The name woodworm is the commonly used generic term for a number of wood boring insects. Pictured is evidence of Common Furniture Beetle, (Anobium punctatum). This wood boring insect is responsible for about 75% of all wood worm damage in this country and will attack soft and hardwoods.
Timber Section Affected With Common Furniture Beetle
Death Watch Beetle, Xestobium rufovillosum is most commonly found in hardwoods in the UK and prefers damp conditions which are improved when there is some kind of fungal decay such as wet rot in the timbers.
The bore-dust or frass forms into bun-shaped pellets, which helps to identify this form of infestation which can be miss identified with common furniture beetle.
These beetles are approximately twice the size of common furniture beetle and severe damage may be caused to timber, resulting in structural failure.
To attract mates, these woodborers create a tapping or ticking sound that can be heard in old building rafters. They are therefore associated with quiet, sleepless nights and are named for the vigil (watch) keepin besides the dying or dead with the superstitious therefore naming it the Death Watch beetle.
Timber Section Affected With Death Watch Beetle
Wood Boring Weevil
Death Watch Beetle
These particular insects attack timber associated with dampness or at least with a higher moisture content level than normal, usually found within sub floor void areas, affecting timber plates, floor joists and the underside of floor boarding, often where timbers are in contact with damp brickwork, plaster or masonry. This insect is more often than not found in association with Wet Rot decay of one species or another. The Wood Boring Weevil will expire once the source of dampness raising the moisture content level of timber has been reduced or removed. Lack of sub floor ventilation to floor voids, i.e. blocked or obstructed air bricks or the lack of air bricks, can increase the high moisture content level of timbers in floor voids.
No treatments are generally required for the treatment of this insect however the source of moisture needs to be eradicated and timbers seriously affected may require replacement.

These insects are what is commonly known in the preservation industry as a secondary insect Wood Boring Insect.
The first necessary step is a professional survey to locate the areas of infestation, identify accurately the species involved and determine whether it is active or not.
In domestic property it may be necessary to lift carpets, floorboards and gain access to roof voids. In many cases areas requiring treatment are obscured by a heavy accumulation of dust and old building debris. Prior to any treatment this must all be cleaned / cleared. Roof insulation also needs to be lifted to gain access to the timbers.
Premier Contractor’s use the latest and most suitable insecticidal formulations that eliminate the insects on contact as they pass through the spray treated timber. Deep seated Death Watch Beetle infestations, in large section structural hardwoods for instance, require a more targeted treatment and here a deeply penetrating insecticidal gel is employed.
