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.

◉ 03 — Local context

Why woodworm thrive in Derby.

Derby is a city in East Midlands, and the local woodworm pressure is shaped by its building stock and street pattern. We see repeat activity in loft insulation and drains and broken gullies, with most ingress traced to fractured below-ground drains — and, on older stock, gaps under garage doors. Pressure rises in autumn through late winter, when outside food collapses and they push indoors, and the temperate midlands climate keeps activity steady year-round. Coverage spans DE1, DE21, DE22 and 3 more.

⊕ 04 — Treatment protocol

The Derby protocol.

For Derby jobs, a typical woodworm treatment is two to three visits with bait stations, proofing of entry points, and a CCTV drain check where activity suggests sewer ingress. Operators on our East Midlands network carry the relevant CRRU / RSPH certifications and provide a written report you can share with a Derby landlord, letting agent or the local environmental health team.

Typical woodworm treatment in Derby runs £285–£1425, in line with the wider East Midlands average.
