Woodworm treatment advice
12 March 2013
In the last week or so we have seen an increase in people contacting Timberwise for advice on treating woodworm – a sure sign that the woodworm season is upon us again! Traditionally the season for woodworm beetles to fly is in spring, roughly from March to May – this is when the adult beetle emerges from the timber to find a mate. To help understand woodworm we have compiled a few of the most common questions (along with the answers) we get asked by property owners about this seasonal pest!
What are woodworm?
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 types include Powder Post Beetle, Wood Boring Weevil, Death Watch Beetle and House Longhorn Beetle.
How do I know if I have woodworm?
– There are a few common signs that can identify a possible woodworm problem:
– You may see adult beetles emerging from their holes (commonly known as ‘exit holes’) these are small holes similar in size to holes in a dart board. These holes vary in size depending on the species of beetle.
– Beetles may be visible about the property.
– You may also come across what looks like fine powdery sawdust near the exit holes. This dust, known as ‘frass’, is made as a result of the beetle exiting the timber.
– Sometimes, although exit holes may not be visible, you may find ‘frass’ underneath wooden furniture – this also may suggest a woodworm problem.
This useful short film gives more useful information about woodworm in general:
Where can woodworm be found?
Woodworm can be found in any housing timbers, furniture or in wooden outbuildings. Infarct, anywhere in a property where there are exposed timbers. As timber accounts for anywhere up to 70% of the fabric of a house woodworm can cause serious problems.
How do woodworm get into a property?
Woodworm can gain access into any property through open doors and windows, air vents and even gaps in the eves.
Why is woodworm such a problem?
The woodworm larvae feed on the cellulose within the wood leaving behind a network of tunnels that can cause significant damage to the structure of the timber within the property. Dependent upon the level of woodworm infestation, it may result in the structural timbers of a property losing structural integrity if woodworm treatment is not carried out to put a stop to the life cycle of the beetles.
What is the life cycle of the woodworm?
The woodworm life cycle begins starts with the adult beetle looking for somewhere to leave its eggs. This could be on a door or window frame, the end of a timber beam or timbers within an attic space – anywhere where the timber is exposed. Here the female beetle will lay her eggs into 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 to start the whole process again.
What action should I take if I suspect a woodworm problem?
It is recommended that a professional survey is carried out to identify the woodworm infestation and locations and how urgent is the need for a solution. Only once the extent of the woodworm infestation is known can an appropriate course of woodworm treatment can be suggested. The surveyor will be able to identify the species that are causing the damage, as well as identify if the infestation is active or not.
