How do I prevent insect damage in a timber home?

In Northern Europe, the primary insect risk is from woodworm (Anobium punctatum) and house longhorn beetle (Hylotrupes bajulus). Prevention measures include: maintaining timber moisture content below 16% (insects prefer damp timber), ensuring adequate ventilation in roof spaces and sub-floor voids, treating any new timber introduced during renovations, inspecting annually for flight holes (1–2 mm diameter for woodworm, 6–10 mm for longhorn beetle), and addressing any infestation promptly with professional treatment.
