Signs of woodworm

Early woodworm identification is the key to stopping them before they cause more harm to your property.

You may not realise that you have a woodworm problem until the resulting damage becomes visible. If left untreated woodworm can seriously weaken timber - this may lead to structural failure of timbers.

Below we have explained the signs that could indicate that you have a woodworm problem.

Spotted Signs of Woodworm?

Any of these signs shown below could mean you have a woodworm infestation and a thorough inspection of your property should be carried out. Woodworm treatments by our trained technicians carry a 30 year guarantee so you can be sure all work conducted by us, will keep you and your property safe.

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.
