Types of infestation

Woodworm applies generally to all insect attack found in buildings. The most widespread form of decay is that caused by the Common Furniture Beetle and can result in localised failure of floor joists and floorboards. The good news is that many infestations can be shown to be old and inactive and as such under COSHH Regulations (the Control of Substances Hazardous to Health) need not be treated.

Death Watch beetle Death Watch Beetle mainly attacks elm, oak and chestnut and is more usually found in large or old buildings where these timbers have been used.

Listed building House Longhorn Beetle can cause more serious damage than other insects. It only attacks the sapwood of softwoods and is only found in isolated areas in Southern England - at present. It is thought to be temperature dependent so will global warming encourage this insect to become more widespread?
