Spotting and Stopping Woodworm: What Every Homeowner Needs to Know....

As we move into the warmer months between May and October, we see a noticeable rise in woodworm treatment enquiries. This seasonal increase is no coincidence — the adult beetles responsible for woodworm are most active during this time, laying eggs and beginning the cycle of infestation in vulnerable timber.

If you suspect woodworm in your home, it’s important to act quickly. Left untreated, it can cause serious structural damage and lead to costly repairs. Here's everything you need to know about spotting woodworm, understanding the damage it can cause, and deciding when to take action.

What is Woodworm?

Woodworm is the term used for the larvae of wood-boring beetles.

The most common species in the UK include the Common Furniture Beetle (Anobium punctatum) and, in more severe cases, the House Longhorn Beetle (Hylotrupes bajulus). These beetles lay their eggs in timber, and the larvae then burrow through the wood, feeding on it as they grow — often unnoticed for years.

How to Spot the Signs of Woodworm

Woodworm can often go undetected until damage becomes visible. Keep an eye out for these common signs:

• Small, round exit holes (typically 1–2mm in diameter) in wooden surfaces

• Fine powdery dust (frass) near the holes, a result of larvae tunnelling

• Tunnels within timber visible when wood is cut or broken

• Crumbly edges or weakened wood that breaks easily

• Adult beetles emerging from timber, often seen around windowsills or light sources

If you notice any of the above, it’s time to take a closer look.

What Damage Can Woodworm Cause?

Though tiny, woodworm larvae can cause significant structural damage over time. As they bore through beams, joists, floorboards, and furniture, they compromise the strength and stability of timber. In severe cases, untreated woodworm can:

• Weaken roof structures

• Damage floorboards and stairs

• Compromise the integrity of structural beams

• Lower the value of your property

Early intervention is key to preventing expensive repairs.

What You Can Do Yourself

If you think you’ve found woodworm, there are a few steps you can take:

• Inspect thoroughly: Look in lofts, under floorboards, in crawl spaces, and on exposed timber for signs.

• Improve ventilation: Woodworm thrives in damp conditions. Ensure your property is well-ventilated to reduce moisture in timber.

• Remove infested items: If the issue is limited to small furniture items, removing and treating or discarding them may be enough.

• Monitor activity: Place a white sheet below suspicious timber to check for fresh frass or emerging beetles during peak season.

However, if the infestation seems widespread, or affects structural timbers, it’s time to call in the professionals.
