What's the first sign of woodworm in a UK home?

Fresh round exit holes 1–2mm wide in a piece of timber, with pale 'frass' (wood dust) underneath, is the everyday opener.

When are woodworm most active during the day?

Adults emerge May–July. Deathwatch beetle (one of the species included under 'woodworm') makes a faint ticking from inside structural timbers — rare in modern UK homes, common in older oak frames.

How do I know it's woodworm and not something else?

Woodworm are most often mistaken for powder post beetle. Fresh, pale frass means active woodworm. Grey, compacted frass usually means a historic infestation that's already gone.

When does a woodworm sighting become urgent?

Holes appearing in load-bearing timbers (joists, lintels, roof trusses) — these need a structural survey alongside treatment.

Where do woodworm usually nest or hide?

Inside the timber itself. Larvae spend 2–5 years tunnelling inside the timber before emerging as adults — which is why a survey assesses age and activity, not just hole count.

Do I need to leave my home during woodworm treatment?

For most woodworm treatments, no. Woodworm treatment is a survey followed by targeted treatment and a follow-up visit, and the operator will brief you on any short re-entry window before they start.

Are woodworm treatments safe around children and pets?

Yes. UK-licensed operators use products approved for domestic use and will brief you on short re-entry windows. Woodworm protocols are designed around occupied homes, not empty buildings.

Do woodworm treatments come with a guarantee?

Standard woodworm jobs carry a 30-day guarantee; established cases usually 60–90 days. Any return visit inside the window is at no extra cost.

Pressure rises in autumn through late winter, when outside food collapses and they push indoors, and Atlantic damp on the west coast widens the harbourage window. Coverage spans L.
