Unlike many other pest control companies that just use surface sprays, we we can also offer one of the best water-based high pressure woodworm treatment systems currently available on the market .

Although not all cases of woodworm problem require high pressure woodworm treatment, this kind of treatment is  really important where there is a strong possibility of woodworm infesting your roof beams. If this is the case, the treatment is designed to allow the fluid to penetrate as deep as possible to kill the insects and prevent further structural damage to your home. Spraying the surface unfortunately will not suffice.


What is woodworm?

is the general term given to the infestation of timber and wooden items by wood-boring insects.
Woodworm isn’t actually a worm – in fact, they are insects and their larvae that bore into wood, causing damage to furniture, floors and a building’s structure.

Woodworm refers to the larvae of any wood-boring beetle, rather than one particular species.

In Ireland, the most common woodworms

  • Common Furniture Beetle (Anobium punctatum),
  • Deathwatch Beetle (Xestobium rufuvillosum),
  • House Longhorn Beetle (Hylotrupes bajulus)
  • Powderpost Beetle (Lyctus brunneus)



How can I tell that my house has woodworm problem?

Signs of woodworm infestation

  • Burrow holes: in floorboards, timber beams, windows, door frames etc.
  • Dust: white or yellowish powder can often be found around these holes.
  • Damaged wood: The longer the woodworm goes untreated the more severe the damage. This can lead to structural issues in your home.
  • Tunnels: When the larvae burrows into the wood it creates tunnels which weaken the structure of the wood

You’re unlikely to see a wood boring insect – and certainly not the worm-like larvae – in your home, but you can certainly see the results – tiny holes in timber caused by the boring as the adult beetles emerge from the wood.


How Did They Get In?

Woodworm is often brought into the home unwittingly in second hand furniture or reclaimed timber. However, the beetles can also fly into the house from outside.

Where Do Woodworm Live?

Woodworm is often found  in household attics, eating away at your roof beams. An unchecked woodworm infestation can result in weakening of timbers and the whole structure of your house .

The Common Furniture beetle, the most common wood worm, likes damp wood and plywood. You’ll find it in damp floorboards, old furniture and loft rafters.

Professional Woodworm Treatment – What Is Involved?

Woodworm Infestation


There are a number of species of woodworm beetles and the precise method of treatment will depend on which species is attacking the timber.

Woodworm can be treated using a chemical insecticide which will be applied to the affected area to prevent further infestations. However, applying the treatment requires a lot of preparatory work.

All timbers must be cleaned down first and any roof insulation material will have to be removed temporarily so that you can get at the joists to work on them. Also this avoids the fire-risk of insulation becoming impregnated with the fluid or small polystyrene granules dissolving together.

You need to cover electric cables and the cold water storage tank. Floorboards must be lifted to get at the undersides and the joists. Depending on the situation, your furniture may also have to be dismantled and treated.


Not all wood worm needs specialised, high-pressure treatment, however some types of wood worm burrow deep, so they can cause extensive damage and require more than just surface spray. In those cases, to treat the wood effectively and prevent the problem from re-occurring, you need professional equipment which can inject the treatment deep into the timber.

Do you need Insulation also? We can install insulation on the same day as we treat for your woodworm.
