The Long Term Effects of Untreated Woodworm


Woodworm is a common issue that can affect almost any household. Often, you only realise you have a problem months after the first infestation has occurred.

If you have noticed numerous meniscal holes appearing in timber within your home, such as in the skirting boards, this could be a sign of a woodworm infestation. The treatment of woodworm is not a particularly difficult process, depending on the type of infestation, but it can have potentially detrimental effects if action is not taken.

What Happens When Woodworm is Left Untreated

Insects crawl into the infested timber and lay their eggs. Once these eggs hatch, the larvae then feed off the timber, which usually has a moisture percentage of 20%, although it can be as low as 13%. Eventually, the larvae will dig through the timber once they have grown into adults, leaving tunnels in the material.

As well as small holes, another sign of woodworm is small pieces of dust left as a result of the insects scratching through the wood. This cycle will continue, and in greater numbers, unless woodworm is treated. It could even potentially spread throughout the building.

Potential Damage

If the problem is allowed to continue, it will soon manifest into a more widespread issue which can result in expensive repair costs. The timber weakens every time another tunnel is formed and this can cause serious problems, especially in structural materials. Damage to structural beams can be costly, and in serious cases, potentially result in having to leave the building while the problem is addressed.

Other concerns are the presence of the boring-insects which, while the most common species is not harmful (and is also the easiest to treat), can pose health risks. These are all important reasons why the immediate treatment of woodworm is essential.

Woodworm Treatment with Garratt’s Damp

At Garratt’s Damp, we have a team of highly skilled and experienced professionals on hand to deal with the infestation of woodworm. Usually, our team will implement a spray treatment to address the issue, requiring the building to be unoccupied for a period of up to one hour.

More severe cases may involve the introduction of a gel substance to the infected areas as part of the woodworm treatment. This could be due to the presence of a more invasive species, such as the Death Watch Beetle, which the spray would be ineffective on.
