Why it matters
Woodworm is the UK's most overlooked timber pest
A 3–4 year larval lifecycle means active woodworm silently weakens timber for years before a single exit hole appears. By the time you spot the signs, the damage is already done — unless you know what to look for. Learn how professional treatment works or book a free survey.
~£1bn
Annual structural damage
Wood-boring beetles are estimated to cause close to £1 billion of structural timber damage across UK homes each year — the vast majority going undetected until a survey flags it.
75%
Common furniture beetle
Roughly three quarters of UK woodworm infestations are Anobium punctatum — the common furniture beetle. Correct species identification matters because treatment methods and guarantees differ by species. Species guide →
3–4 yrs
Lifecycle before holes appear
Larvae spend 3–4 years tunnelling through timber — completely invisible — before pupating and chewing an exit hole. The exit holes you see are a lagging indicator, not real-time damage. Spot it early →
Industry standards: All our surveys and treatments follow Property Care Association (PCA) guidance and BWPDA (British Wood Preserving and Damp-proofing Association) treatment standards — the same standards required by mortgage lenders when a timber report is requested.

The four tell-tale signs of woodworm
Caught early, woodworm is straightforward to treat. Our surveyors check for all four indicators — read our full identification guide or use this checklist to assess your own timber.
Round exit holes
Active infestation likely
Crisp 1–2mm holes in timber where adult beetles have emerged. Sharp, pale-edged holes with fresh frass beneath suggest a current, active infestation — older holes are darker at the rim.
How to identify woodworm holes →Bore dust (frass)
Adults emerging right now
Fine, gritty powder beneath or around holes — like tiny piles of cream-coloured sawdust on floors, skirting and windowsills. Fresh frass (lemon-curd coloured) means beetles are active this season.
Identifying fresh frass →Weak or crumbling wood
Structural damage present
Timber that gives way underfoot, crumbles at edges or sounds hollow when tapped — a sign larval tunnelling has gone deep into structural timber. Joists and rafters most at risk.
Is woodworm structurally dangerous? →Live or dead beetles
Flight season confirmed
Small brown beetles (3–5mm) near windows in May–September, or dead specimens in cobwebs and on sills. Common furniture beetles emerge from mid-spring; death watch beetles tap from March.

Not sure if it's active?
Our surveyors use specialist lighting, moisture meters and extraction tools to tell you definitively — at no charge for most homeowners.

UK woodworm species guide
Not all woodworm is the same. Correct identification determines the right treatment — and whether you have an urgent structural problem or a minor cosmetic issue. See the full species hub →
1–2mm Common Furniture Beetle
Moderate riskAnobium punctatum
The UK's most common woodworm — responsible for roughly three quarters of all infestations in homes.
3mm Death Watch Beetle
High riskXestobium rufovillosum
A hardwood specialist found in old oak and historic buildings — slow, persistent and structurally serious.
6–10mm (oval) House Longhorn Beetle
Very high riskHylotrupes bajulus
A rare but devastating softwood borer, concentrated in parts of Surrey and subject to specific building regulations.
1–2mm Powderpost Beetle
Moderate riskLyctus brunneus
Attacks the sapwood of hardwoods like oak and ash — often in newer flooring and recently imported timber.
1mm (ragged) Wood-Boring Weevil
Low riskEuophryum confine
A secondary pest of already-damp, decaying timber — its presence is a red flag for an underlying damp problem.
1–2mm Bark Borer Beetle
Low riskErnobius mollis
Confined to bark and waney edges of softwood — frequently misidentified as furniture beetle and rarely needs treatment.
Risk levels reflect the structural severity if left untreated. Full species identification guide →

The woodworm lifecycle: why early detection matters
The common furniture beetle spends the majority of its life inside the timber, invisible and silent. The exit holes you see are evidence of damage that happened 3–4 years ago. A free survey catches the larvae before the adults emerge — and before the structural bill escalates.
Eggs laid
Female beetles lay 20–60 eggs in cracks and end grain, May–Aug
Larvae tunnel
Grubs eat through timber for 3–4 years, unseen below the surface
3–4 years hiddenPupation
Larva pupates just under the surface, close to emergence
Adult emerges
Beetle chews exit hole and flies to mate — the first visible sign
Exit holes appear
The 1–2mm holes you discover — often years after infestation began
The only way to confirm active infestation is a professional survey — moisture readings, fresh frass sampling and species identification. Book yours free →
