A is for… Anobium punctatum – The Common Furniture Beetle (Woodworm)

In this episode of The A-Z of Damp from Atlantis Damp & Timber Proofing Specialists, A is for…… Anobium punctatum – The Common Furniture Beetle (woodworm).

Atlantis Damp Proofing & Timber Specialists recently sent our timber specialist surveyor to survey a local property near Cuddington in Cheshire. A grand old coach house with the potential to be a dream home, with parts of the property built as early as 1810. All of the rooms were stripped back to the bare brick to allow for a high quality finish and it was clear to see that the owners were not cutting any corners whilst developing their dream home.

How to Diagnose Woodworm

Once the bare brick and roof timbers were exposed the owners asked Atlantis Damp Proofing & Timber Specialists to come and survey the timbers and offer their expert opinion.

Atlantis can find and then solve your woodworm problemsOur surveyor was able to diagnose the infection by small round exit holes of 1 to 1.5 mm diameter present on some of the roof timbers. He used his expert knowledge to identify if the Common Furniture Beetle (CFB ) was active.

CFB has a breeding season just like many creatures you are familiar with. This is the ‘flight season’ when mature larvae pupate below the surface of your timbers and emerge as beetles to mate and lay eggs. Summer is the season of love, but the period is a bit flexible in houses. This is due to heating and such, so you may get fresh holes anytime between about March, through to September. New holes you see are usually part filled with ‘frass’. Frass is the excrement of woodworm.

Our surveyor also looked for signs such as:

  • any adult carcasses,
  • fresh ejected frass,
  • number and density of the flight holes

After looking for these signs, our surveyor then assessed the risk of leaving the infestation as opposed to treating it. Our examination of the exit holes and the fine bore dust around the holes suggested an active infestation. In addition, we saw that two of the smaller cross beams in the bathroom area were heavily infested and significantly weakened.

Finally, we prepared a detail report containing our diagnosis and recommendations to the Client. Then they confirmed that they were happy to proceed with the work.

What should I look out for in my home?

There are several ways that you can spot and identify a woodworm infestation in your property and these are the signs that our surveyor looked for in the case study above:

  • Small round exit holes– tiny holes may be noticeable in timber suggesting an active woodworm infestation is present. These flight holes are created when the larvae pupate and hatch into adult beetles, boring their way to the surface of the timber to mate and reproduce.
  • Fine, powdery dust– woodworm also often leave a trail of bore-dust, known as frass. This will be noticeable near exit holes as the beetles emerge from the wood. The presence of frass would suggest that the woodworm infestation is active and treatment is necessary.
  • Movement in floorboards / damaged timbers – if you have noticed furniture, flooring or structural timber is noticeably weaker it could be a sign of woodworm.
  • Beetle activity outside of timber– If you notice beetles emerging from timbers, or dead beetles close to the proximity of holes then you more than likely have a woodworm infestation.

How can I tell if an infestation is active or historical?

It isn’t always easy. You could fill any holes with a shoe polish, wait for the emergence season in spring and then reassess the holes to see if the polish s till there. If it’s gone, your infestation is active. Alternatively, you could tape some paper to the beam or timber, again await for the springtime emergence season and then look to see if the frass mentioned above has collected in the paper.

D is for…… Diagnosing Dry Rot

In this episode of The A-Z of Damp from Atlantis Damp & Timber Proofing Specialists, D is for…… Dry Rot.

Dry-rot fungus is often thought of as a building cancer, rampaging through buildings and rapidly destroying any timber in its path! Dry rot can lurk behind the scenes in areas of a property. Unseen, undetected and left untreated dry rot can cause vast amounts of damage to timbers.

Dry Rot Specialists

Our Cheshire based dry rot specialist, was called out to a property in Warrington after the home-owner had noticed what they believed to be a form of wood decay growing in her wood lined cupboard under her kitchen stairs. From looking at the characteristics of the decay, it was clear to our expert that there was definitely a dry rot outbreak present. However, it wasn’t until our surveyor removed an air brick adjacent to the under stair cupboard that the full extent of the dry rot outbreak was revealed.

sort out any dry rot problems with Atlantis NorthwichBehind the air brick, lay a large fruiting body otherwise known as a sporophore. These fruiting bodies can appear in an array of shapes and sizes dependent on the conditions present. Most of these round-shaped fruiting bodies are a rusty deep red colour (the spores). The outer parts of this growth being a much lighter white colour. Other signs may have included strands – (fibres, that look like small plant roots, dirty off-white to silver grey in colour), or Sheets – called Mycelium – (looks like a dirty off-white skin, can be tinged with yellow. These can be very wet and occasionally found as billowing cushions of off-white growths).

Identifying the Cause of Dry Rot

Before any treatments can be made to the affected area it is always important to identify the cause of the dry rot. In this case, it was apparent that the lack of ventilation caused by the use of hardwood to block the air brick was a major contributing factor to the growth of dry rot. This, combined with surrounding damp cavity wall insulation had caused moisture to linger providing an ideal environment for dry rot spores to germinate. Wood rot germinates from spores that have perfect living conditions for growth – such as damp, humid areas with a plentiful food source of cellulose or lignin within timber.
