Signs of Active Woodworm Infestation — Book a Survey If You Spot Any
Woodworm damage is largely hidden — beetles bore through timber for years before the evidence becomes visible. These are the warning signs that indicate an active or recent infestation requiring professional assessment.
Small round exit holes in timber
Fresh holes with clean, sharp edges — typically 1–2mm for furniture beetles, larger for deathwatch beetles
Fine powdery dust (frass)
Cream-coloured bore dust beneath or around holes — the clearest sign of active larvae feeding inside the timber
Weak, crumbling or brittle wood
Timber that breaks apart easily under pressure — a sign of extensive internal tunnelling that may not be visible on the surface
Live or dead beetles
Adult beetles emerge between April and September — spotting them near timber, particularly in roof spaces or subfloors, confirms an active infestation
Tunnels visible in bare timber
Internal channels visible in split or damaged sections of wood, particularly in older joists, beams, and floorboards

⚠ Is Woodworm a Structural Risk? Yes — If Left Untreated.
Wood-boring beetles spend years feeding inside structural timber before emerging. By the time exit holes are visible externally, significant internal damage may already have occurred. The structural elements most at risk in London properties are:
Consequences of untreated infestations include sagging floors, weakened load-bearing timber, costly structural repairs, and complications during mortgage surveys or property sales. Early treatment is substantially cheaper than structural remediation.
Spotted Any of These Signs?
Don’t wait — woodworm damage compounds over time. PCAQT-certified specialists available across all London boroughs this week.

Why choose us
Why London Homeowners & Landlords Choose Damp & Mould Solutions
Many pest control companies treat the surface. We treat the cause. Woodworm infestations are driven by moisture — without addressing the underlying damp conditions, reinfestation is a matter of time.
🎓 PCAQT Certified Specialists
Every survey and treatment is carried out by a PCAQT-qualified timber specialist — not a generalist pest controller. The industry’s recognised standard for woodworm and timber infestation diagnosis.
💧 Moisture Control Included
Wood-boring beetles target damp timber. Unlike surface-only treatments, we assess and address the moisture conditions driving the infestation — reducing the risk of it recurring.
🔒 Guaranteed Work
Our treatments come with a written guarantee. If the infestation recurs within the guarantee period, we return and retreat at no additional cost. Ask about guarantee terms when you call.
📅 Same-Week Appointments
We cover all London boroughs and typically book within the same week. Pre-purchase surveys accommodated urgently — call 020 4542 6114 and we’ll prioritise you.

Our treatment process
A Proven Four-Stage Treatment Methodology
We don’t apply a blanket treatment and leave. Each property is assessed individually — because the right treatment for a Victorian subfloor is not the same as for a modern flat with a damp problem.
Woodworm Survey
PCAQT-certified specialist assesses timber, confirms active vs inactive infestation, identifies beetle species, and measures moisture — before recommending anything
Diagnosis first, alwaysTargeted Treatment
Permethrin-based surface treatments, deep injection for structural timber, or boron-based solutions for long-term protection — matched to your infestation, not a standard package
Species-specific treatmentTimber Repair
Where structural integrity is compromised, damaged timber is reinforced or replaced — restoring the section rather than just treating the surface
Structural restorationMoisture Control
We identify and address the damp conditions that attracted beetles in the first place — improving ventilation, reducing humidity, and advising on long-term protection
Prevents reinfestationImportant
Why DIY Woodworm Treatments Fail
Over-the-counter treatments are widely available, but the vast majority of cases we’re called back to treat are properties where DIY products were tried first. Here’s why.
Surface treatments alone do not reach larvae
DIY products
- Penetrate only a few millimetres into timber surface
- Cannot reach larvae tunnelling deep inside structural wood
- Do not address the moisture conditions attracting beetles
- Provide no guarantee or follow-up if reinfestation occurs
- Risk incorrect product for the beetle species present
Professional treatment
- Deep injection penetrates structural timber fully
- Species correctly identified before treatment selected
- Moisture cause assessed and addressed alongside treatment
- Written guarantee on all work carried out
- Structural repair included where timber is compromised
