Woodboring insects such as the Common Furniture Beetle (Anobium
Punctatum) and Wood Boring Weevil (Euophryum confine) are often
gathered under the generic term "woodworm".
The Common Furniture Beetle will attack all types of structural
timber and accounts for two thirds of all "woodworm"
damage to properties. It is most commonly found in older properties
although the beetle can also be found in more modern properties.
Very old properties can have holes which became inactive many
years ago and to the layman look identical to fresh holes where
damage is being done.

COMMON FURNITURE BEETLE
(ANOBIUM PUNCTATUM)
The surveyor will be able to determine if there is a problem
and prescribe the most appropriate treatment. Usually this involves
the application of a contact insecticide directly to the timbers
throughout the common flight area. This will prevent new attacks
and kill any adults as they emerge. As the life span of these
insects is three to four years there may be continued activity
from the current generation of larvae for this period.
Amongst the many other species of insects which attack structural
timber the Wood Boring Weevil is the most common. This insect
shares many similarities with the Common Furniture Beetle but
importantly it is found only in decaying timber. An application
of insecticide will kill the current generation but until the
source of the problem is tackled reinfestation may be a possibility.
Decaying timber is usually a sign of wet rot and the surveyor
will make a thorough investigation before deciding on treatment.
There is a common misconception that central heating will
"dry" the timbers in a property to a level where the
beetles cannot survive. A normal centrally heated home has a
natural moisture level that varies with the seasons and also
varies throughout the house. Relative humidity is naturally high
in summer when the central heating is off and this is when the
eggs are laid. Even when the heating is on during the winter
months many areas remain damp such as in the roof, the cellar
and in the floor joists. Indeed, the combination of central heating
and loft insulation can increase humidity levels encouraging
the insects to spread. Thus it is wise to check for damage in
properties of all ages.
