How to Identify Signs of Woodworm

You may not realise that you have a woodworm problem until the resulting damage becomes visible, so early identification is key before they cause more harm. If left untreated woodworm can seriously weaken timber - this may lead to structural failure of timbers.

Not all woodworm species leave the same signs, however, if you find any of the following you could have a woodworm infestation:

    • Fresh exit holes in timber - Round or oval shaped with sharp edges, the holes will appear clean and fresh.
    • Tunnels in wood - (galleries) These are often hard to see.
    • Bore dust - (frass) Caused by emerging adult beetles, usually visible below the infested timber.
    • Weak & damaged floorboards - In extreme cases, a foot or chair leg going through the floor can indicate a more serious problem.
    • Crumbling wood - Around corners or edges to roof joists or floorboards.
    • Dead beetles - Usually found near the infested timber or around nearby windowsills.
    • Adult beetles - They emerge from timbers between May and October.
    • Eggs - These vary in size depending on the beetle, but all are difficult to spot with the naked eye.
    • Woodworm larvae - Usually a creamy-white colour and curved in shape.

If you have spotted any of these signs you could have a potential infestation; luckily our experienced surveyors are here to help. They will carry out a thorough inspection of your property to assess the extent of any problem and the type of woodworm involved.

What Does a Woodworm Look Like?

There are four stages of woodworm development, these are:

    1. Egg - Laid in cracks and crevices in wooden objects, floorboards and timbers by Adult beetles  
    2. Larva - When larvae hatch they immediately burrow through the timber, making it very unlikely they would be seen. Safely inside the wood they continue to tunnel and feed for several years.
    3. Pupa - As the larvae mature and increase in size, they bore towards the wood surface to pupate
    4. Adult beetle - emerge as adult beetles and look to mate.

Dealing with a Woodworm Infestation

Our professional surveyors will carry out a thorough inspection to assess the type of woodworm involved and any issues they are causing. They will also determine if the infestation is active, check for associated problems such as wood rot or damp and if any timbers need replacing. 

Based on this detailed evaluation they will then recommend any appropriate woodworm treatment. These woodworm treatments all carry a 30 year guarantee making sure the issue doesn't return anytime soon.
