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