Woodworm Control


The generic term ‘woodworm’ relates to the larval stage of many species of wood boring insect.

The most common example found in UK homes is the Common Furniture Beetle (Anobium Punctatum), which is estimated to be responsible for 75% of all timber damage in the UK.



  • The Common Furniture Beetle leaves 1-2mm holes in the surface of the timbers it attacks and also small piles of dust (frass)
  • Identification of the specific wood attacking insect can prove difficult due to the many species involved and the numerous types of timber affected – there are many similarities. A visit from a surveyor is always recommended to confirm the presence of the insect
  • Another common wood attacking insect is the Death Watch Beetle (Xestobium Rufovillosum)



  • The initial attack is made when an adult Common Furniture Beetle lays its eggs in small cracks on the surface of the timber
  • The resulting larvae that hatch will then bore into the wood in search of cellulose to feed on - this is the longest stage for this insect and can last 3-4 years
  • The larvae will eventually create a chamber near the surface of the wood in which it pupates for approximately 8 weeks before changing to an adult
  • The new adult will tunnel through the short remaining distance as it attempts to exit the wood, creating a small but visible flight hole. This results in frass, a fine and gritty powder of gnawed timber
  • The liberated adult will then seek to mate and the process will re-occur; this stage is typical between May and September
  • The tunnels and chambers will eventually lead to a weakening of the timber. If left unchecked, replacement may even be required

The cycle and periods of insect attack vary with species.


The Solution:

The best methods of treating woodworm will vary according to the particular insect in question. Fortunately, the most common infestation is one of the easiest to treat.


Spray Treatment:

Timbers attacked by the Common Furniture Beetle are often treated with a chemical spray. This permits access to areas that are difficult to access with brush applications. The treatments we offer only require a one hour no entry period post-treatment, offering minimum inconvenience.


Gel Treatments:

For more invasive species such as the Death Watch Beetle, a gel treatment is better suited. Paste injections and a surface application of gel will ensure a full treatment.

Garratt’s offers a full survey and treatment for woodworm. We would always recommend a free inspection is booked with one of our professional surveyors to ensure the right diagnosis and best treatment is chosen to treat your specific timber issues.
