woodworm treatment

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

Although you may have a seemingly small visible woodworm infestation, we use the high-pressured woodworm treatment to ensure we get the full infestation and give you a guarantee of a long-term solution and to prevent further structural damage to your home or business.

What is Woodworm?

Woodworm is the general term given to the infestation of timber and wooden items by wood-boring insects. It 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 are:

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

Can Woodworms Bite People?

No. We’ve written an article about this, if you’d like more detail, though.

How can I tell that my house has a 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 burrow into the wood it creates tunnels that 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.

What a woodworm infestation looks like 

How did they get in?

Woodworm is often brought into the home unwittingly in second-hand furniture or reclaimed timber, the beetles can also fly into the house from outside. We can expect to see more woodworm infestations in the future due to climate change. They’re also more active in a mild autumn.

Where will you find woodworm?

Woodworm is often found in household attics, eating away at your roof beams. An unchecked woodworm infestation can result in the weakening of timbers and the whole structure of your house. The common furniture beetle, the most common woodworm, likes damp wood and plywood. You’ll find it in damp floorboards, old furniture and loft rafters.

If you notice any signs of woodworm in your home, call us immediately. We will treat woodworm infested areas and tell you what to do to prevent the problem from re-occurring.

Our IPCA qualified technicians will:

Can I treat this problem myself?

There are products that are available from DIY stores, and care should be taken when using as instructed. Woodworm is best treated by a trained professional who can guarantee you won’t have a reinfestation. 

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. Small infestations of 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.

Some woodworm infestations need specialised, high-pressure treatment as some types of woodworm burrow deep. 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 to inject the treatment deep into the timber.

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