Timber Treatment

Timber Treatment – Woodworm

Woodworm or wood boring beetles can be a problem. The first step is identifying the types of species and the appropriate treatment, if applicable.

Woodworm is a generic term that is used to commonly describe the larvae stage of all wood boring beetles. The most common beetle in the UK is known as the Common Furniture Beetle. However there are various other beetles which can make a nuisance of themselves. Other species, such as Death Watch Beetle (Xestobium rufovillosum), require a specialised treatment, whereas the Wood Boring Weevil (Euophryum confine) would require no chemical treatment. Our trained surveyors can undertake a survey and identify the appropriate treatment.

The active season for the wood boring beetles to emerge is normally between March and September which is when they are likely to be noticed in wood with active infestations.

What is the life cycle of the woodworm?

The woodworm life cycle starts with the adult beetle looking for somewhere to lay its eggs. This could be the end of a timber beam or timbers within an attic space – anywhere where the timber is exposed. The female beetle will lay her eggs on the timber. Once the eggs hatch, the larvae will burrow its way down into the wood where they can spend anything up to three years or more eating their way up and down the timber. Eventually the woodworm forms a pupal chamber; this is when they transform into an adult beetle. They eat their way out of the wood creating the woodworm hole to start the whole process again.

Identifying woodworm

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

  • You may see adult beetles emerging from their holes
  • Beetles may be visible about the property, often on window sills or under furniture
  • You may also come across what looks like fine powdery sawdust near the exit holes which is the boredust they produce
  • Sometimes, although exit holes may not be visible, you may find boredust underneath and on floor and roof timbers.

Woodworm can be found in any housing timbers, furniture or in wooden outbuildings. It can be found anywhere in a property where there are exposed timbers. As timber accounts for anywhere up to 70% of the fabric of a house, untreated woodworm can cause serious problems.


The Common Furniture Beetle (Anobium punctatum) is the most common woodworm requiring treatment. Typically spray treatments are undertaken, (in some cases paste, and in-situ pressure injection are also carried out). All of our timber treatment products have HSE certificates and most are English Nature approved for use in bat roosts. That means they are non-toxic to mammals, including humans.

When floor boards need to be lifted, we take care to limit any damage, leaving floors which are often exposed in good order.

Fibre glass, where present, can be moved and reinstated by our operatives if so required.
