Wood boring insect infestation is commonly described as woodworm. However, this is actually just a term used to describe a number of different species of wood boring insects and not just one type insect.
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. In most cases treatment of Common Furniture Beetle is fairly straightforward. Any structurally-weakened timber should be removed and replaced with pre-treated timber
Other common woodworm species which may also be found in buildings 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.

There are a few common signs that can identify a possible woodworm problem:
Woodworm Beetles Emerging
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.
Bore Dust (Frass)
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.
Active or Inactive Infestation?
Active infestations will normally be identified by finding the above (Beetles emerging and frass), though this is not always evident and the activity might be out of sight.
It is always highly recommended that a qualified surveyor undertakes a survey when a woodworm problem is suspected. 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 (CSRT). Our surveyor has undertaken training and examinations to be able to identify all types of wood boring insects which may infest your home.
It should be noted that Inactive woodworm infestations do not require insecticidal treatments.

Can you tell the difference between the two?
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.
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.
On occasion structurally-weakened timber may need to be removed and replaced with pre-treated timber.

CK Walker Damp & Timbers team members are trained to apply timber treatments correctly and in a safe manner.
Two of our employees have succesfully passed an examination in the safe use of biocides and are now on the PCA Professional Users of Biocides Register for the Protection of Timber in Buildings.
This register provides a reference point for both suppliers and consumers who want to verify the professionalism of applicators,
We do charge a small fee for our PCA CSRT qualified surveyor to visit your property in Derbyshire or Nottingham. The fee covers the cost of the survey only.
Unlike some other companies, our surveyors are not commission based and are not required to “find” work on every visit.
We pride ourselves on our honest and thorough inspections.
If your woodworm problem is inactive, we will tell you and not advise any unnecessary chemical treatments.
