by woodworm.


All our woodworm surveys are carried out by our Certificated Surveyor of Remedial Treatments. Our surveyor has undertaken training and examinations to be able to identify all types of wood boring insects which may infest your home.


Our surveyor will assess all timbers which appear to be suffering from woodworm, any insects found and any other evidence such as frass deposits close by to timbers. All these will help identify the species of woodworm and whether the infestation is active or inactive.


Inactive woodworm infestations do not require insecticidal treatments.


The picture above shows - Common Furniture Beetle (Top) & a Biscuit Beetle (Bottom). Can you tell the difference?


Very similar in appearance and closely related, these insects can easily be confused and misidentified.


The Common Furniture Beetle can cause damage to important timbers and require a specialist treatment at a cost, whilst a Biscuit Beetle infestation will just require the infested food/materials to be removed.


This is why the correct identification is so important.


A CSRT Surveyor is trained to recognise the difference.

How Do You Treat Woodworm?

Correct identification of the insect is essential before any consideration can be given to whether treatment is needed.


Treatment for an active infestation of Common Furniture Beetles will normally involve a spray application of an insecticide or the application of a gel/paste. Our treatments are safe and effective.


All our quotation survey reports contain detailed specifications with important health and safety advice.


Any structurally-weakened timber will need to be removed and replaced with pre-treated timber.
