Signs of woodworm

Spotting the signs of a woodworm infestation early will help you prevent these pests causing any serious damage to the property. If allowed to continue untreated however, severe cases of woodworm will lead to weakened timbers that can ultimately compromise the integrity of the building.  

Thankfully, there are a variety of ways to identify woodworm and begin the necessary treatment to eradicate the problem. If you suspect you have a woodworm in your home then get in touch by sending in an online enquiry or continue reading to see if you recognise any of the signs of woodworm or woodworm larvae.

How to identify woodworm and woodworm larvae

The following guide will talk you through the signs of woodworm infestations in order to help you identify if you have a current and active woodworm population in your property. After our hints and tips you will see a gallery of woodworm infestation pictures to help you cross reference.

If you do recognise these signs then you may require a professional woodworm survey to determine whether any treatment or professional solutions are needed to ensure that no more damage can be done to your structural or decorative timbers and that the woodworm larvae are exterminated from your home.

Woodworm sign 1 - small round exit holes

Tiny holes, between 1 and 3mm diameter, in the timber are perhaps the most obvious sign that you have a woodworm problem. These flight holes are created when the woodworm larvae pupate and hatch into adult beetles, boring their way to the surface of the timber to mate with other adult beetles and reproduce. Starting the whole woodworm lifecycle all over again.

Woodworm sign 2 - Fine, powdery dust

Bore-dust, also known as frass is the term given to the small, fine and powdery dust that is often found near woodworm exit holes. Frass is actually the droppings that woodowrm larvae produce as the burrow and chew their way through your wooden structures. If you see any 'exit holes' in your wood or timber then be sure to check frequently for evidence of frass, because this is a key sign that the infestation site is currently live.

Woodworm sign 3 - Tunnels within the timber

It may be possible to see a network of small tunnels that have been bored into the wood by the larvae as they burrow inside.

Woodworm sign 4 - Weak or damaged timber or floorboards

If you have noticed furniture, flooring or structural timber is noticeably weaker or started to crumble at the edges, then it could be a sign of woodworm.

Woodworm sign 5 - beetle activity or dead beetles outside of timber

If you notice beetles emerging from timbers, or dead beetles close to the proximity of holes then you more than likely have a woodworm infestation.

Images of a woodworm infestation

In their early stages woodworm infestations can be quite difficult to spot. Below are a selection of images displaying what woodworm infestations can look like in the property, however it should be noted that just because you have spotted exit holes or frass in the home, that does not necessarily mean that the site still contains a live infestation.
