Timber Preservation Experts Halifax

There are many different types of woodworm and they all cause damage to any timber they choose to live in. Woodworm larvae bore holes in the wood in search of food; cellulose.Once adults, they create tunnels through the wood to find an exit, leaving small identifiable holes in the wood. Over time, the many tunnels and chambers created by the woodworm larvae leave the wood weak and damaged.


The first step to treatment is to fully establish the extent of the infestation. Our surveyor will be able to identify this. Once the extent of the infestation is known an appropriate woodworm treatment can be recommended.

Danford Brewer & Ives will first determine the species of woodworm causing the damage as different circumstances need different treatments. Depending on what they find, Danford Brewer & Ives can treat the woodworm with either a chemical spray, injection or surface paste.

For infestations that are not severe, normally only the surfaces of the timbers need to be treated to kill any emerging woodworm beetles and prevent them from mating and laying more eggs. This will protect the timber from further infestation by wood boring insects.

How to identify woodworm

The beetles that cause woodworm, and their larvae, are difficult to see. Therefore, identifying an active woodworm infestation means looking for the right signs.

Tell tale signs to identify woodworm include:

  • Small round holes in your woodwork, similar to the holes in a dart board.
  • Fine, powdery dust around these holes (this is known as frass).
  • Crumbly edges to boards and joists.
  • Adult beetles emerging from the holes or present around the house.
  • You may find frass at the back of or underneath furniture without seeing any visible holes.
  • Weak and damaged floorboards may indicate presence of active woodworm infestation.
If you think you may have woodworm infestation and would like to get it treated, please call Danford Brewer & Ives on 01422 229831 for a qualified survey.

Professional Woodworm Treatment

Depending on the extent of woodworm infestation, there are various ways to get rid of it and help prevent it happening in the future.

For minor outbreaks with surface damage, there are treatments such as specialist sprays that householders can carry out themselves. However they include chemicals, and so professional treatment may be preferable.

For more widespread and deeper damage the best option is to get professional woodworm treatment, especially if there are structural images associated with the damage. That involves applying gels or pastes to affected areas and in some cases cutting away parts of the timber to apply chemical treatments.

Woodworm Specialists

Woodworm specialists provide a valuable service in being able to pinpoint exactly what type of infestation you have. They will also determine what stage of the woodworm insect’s lifecycle your infestation represents.

That information is vital in ensuring you get the right treatment to rid your property of woodworm and help protect it against further infestation. A specialist’s approach includes a thorough on-site inspection to find out where the damage is and to look at the evidence for what type of insect has caused it.

The woodworm specialist will then recommend treatments specific to the extent and seriousness of the infestation and then carry out the treatment to make sure your property is free of woodworm.

How Effective is Woodworm Treatment?

To be effective woodworm treatment needs to treat the infestation that is the cause of the woodworm. If left untreated, woodworm can weaken timber in a property to the extent that the building’s structural integrity is at risk.

Because infestation is part of the lifecycle of wood-boring beetles, treatment concentrates on ending this lifecycle. It involves applying special insecticides and coatings to wooden surfaces that destroy the larvae of wood-boring beetles and prevent adults coming to the surface to mate.

This form of treatment is highly effective in preventing the spread of woodworm infestation. Depending on the degree of damage, some timber may then need replacing.

How Long Does Woodworm Treatment Take to Dry?

Woodworm treatments dry differently, depending on the type. Sometimes treatment requires the injection of high-strength, professional insecticide concentrates injected into the timber.

Other methods coat or spray specialist treatment onto bare wood surfaces. Because they are chemical-based, it may be preferable not to be in the property while it is being treated.

Many woodworm killer treatments, designed to treat wood, will require several coats and will take three days to dry. Other treatments can be dry in less time, depending on the extent of the infestation.

More intensive treatments come with a recommendation to vacate the property until around eight hours after application.
